RESUMO: Os casos de abdome agudo estão entre as doenças mais prevalentes e desafiadoras na medicina equina. O diagnóstico inclui a realização de anamnese e avaliação clínica detalhada do paciente, permitindo a coleta de diversas informações importantes e, adicionalmente, a utilização de exames complementares ajuda a definir o diagnóstico e prognóstico de cada caso. O objetivo principal deste trabalho foi aplicar a análise de correspondência múltipla (ACM) em dados referentes ao exame clínico e desfecho de cavalos com cólica encaminhados para um hospital no Rio Grande do Sul, Brasil. Foram incluídos 58 cavalos na análise e foi possível identificar diferenças significativas entre os grupos, sobreviventes e não sobreviventes. Relacionado aos sinais clínicos, os casos de óbito distinguem-se por dor intensa, falta de motilidade, alteração da mucosa, tempo de preenchimento capilar maior que 2seg., frequência cardíaca maior que 48bpm e presença de refluxo nasogástrico. Como exames complementares, o hematócrito e o lactato sanguíneo demonstraram diferença significativa entre os grupos. Os parâmetros cardiovasculares, como batimento cardíaco, coloração de mucosas e tempo de preenchimento capilar, foram as variáveis com maior contribuição para diferenciar animais que não sobreviveram dos que receberam alta hospitalar. Assim, a avaliação clínica não deve ser subestimada e os exames complementares devem ser utilizados em conjunto para buscar um melhor prognóstico.

ABSTRACT: Acute abdomen cases are among the most prevalent and challenging illnesses in equine medicine. The diagnosis includes anamnesis and detailed clinical evaluation of the patient, allowing the gathering of several important information and, additionally, the use of complementary exams helps to define the diagnosis and prognosis of each case. This research applied the multiple correspondence analysis (MCA) in data referring to clinical examination information and outcome of horses with colic referred to a hospital in Rio Grande do Sul, Brazil. Fifty eight horses were included in the analysis and, it was possible to identify significant differences between the groups, survivors and non-survivors. Related to clinical signs, non-survivor cases are distinguished by severe pain, lack of motility, mucosal alteration, capillary refill time greater than 2sec, heart rate more than 48bpm and presence of nasogastric reflux. As complementary exams, hematocrits and blood lactate demonstrate significative difference among the groups. The cardiovascular parameters, including heart rate, mucosal color and capillary refill time, were the variables with the greatest contribution to discriminate animals that non-survive from those that were discharged. Thus, clinical evaluation should not be underestimated and complementary exams should be used in conjunction to seek a better prognosis. The MCA allowed to visualize the data and predict the outcome of the patients.

RESUMO: As neoplasias neuroepiteliais presentes no sistema ventricular originam-se das células que revestem o plexo coroide e podem ser benignas ou malignas, como é o caso do carcinoma de plexo coroide. Um equino, de quatro anos de idade, apresentando quadro neurológico com síndrome encefálica de quinze dias de evolução, foi encaminhado para atendimento veterinário. Ao exame apresentava apatia, ataxia severa, desvio lateral de cabeça, andar em círculos, pressão da cabeça contra obstáculos, diminuição do tônus da cauda, anosmia, ausência da resposta de ameaça visual, ausência de sensibilidade na face e hipotonia de língua. Líquido cefalorraquidiano apresentava pleocitose mista, aumento de proteína e diminuição de glicose. Após o óbito o animal foi diagnosticado com carcinoma de plexo coroide em terceiro ventrículo após exame histopatológico e imunohistoquímico. Conclui-se que equinos podem apresentar tumores em SNC, como o carcinoma de plexo coroide, com sintomatologia clínica inespecífica, tratamento clínico inefetivo e diagnóstico conclusivo realizado no exame post mortem.

