Resumo A hibernação é uma condição natural dos animais que vivem na zona temperada, embora alguns lagartos tropicais também experenciem hibernação anualmente, como é o caso do lagarto nativo da América do Sul, Salvator merianae ou “teiú”. Embora as características fisiológicas e metabólicas associadas à hibernação tenham sido amplamente estudadas, possíveis alterações na integridade das hemácias durante esse período ainda permanecem obscuras. A desidratação e o jejum são consequências naturais da hibernação por vários meses e podem estar relacionadas a algumas modificações celulares. Neste estudo, investigamos se a tolerância osmótica de hemácias do lagarto teiú sob hibernação são diferentes das células obtidas de animais em atividade normal. Além disso, investigamos indiretamente por meio da quantificação de biomoléculas oxidadas e da atividade de enzimas antioxidantes se a membrana das hemácias dos teiús em hibernação poderia estar associada à oxidação. Nossos resultados sugerem que as hemácias possuem maior fragilidade durante o período de hibernação, embora não tenhamos encontrado evidências de um cenário de estresse oxidativo associado à essa fragilidade acentuada. Embora não tenhamos excluído a possibilidade de dano oxidativo durante a hibernação, sugerimos que um aumento no volume das hemácias como consequência de sangue hipoosmótico durante a hibernação também poderia afetar a integridade de hemácias, tal como foi observado.

Abstract Hibernation is a natural condition of animals that lives in the temperate zone, although some tropical lizards also experience hibernation annually, such as the lizard native from South America, Salvator merianae, or “tegu” lizard. Even though physiological and metabolic characteristic associated with hibernation have been extensively studied, possible alterations in the red blood cells (RBC) integrity during this period remains unclear. Dehydration and fasting are natural consequences of hibernating for several months and it could be related to some cellular modifications. In this study, we investigated if the osmotic tolerance of RBCs of tegu lizard under hibernation is different from the cells obtained from animals while normal activity. Additionally, we indirectly investigated if the RBCs membrane of hibernating tegus could be associated with oxidation by quantifying oxidized biomolecules and the activity of antioxidant enzymes. Our findings suggest that RBCs are more fragile during the hibernation period, although we did not find evidence of an oxidative stress scenario associated with the accentuated fragility. Even though we did not exclude the possibility of oxidative damage during hibernation, we suggested that an increased RBCs volume as a consequence of hypoosmotic blood during hibernation could also affect RBCs integrity as noted.

Resumen Introducción: Aunque COVID-19 (enfermedad por coronavirus 2019) en niños es usualmente leve, en casos excepcionales requieren hospitalización y cuidados intensivos. Los resultados adversos han sido observados principalmente en los niños con comorbilidades, justificando su vacunación. El objetivo de este estudio fue evaluar el riesgo de hospitalización y muerte en niños y adolescentes mexicanos con COVID-19 y comorbilidades. Métodos: Estudio transversal en 366,542 casos de COVID-19 confirmados, menores de 18 años y reportados por la Secretaría de Salud de México, hasta el 9 de julio del 2022. Se ejecutaron modelos multivariados de regresión logística. Resultados: El promedio de edad fue de 10.98 años, 50.6% de sexo masculino, y 7.3% reportaron al menos una comorbilidad. El porcentaje de hospitalización y muerte en pacientes con COVID-19 sin comorbilidades fue 3.52% y 0.20%, respectivamente; mientras que los pacientes con comorbilidades presentaron más elevados porcentajes de hospitalización (14.0%) y muerte (1.9%). La probabilidad de hospitalización fue 5.6 veces más en los pacientes con COVID-19 y comorbilidades, comparando con aquellos sin comorbilidades. Las comorbilidades que mostraron más riesgo fueron inmunosupresión (razón de momios (RM) 22.06), enfermedad renal crónica (ERC) (RM 11.36) y enfermedades cardiovasculares (RM 5.66). La probabilidad de muerte en los pacientes con comorbilidades fue 11.01 veces más que en aquellos sin enfermedades, y fue más elevado en aquellos con ERC (RM 12.57), enfermedades cardiovasculares (RM 6.87) y diabetes (RM 5.83). Conclusiones: Los pacientes pediátricos con comorbilidades presentaron mayor riesgo de COVID-19 severo, por lo que se sugiere promover con mayor énfasis la vacunación en ellos.