ABSTRACT: Neuroepithelial neoplasms present in the ventricular system originate from the cells lining the choroid plexus and can be benign or malignant, such as choroid plexus carcinoma. A four-year-old equine presenting with a fifteen-day history of neurological symptoms was sent for veterinary evaluation. Upon examination, the horse exhibited apathy, severe ataxia, head tilt, circling behavior, head pressing, decreased tail tone, anosmia, absence of menace response, lack of facial sensitivity, and lingual hypotonia. Cerebrospinal fluid analysis revealed mixed pleocytosis, increased protein, and decreased glucose. Following the animal’s death, histopathological and immunohistochemical examinations confirmed the diagnosis of choroid plexus carcinoma in the third ventricle. It is concluded that horses may develop central nervous system tumors, such as choroid plexus carcinoma, with nonspecific clinical symptoms, ineffective clinical treatment, and a conclusive diagnosis established postmortem.

Abstract The objective of this study was to determine the mineralogical composition of equine enteroliths from the Aburrá Valley in Antioquia, Colombia. Samples of eight enteroliths from eight horses were subjected to semi-quantitative X-ray diffraction (XRD) and transmission and scanning electron microscopy (TEM/SEM) analysis. The TEM/SEM of the analyzed enteroliths reported the presence of carbon, oxygen, phosphorus, magnesium, calcium, silicon, potassium, bromine, iron, sulfur, and aluminum. The XRD identified struvite, newberyte, kyanite, low quartz, actinolite, nitratine, cordierite, and vivianite. Both techniques used in the analysis of the enteroliths were correlated by matching the mineral compounds with the detected chemical elements. The main mineral components of the enteroliths were magnesium phosphates, struvite and newberyte being the most common.

Muestras de ocho enterolitos de ocho caballos, fueron sometidas a análisis por Difracción de Rayos X Semicuantitativo (DRX) y microscopía electrónica de transmisión y barrido (METB). La METB de los enterolitos analizados reportó carbono, oxígeno, fósforo, magnesio, calcio, silicio, potasio, bromo, hierro, azufre y aluminio. A través de DRX se identificó estruvita, newberyta, kyanita, quartz low, actinolita, nitratina, cordierita, vivianita. Ambas técnicas empleadas en el análisis de los enterolitos se correlacionaron al coincidir los compuestos minerales, con los elementos químicos determinados. Los principales componentes minerales de los enterolitos fueron fosfatos de magnesio, siendo la estruvita y la newberyta los más comunes.

ABSTRACT The preparation of the boxer entails physiological changes and adaptations to guarantee the physical, psychological and social loads to which its practitioners have been subjected. Once this stage is completed, sports detraining appears, the nature of which is eminently pedagogical and consists of uninstalling the components that guaranteed the accumulation of loads during his time as an active boxer, until reaching the levels of a normal systematic practitioner of Physical Culture. The objective of this work was to design a pedagogical strategy based on a model of the same nature for detraining enhanced with equine-interaction-prophylactics, based on the use of exercises with horses as an element of change. Observation of sports sessions, document analysis, a survey of former boxers, coaches, sports doctors, officials and selected experts, as well as critical opinion and socialization workshops among boxing coaches, were used as empirical methods and techniques. As results, a pedagogical model was obtained from which a strategy was derived. These contributions were verified through the partial application of the strategy in a sports complex in Majibacoa, Las Tunas and its feasibility to be generalized was demonstrated. The article offered aims to socialize results of the research carried out on sports detraining in boxing enhanced with equine-interaction-prophylaxis. Conclusively, the theoretical and practical contributions demonstrated the fulfillment of the research objective and the solution of the scientific problem.

ABSTRACT The aim of this work was to evaluate the hydric status and serum cortisol concentration in horses during two cultural horseback rides in the municipalities of Granada and Acacías in the department of Meta (Colombia). For this, 88 animals were selected at convenience (44 per ride), taking blood samples 1 h before starting the ride (T0) and 15 min after finishing the ride (T1). In addition, a clinical examination was conducted to determine their hydric status (humidity of the mucous membranes, capillary refill time, skin turgor and eyeball retraction). In the blood test, micro haematocrit, total serum proteins and cortisol concentration were determined. The results of the variables between the two times were compared with the Shapiro Wilks and Wilcoxon tests. The Spearman test determined the correlations between age and sex with serum cortisol. There were no significant differences between the hydric status and the times evaluated; however, micro haematocrit, total serum proteins and cortisol presented lower values at T0 (p<0.001). On the other hand, no significant correlations were found between serum cortisol concentration with age and sex. The results suggest that cultural horseback riding is a stressful activity for the animal, determined by the significant increase in serum cortisol, with a tendency toward haemoconcentration that emphasizes the importance of correct hydration of horses before, during and after these events.