Abstract Background: Although COVID-19 (coronavirus disease 2019) in children is usually mild, they need hospitalization and intensive care in exceptional cases. Adverse outcomes have been observed mainly among children with comorbidities, justifying their vaccination. This study aimed to assess the risk of hospitalization and death in Mexican children and adolescents with COVID-19 and comorbidities. Methods: A cross-sectional study was performed on 366,542 confirmed COVID-19 cases under 18 years, reported by the Mexican Ministry of Health up to July 9, 2022. Logistic regression models were performed. Results: The mean age was 10.98 years, 50.6% were male, and 7.3% reported at least one comorbidity. The percentage of hospitalization and death in COVID-19 patients with and without comorbidities was 3.52%, and 0.20%, respectively; children with comorbidities presented a higher percentage of hospitalization (14.0%) and death (1.9%). The probability of hospitalization was 5.6 times greater in pediatric patients with COVID-19 and comorbidities, and the comorbidities that showed the greatest risk were immunosuppression (odds ratio (OR) 22.06), chronic kidney disease (CKD) (11.36), and cardiovascular diseases (5.66). The probability of death in patients with comorbidities was 11.01 times higher than in those without diseases, and the highest risk was observed in those with CKD (OR 12.57), cardiovascular diseases (6.87), and diabetes (5.83). Conclusions: Pediatric patients with comorbidities presented a higher risk of severe COVID-19. It is suggested that vaccination should be promoted with greater emphasis on pediatric patients with comorbidities.

Abstract A new species of whitefly, Aleuropleurocelus petenensis sp. nov. Carapia-Ruiz & García-Ochaeta, found on leaves of a plant belonging to the genus Acalypha (Euphorbiaceae) in Petén, Guatemala, is described based on characteristics of the pupa. This new species exhibits a black venter and has microtubercles on the subdorsal and submedian areas, whereas the most closely related species, A. mixtecus Carapia-Ruiz, presents a pale venter and has not microtubercles on the corresponding areas. In both species the transverse suture of the molt ends before the apparent margin and the dorsal surface presents folds; these features support the close relationship between these species. Microphotographs of morphological structures of the new species puparium are provided.

Resumen Una nueva especie de mosca blanca, Aleuropleurocelus petenensis sp. nov. Carapia-Ruiz & García-Ochaeta, encontrada sobre hojas de una planta perteneciente al género Acalypha (Euphorbiaceae) en Petén, Guatemala, es descrita basada en características de la pupa. La nueva especie presenta vientre negro y tiene microtubérculos en el área subdorsal y submediana, mientras que la especie más cercanamente relacionada, Aleuropleurocelus mixtecus Carapia-Ruiz, tiene el vientre pálido y no presenta microtubérculos en las áreas correspondientes. En ambas especies la sutura transversa de la muda termina antes de margen aparente y la superficie dorsal presenta pliegues; estas características apoyan la cercana relación entre estas especies. Microfotografías de estructuras morfológicas del pupario de la nueva especie son presentadas.

Abstract Background Infectious endocarditis (IE) refers to infection of the endocardial surface of the heart and usually occurs in native or prosthetic valves. Objective This study aimed to raise IE data reflecting the surgical therapy in a University Hospital in the interior of the State of Sao Paulo–Brazil. Method Retrospective and observational approach of 328 patients with IE who underwent surgery between 1982 and 2020 Results The main data (n=121/37%), congestive heart failure (n=114/35%), valve disease (n=92/28%), diabetes mellitus (n=85/26%), chronic kidney disease (n=59/18%), and rheumatic fever (49/15%). Renal failure is one of the main and most relevant pre-surgical risk factors for a poor prognosis. Conclusion For a better clinical and surgical outcome, an early syndromic and etiological diagnosis of IE is necessary, especially in patients with multiple comorbidities.

Abstract Objectives: To evaluate the inconsistency between clinical diagnosis of death and autopsy findings in adolescents with chronic diseases. Methods: A cross-sectional study including a sample of adolescents’ autopsies who died in a pediatric and adolescent tertiary hospital over 18 consecutive years. During this period, there were n = 2912 deaths, and n = 581/2912(20%) occurred in adolescents. Of these, n = 85/581(15%) underwent autopsies and were analyzed. Further results were divided into two groups: Goldman classes I or II (high disagreement between main clinical diagnosis of death and anatomopathological findings, n = 26) and Goldman classes III, IV or V (low or no disagreement between these two parameters, n = 59). Results: Median age at death (13.5 [10‒19] vs. 13 [10‒19] years, p = 0.495) and disease duration (22 [0‒164] vs. 20 [0‒200] months, p = 0.931), and frequencies for males (58% vs. 44%, p = 0.247) were similar between class I/II vs. class III/IV/V. The frequency of pneumonia (73% vs. 48%, p = 0.029), pulmonary abscess (12% vs. 0%, p = 0.026), as well as isolation of yeast (27% vs. 5%, p = 0.008), and virus (15% vs. 2%, p = 0.029) identified in the autopsy, were significantly higher in adolescents with Goldman class I/II compared to those with Goldman class III/IV/V. In contrast, cerebral edema was significantly lower in adolescents of the first group (4% vs. 25%, p = 0.018). Conclusion: This study showed that 30% of the adolescents with chronic diseases had major discrepancies between clinical diagnosis of death and autopsy findings. Pneumonia, pulmonary abscess, as well as isolation of yeast and virus were more frequently identified at autopsy findings in the groups with major discrepancies.