RESUMEN El propósito de este trabajo fue evaluar el estatus hídrico y la concentración de cortisol sérico en equinos durante dos cabalgatas culturales en los municipios de Granada y Acacías del departamento del Meta (Colombia). Se seleccionaron 88 animales a conveniencia (44 por cabalgata), tomando muestras de sangre 1 h antes de iniciar la cabalgata (T0) y 15 min después de terminar la cabalgata (T1), además de un examen clínico para determinar su estatus hídrico (humedad de las mucosas, tiempo de llenado capilar, turgencia de la piel y la retracción del globo ocular). En el análisis de sangre se determinó el micro hematocrito, proteínas séricas totales y concentración de cortisol. Los resultados de las variables entre los dos tiempos se compararon con las pruebas de Shapiro Wilks y de Wilcoxon. La prueba de Spearman determinó las correlaciones entre edad y sexo con el cortisol sérico. No hubo diferencias significativas entre el estatus hídrico con los tiempos evaluados; sin embargo, el micro hematocrito, proteínas séricas totales y cortisol presentaron valores menores en T0 (p<0.001). Por otro lado, no se encontraron correlaciones significativas entre la concentración sérica de cortisol con la edad y el sexo. Los resultados sugieren que las cabalgatas culturales son una actividad estresante para el animal, determinada por el incremento significativo de cortisol sérico, habiendo una tendencia a la hemoconcentración que recalca la importancia de la correcta hidratación de los equinos antes, durante y después de estos eventos de exigencia física.

Abstract 19. Gastrointestinal parasitism is very common in horses in northeastern Argentina, where it is often subclinical, leading to losses in body development and reduced animal performance. The objective of this study was to characterize the population of gastrointestinal nematodes in horses from the town of Gobernador Virasoro, Corrientes, used in the artisanal production of bricks. An observational cross-sectional descriptive study design was used and non-probability convenience sampling was performed. The number of eggs per gram of feces was determined by coprological examinations (modified McMaster technique), and all samples with the presence of gastrointestinal nematode eggs were considered positive. Morphologically, eggs of the order Strongylida were distinguished from eggs of Parascaris equorum and Oxyuris equi and the possible combinations between them. Parasitic genera of the order Strongylida were identified from pool coprocultures, differentiating between large and small strongyles. The results showed that 94.79% of the samples were positive, of which 83.43% corresponded to the order Strongylida only, 10.98% to the combination with eggs of P. equorum and 5.59% to the combination with eggs of O. equi. The highest average number of eggs belonged to the Strongylida order, with 90.55% corresponding to small strongyles. The results of this study suggest that gastrointestinal parasitism is a major problem in the working horse population of Gobernador Virasoro and could have a negative impact on animal health and performance.

Resumen 15. En el nordeste argentino son muy frecuentes las parasitosis gastrointestinales en los equinos, presentes de forma subclínica, provocando pérdidas en el desarrollo corporal y disminución en el rendimiento de los animales. El objetivo fue caracterizar la población de los nematodos gastrointestinales en equinos de la localidad de Gobernador Virasoro (Corrientes) a través del examen coprológico, utilizados como animal de trabajo en la fabricación artesanal de ladrillos. Se utilizó un diseño de estudio observacional transversal descriptivo, para ello se realizaron muestreos de conveniencia de tipo no probabilísticos. Se realizó el recuento de huevos por gramo de materia fecal mediante estudios coprológicos (técnica de McMaster modificada), donde se consideró como positivas a todas aquellas muestras con presencia de huevos de nematodos gastrointestinales. Se diferenció morfológicamente entre huevos del orden Strongylida y huevos de Parascaris equorum y Oxyuris equi, y las combinaciones que pudieran presentarse entre ellos. Los géneros parasitarios del orden Strongylida se identificaron a partir de coprocultivos en pool diferenciando entre grandes y pequeños estrongilos. El 94,79% de las muestras fueron positivas, de las cuales el 83,43% correspondieron únicamente al orden Strongylida, el 10,98% a la combinación con huevos de P. equorum, y el 5,59% a la combinación con huevos de O. equi. Los mayores promedios de recuentos de huevos pertenecieron al orden Strongylida, donde mediante coprocultivo se determinó que el 90,55% correspondió a pequeños estróngilos. Los resultados de este estudio sugieren que la parasitosis gastrointestinal es un problema importante en la población de equinos de trabajo de Gobernador Virasoro, y podrían tener un impacto negativo en la salud y el rendimiento de los animales.

Abstract 20. Dermacentor nitens is a Neotropical tick with reports from northern Argentina (provinces of Salta and Jujuy) to southern Mexico, with no records in Chile and Uruguay. Its main host is horses; likewise, this tick has veterinary importance due to its role as a vector of microorganisms. Thus, the aim of the present work is to provide new findings of D. nitens for the province of Corrientes, Argentina, thus expanding its distribution.

Por lo antes mencionado, el objetivo del presente trabajo es aportar nuevos hallazgos de D. nitens para la provincia de Corrientes, Argentina ampliando así su distribución.

RESUMO: O objetivo do presente estudo foi descrever a prevalência e os fatores associados à infecção por Brucellaspp. em equídeos de trabalho na região semiárida do Nordeste do Brasil. Amostras de sangue foram coletadas de 322 equídeos (76 equinos, 155 muares e 91 asininos). O teste de placa Rosa Bengala (RBPT) foi usado como método de triagem. As amostras que foram reativas no RBPT foram enviadas para confirmação usando 2-mercaptoetanol (2-ME) e o teste padrão de aglutinação em tubo (STAT). Ao todo, 7,1% (23/322) das amostras foram positivas segundo o RBPT. Após testes confirmatórios, a prevalência de brucelose foi de 6,5% (21/322). Destes casos, 33,3% (7/21) foram equinos, 42,8% (9/21) muares e 23,9% (5/21) asininos. Na análise multivariada, idade acima de 10 anos foi considerada fator associado à infecção (OR: 17,17; 95% CI: 2,582-164,7, P = 0.006) por Brucellas pp. A prevalência significativa de anticorpos anti-Brucella spp. encontrados em equídeos de trabalho e a ampla distribuição de animais positivos demonstra uma situação epidemiológica preocupante em relação à brucelose na região de estudo. A idade superior a 10 anos foi um fator de risco associado à infecção em animais.

ABSTRACT: The present study described the prevalence and factors associated with the seropositivity for anti-Brucella spp. antibodies in working equids in the semiarid regionofnortheastern Brazil. Blood samples were collected from 322 equids (76 horses, 155 mules and 91 donkeys). The Rose Bengal plate test (RBPT) was used as a screening method. Samples that were reactive in the RBPT were tested for confirmation using 2-mercaptoethanol (2-ME) and the standard tube agglutination test (STAT). Overall, 7.1% (23/322) of the samples were positive according to the RBPT. After confirmatory tests, the prevalence of brucellosis was found to be 6.5% (21/322). Among these cases, 33.3% (7/21) were horses, 42.8% (9/21) were mules and 23.9% (5/21) were donkeys. In the multivariate analysis, age over 10 years was considered to be a factor associated with the seropositivity (OR: 17.17; 95% CI: 2.582-164.7, P = 0.006) for anti-Brucella spp. antibodies. The significant prevalence of anti-Brucella spp. antibodies found in working equids and the wide distribution of positive animals demonstrates a worrying epidemiological situation regarding brucellosis in the study region. Age over 10 years was a risk factor associated with the seropositivity for anti-Brucella spp. antibodies in animals.

For more than two centuries, Beaufort West has been an essential stopover for people traversing an arid and sparsely populated region. Throughout its existence, the town has been plagued by water problems, whether they be drought, flash floods, or sanitary in origin. Many factors contributed to Beaufort West’s sanitary woes. Situated in the semi-arid central Great Karoo with an average rainfall of a mere 250mm, Beaufort West’s unique geographical positioning renders it climatologically vulnerable and because its water supply is heavily reliant on rainfall, regular droughts are inevitable. Groundwater extracted from boreholes has played an increasingly important role in the development of Beaufort West. Since the 1850s, it has been reliant on a very rudimentary potable water reticulation system of open street furrows, and a sewage system comprising cesspools and pail removals. Until the first half of the twentieth century many of the residents were self-sustaining and on their properties they kept farm animals such as pigs, sheep, goats, fowl and cows as food and horses as draught animals. These conditions created almost unsurmountable sanitation problems. The council minutes and sanitation reports of the Beaufort West Municipality frequently note the prevalence of two diseases – typhoid and diphtheria. This article investigates the root causes, manifestation, and health impact of these diseases on the community of Beaufort West. It traces the municipal initiatives to combat their occurrence, and the efforts made to improve the town’s general sanitary conditions. This case study of Beaufort West corroborates a hypothesis that modern-day outbreaks of water-borne diseases and sanitation in South Africa have a long historical antecedent.

Oor twee eeue heen, was Beaufort-Wes 'n noodsaaklike rushalte vir reisigers wat deur 'n droë en ylbevolkte omgewing gereis het. Sedert sy stigting is die dorp deurlopend geteister deur waterprobleme, hetsy droogte, vloedwater of besoedeling. Baie faktore het tot die dorp se gesondheidsprobleme bygedra. As gevolg van sy unieke geografiese ligging is die dorp klimatologies baie kwesbaar. Beaufort-Wes is in die sentrale Groot Karoo se semi-woestyn geleë, met 'n gemiddelde jaarlikse reënval van slegs 250 mm. Watervoorsiening aan die dorp is grotendeels van reënval afhanklik en gereelde droogtes is onvermydelik. Grondwater, wat deur middel van boorgate onttrek word, het deur die jare heen 'n toenemend belangrike rol in die ontwikkeling van Beaufort-Wes gespeel. 'n Baie rudimentäre waterverspreidingstelsel, wat oorspronklik uit oop straatleivore bestaan het, asook 'n rioolstelsel, bestaande uit nagemmer verwydering en putlatrines, is ontwikkel. Baie dorpenaars was selfonderhoudende inwoners wat plaasdiere soos varke, skape, bokke, hoenders en koeie as voedselbronne op hul eiendomme aangehou het. Hierdie situasie het byna onoorkomelike gesondheidsprobleme opgelewer. Twee waterdraende siektes -ingewandskoors en witseerkeel - het vir baie jare met reëlmaat opgeduik in die notules en gesondheidsverslae van Beaufort-Wes se munisipaliteit. Die studie ondersoek die oorsake, manifestering en gesondheidsimpak van hierdie siektes op die gemeenskap van Beaufort-Wes, asook die munisipale inisiatiewe wat aangewend is om die voorkoms daarvan te bestry en pogings om die dorp se algemene gesondheidstoestand te verbeter. Die gevallestudie van Beaufort-Wes bevestig die hipotese dat moderne uitbrekings van waterdraende siektes en sanitasie in Suid-Afrika 'n lang historiese aanloop het.

ABSTRACT Equine influenza is a highly contagious viral disease, specially among 1-5 years old naive horses. Vaccination is considered the best way to control the disease spread and outbreaks. Although foals are the main animal used for evaluation of equine influenza vaccines, guinea pigs were chosen as an alternative model in the present work, as they have a negligible antibody titer against equine influenza virus and are cheaper and easier to handle than foals. Five equine influenza vaccine batches were evaluated in two animal models, foals and guinea pigs, by injection of two doses/animal with 4 weeks apart using 2 mL/animal/dose and evaluation of immune responses by hemagglutination inhibition test and enzyme-linked immunosorbent assay. On the 7th week post vaccination, equine influenza antibodies titers reached maximum values of 9-10.2 and 8.7-10 hemagglutination inhibition units for foals and guinea pigs, respectively; sample/negative ratios were 0.126-0.464 and 0.128-0.445 for both animals, respectively. The use of guinea pigs as an animal model for the evaluation of equine influenza vaccines could be recommended instead of foals.

RESUMEN La gripe equina es una enfermedad viral muy contagiosa, especialmente entre los caballos jóvenes de 1 a 5 años de edad. La vacunación se considera la mejor forma de controlar la propagación y los brotes de la enfermedad. Aunque los potros son el principal animal utilizado para la evaluación de vacunas contra la gripe equina, en el presente trabajo se eligieron cobayos como modelo alternativo, ya que tienen un título insignificante de anticuerpos contra el virus de la gripe equina y son más baratos y fáciles de manejar que los potros. Se evaluaron cinco lotes de vacunas contra la gripe equina en dos modelos animales, potros y cobayos, mediante la inyección de dos dosis/animal con 4 semanas de intervalo utilizando 2 mL/animal/dosis y la evaluación de las respuestas inmunitarias mediante la prueba de inhibición de la hemaglutinación y el ensayo inmunoenzimático. En la 7ª semana posvacunación, los títulos de anticuerpos contra la gripe equina alcanzaron valores máximos de 9-10,2 y 8,7-10 unidades de inhibición de la hemaglutinación para potros y cobayos, respectivamente; las relaciones muestras/negativos fueron de 0,126-0,464 y 0,128-0,445 para ambos animales, respectivamente. Podría recomendarse el uso de cobayos como modelo animal para la evaluación de vacunas contra la gripe equina, en lugar de potros.

In southern Africa game farming has become an effective way of using underutilised resources and a valuable method of preserving and increasing wildlife numbers. However, little is known about the mineral requirements of wild animal species or the assessment of the mineral nutritional status of these species. To establish criteria for estimating the copper (Cu) nutritional status of wildlife, current knowledge about Cu metabolism and criteria for domestic animals has been used. Since the Cu metabolism of ruminants differs substantially from that of non-ruminants, Cu metabolism in domestic species such as cattle and sheep representing wild ruminants, and pigs and horses as non-ruminant species, has been scrutinised to propose criteria for wild bovids in southern Africa. In the adequate range of dietary Cu intakes, literature suggests that hepatic Cu concentrations in ruminants increase linearly with an increase in Cu intake, allowing a relatively reliable measure of sufficiency. In non-ruminants, hepatic Cu concentrations follow a lag phase during which hepatic Cu concentrations remain relatively constant with increasing dietary Cu intakes of more that 25 times their requirements. A consequence is that non-ruminants can tolerate much higher dietary levels of Cu compared to ruminants. It is proposed that at liver Cu concentrations of < 20 mg/kg dry matter (DM), a wild ruminant could benefit from Cu supplementation; liver Cu concentrations of between 20 and 300 mg Cu/kg DM suggest an adequate Cu intake; concentrations of 300 to 500 mg/kg DM indicate a potentially unhealthy accumulation of Cu, while liver Cu concentrations of > 500 mg/kg DM indicate that the animal probably consumed more Cu than required and might be at risk of developing Cu toxicosis.

The main aim of this pilot study was to determine how the energy spectrum of scatter radiation emitted from horses after injection of the radiopharmaceutical 99mTechnetium-methyl diphosphonate (99mTc-MDP), changed behind lead shielding of varying thicknesses (0.25 mm, 0.35 mm, and 0.5 mm Pb thickness), and if beam hardening occurred. The effect lead shielding has on the emitted gamma radiation energy spectrum has not been documented. In particular, the presence of beam hardening effects behind lead shielding was investigated, to determine whether or not it could discourage the use of lead shields during bone scintigraphy in horses. Horses were injected intravenously with 99mTc-MDP, and energy spectra emitted from horses without lead shielding were recorded initially to determine the emitted scatter spectrum. Thereafter, different combinations of lead shields of the various thicknesses listed above, draped over the horse and on simulated personnel, were recorded. The energy spectra were obtained at different anatomical locations of five horses on five consecutive days with a pulse height (multichannel) analyser two and a half hours post-injection. Energy spectra recorded from horses without lead shielding showed polychromatic energy spectra that encompassed a large portion of predominantly lower scatter energies (averaging around the 88-94 keV peaks). Higher 99mTc-MDP peaks averaging at 139-143 keV (useful for gamma camera acquisition) were consistently seen in all recordings but made up a very small part of the emitted spectra. With the application of lead shielding, peaks of 83-86 keV, which coincided with K-edges of lead, occurred. No significant beam hardening effects behind lead shields of varying thicknesses were observed. Thus, the wearing of lead shields during bone scintigraphy of horses is encouraged.

Abstract Antimicrobial resistance in bacteria isolated from horses represents a threat to global health due to the close relationship of these animals with humans. This study aimed to elucidate the antimicrobial susceptibility profiles of bacteria with pathogenic and zoonotic potential, isolated from the respiratory and genital tracts of horses in Mayabeque, Cuba. Nasal and genital exudates were collected from twenty-three horses, and the isolates obtained were identified using the analytical profile index and mass spectrometry. The minimum inhibitory concentration (MIC) of thirteen antibiotics was determined for the isolates. Twenty-three bacterial isolates, including one Streptococcus uberis, sixteen Enterococcus spp., three Staphylococcus sciuri, one Morganella morganii, and two Stenotrophomonas maltophilia, were obtained. S. uberis showed resistance to gentamicin, enrofloxacin, and doxycycline, while enterococci isolates displayed resistance to doxycycline (n=16), rifampicin (n=8), erythromycin (n=7), enrofloxacin (n=3), and chloramphenicol (n=1). All S. sciuri isolates were resistant to at least six antibiotics, including methicillin, with high MIC values for erythromycin (>8192 µg/ml), doxycycline (128 µg/ml), and gentamicin (64 µg/ml). M. morganii isolate was resistant to three antibiotics, with MICs of 128 μg/ml and 256 μg/ml for cefquinome and doxycycline, respectively. S. maltophilia isolates exhibited resistance to cefquinome, with MIC values of 512 μg/ml and 128 μg/ml, respectively. The 91.3% of the isolates were multiresistant to antimicrobials, which represents the first detection in Cuba of bacteria with multiresistance phenotypes, isolated from samples of the nasal and genital mucosa of horses.

Resumen La resistencia a antimicrobianos en bacterias aisladas de caballos representa una amenaza para la salud mundial debido al estrecho vínculo de estos animales con los humanos. El objetivo de este estudio fue describir los perfiles de susceptibilidad a antimicrobianos de bacterias con potencial patogénico y zoonótico, aisladas de los tractos respiratorio y genital de caballos procedentes de Mayabeque, Cuba. Se recopilaron exudados nasales y genitales de veintitrés caballos, y se utilizó el índice de perfil analítico y espectrometría de masas para realizar la identificación de los aislados obtenidos. Se determinó la concentración mínima inhibitoria (CMI) de trece antibióticos, frente a los aislados. Se obtuvieron veintitrés aislados bacterianos (un Streptococcus uberis, dieciséis Enterococcus spp., tres Staphylococcus sciuri, un Morganella morganii y dos Stenotrophomonas maltophilia). S. uberis mostró resistencia a gentamicina, enrofloxacina y doxiciclina. Los aislados de enterococci fueron resistentes a doxiciclina (n=16), rifampicina (n=8), eritromicina (n=7), enrofloxacina (n=3) y cloranfenicol (n=1). Todos los aislados de S. sciuri fueron resistentes al menos a seis antibióticos incluyendo meticilina, con altos valores de CMI para eritromicina (>8192 µg/ml), doxiciclina (128 µg/ml) y gentamicina (64 µg/ml). El aislado de M. morganii fue resistente a tres antibióticos con CMIs de 128 μg/ml y 256 μg/ml para cefquinoma y doxiciclina, respectivamente. Los aislados de S. maltophilia mostraron resistencia a cefquinoma con valores de CMI de 512 y 128 μg/ml respectivamente. El 91,3% de los aislados resultaron multirresistentes a antimicrobianos, lo cual representa la primera detección en Cuba de bacterias con fenotipos de multirresistencia, aisladas de muestras de la mucosa nasal y genital de caballos.

RESUMO: Bothrops atrox é a serpente mais comum na Amazônia, e seu veneno provoca alterações locais e sistêmicas. Este relato descreve os achados clínico-patológicos e laboratoriais de ofidismo por Bothrops em seis equídeos no Pará, Brasil. Os animais, que pertenciam a cinco propriedades rurais diferentes, apresentaram sinais clínicos de apatia, anorexia e aumento da sensibilidade ao toque em áreas de aumento de volume. Três animais foram picados na parte distal dos membros pélvicos e três na região da cabeça. Os animais afetados na área dos membros pélvicos apresentaram edema acentuado que se estendia do boleto até a coxa e exibiam dificuldade de locomoção. Aqueles afetados na região da cabeça exibiam aumento de volume que conferia a aparência de uma “cabeça de rinoceronte”, bem como escurecimento da mucosa dos lábios e gengivas. Todos os animais apresentaram taquicardia e taquipneia, e os achados laboratoriais de dois animais evidenciaram anemia, leucocitose, aumento do tempo de coagulação e aumento das enzimas hepáticas (AST e GGT) e renais (ureia e creatinina). O tratamento foi ineficaz, e três dos quatro animais tratados faleceram. A necropsia foi realizada em três animais e foi observada hemorragia extensa no tecido dos locais da picada da serpente e líquido sanguinolento incoagulável nas cavidades. Observou-se congestão no diafragma, na serosa do intestino delgado e áreas mais claras na superfície renal. A histopatologia mostrou degeneração muscular, necrose, necrose tubular aguda, hemorragia e cilindros hialinos nos rins. Este relato destaca os achados clínico-patológicos de picada de serpente em equídeos. Além disso, parece ser o primeiro relato de envenenamento por Bothrops em uma mula no Brasil.

ABSTRACT: Bothrops atrox is the most common viper in the Amazon, and its venom causes local and systemic changes. This report describes the clinicopathological and laboratory findings of ophidism due to Bothrops in six horses in Pará, Brazil. The animals, which belonged to five different rural properties, showed clinical signs of apathy, anorexia, and increased touch sensitivity in areas of increased volume. Three animals were bitten in the distal part of the pelvic limbs and three in the head area. The affected animals in the distal limb area exhibited marked edema extending from the fetlock to the thigh and had difficulty moving. Those affected in the head region exhibited an increase in volume that gave the appearance of a “rhinoceros head,” as well as blackening of the mucosa of the lips and gums. All animals exhibited tachycardia and tachypnea, and laboratory findings of two animals showed anemia, leukocytosis, increased clotting time, and elevated liver (AST and GGT) and kidney enzymes (urea and creatinine). Treatment was ineffective, and three of four treated animals died. Necropsy was performed on three animals, revealing extensive hemorrhage in the tissues at the snake bite sites and incoagulable bloody fluid in the cavities. Congestion was observed in the diaphragm, in the serosa of the small intestine, and in lighter areas on the renal surface. Histopathology showed muscle degeneration, necrosis, acute tubular necrosis, hemorrhage, and hyaline casts in the kidneys. This case report highlights the clinicopathological findings of snakebite in horses. In addition, this seems to be the first report of bothropic envenom in a mule in Brazil.

ABSTRACT Vesicular stomatitis virus is the causative agent of the vesicular stomatitis disease, which mainly affects cattle, swine, and horses causing significant economic losses. Many other animal species, including humans, can be also affected by the disease. Up to now, the epidemiology of vesicular stomatitis disease is not well understood. Previous epidemiological studies in Central America described the existence of an association between the presence of vesicular stomatitis New Jersey virus antibodies and environmental risk factors such as mean annual rainfall, temperature, and elevation. Additionally, molecular epidemiology studies revealed that the phylogenetic relationship between vesicular stomatitis New Jersey virus isolates is more related to ecological factors than temporal factors. We have performed a genetic analysis of vesicular stomatitis virus samples isolated from animals in different geographical regions in Venezuela. We sequenced the hypervariable region of the phosphoprotein gene of 51 samples collected over eight years. The virus was found in a wide range of environmental conditions, at high and low altitudes and with variable levels of precipitation and temperatures. In contrast with previous reports, our phylogenetic analysis showed that viruses from different ecological regions did not present significant genetic differences. cattle swine losses species humans now understood rainfall temperature elevation Additionally Venezuela 5 years conditions temperatures reports differences