Abstract This study aimed to characterize the spatial distribution and composition of living Benthic Foraminifera (BF) and to comprehend how environmental conditions (e.g., organic matter) can affect communities of these protozoa in the northern and southern sectors of the Santos Basin (SB), in the continental slope and São Paulo Plateau. In this context, 23 stations (65 samples including replicates at each station) were collected between 400 and 2,400 m water depth. Multivariate analyses revealed that the ecological structure of the community changes mainly along the bathymetric gradients. Stations located between 400 and 700 m, both in northern and southern sectors, are characterized by the presence of indicator species of high intensity of currents, such as Globocassidulina subglobosa and Trifarina bradyi. These stations are also mainly marked by the occurrence of Epistominella exigua, a phytodetritivore species. The stations at 1,000 and 1,300 m depth, in both sectors, are characterized by high accumulation of organic matter in the sediments, which favors the development of agglutinated foraminifera species, such as those of the genus Reophax. Finally, the lower slope and the São Paulo Plateau, in both sectors, are oligotrophic regions, with pulses of labile organic carbon, probably low current velocities and the presence of Alabaminella weddellensis. The quantity and quality of food, which are closely related to hydro-sedimentary dynamics and bentho-pelagic coupling in the slope and São Paulo Plateau, are the main factors that influence the distribution of living BF assemblages in the SB.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

BACKGROUND The parasite Giardia duodenalis infects a wide range of vertebrate hosts, including domestic and wild animals as well as humans. Giardia is genotyped into eight assemblages (A-H). Zoonotic assemblages A and B have already been identified in humans and wild and domestic animals (non-human primates and cats) from Brazilian Amazon and in the world. Due to its zoonotic/zooanthroponotic nature, surveillance initiatives and the definition of Giardia assemblages are important in order to characterise the epidemiological scenario and to implement further control measures. OBJECTIVES Determine assemblages of G. duodenalis in sloths from the Brazilian Amazon Region. METHODS Faecal parasitological examination of sloths from Amazonas State. Polymerase chain reaction (PCR) targeting the beta giardin (BG), and genes from multilocus sequence typing (MLST) scheme, amplicon sequencing and phylogenetic analysis. FINDINGS Here, we identified, by microscopy, Giardia in two northern sloths (Bradypus tridactylus). These two samples were submitted to molecular assays and it was revealed that both were infected by G. duodenalis assemblage A. Phylogenetic analysis showed that they belong to assemblage A within sequences from humans and wild and domestic animals. CONCLUSION Therefore, besides showing, by the first time, the current presence of this parasite in sloths, our findings reveals that this wild animal species would be part of the zoonotic/zooanthroponotic scenario of this parasite in the Brazilian Amazon.

Resumo A consciência sobre o papel vital do solo para a natureza e a sociedade tem vindo a aumentar. Atualmente, o solo é um dos eixos prioritários dos programas de investigação, desenvolvimento e inovação na Europa. Para desenhar estratégias de investigação eficazes é necessário identificar o atual grau de conhecimento bem como as suas lacunas. Com esse objetivo, este estudo reuniu informação sistemática de vinte e três países europeus sobre os impactos das práticas sustentáveis de gestão do solo agrícola. As equipas de cada país identificaram o conhecimento sobre as práticas e seus impactos, partindo de um total de trinta práticas pré-definidas e agrupadas em quatro grupos (Lavoura e cobertura do solo, Culturas e sistemas culturais, Nutrição e proteção de plantas e Gestão da água). Os impactos foram relacionados com os desafios do solo definidos pelo European Joint Programme Soil. Os resultados mostram que o conhecimento está bastante difundido por práticas dos quatro grupos, quer a nível europeu quer regional. Há uma grande variabilidade no grau de conhecimento ou de disseminação das práticas relacionadas com os diferentes desafios do solo. A necessidade de maior conhecimento sobre as práticas para diminuir as emissões de gases de efeito estufa dos solos agrícolas pôde ser claramente identificada.

Abstract The awareness about the vital role of soil for nature and society has been increasing. Soil is presently a priority in European research, development, and innovation programs. In order to design effective research strategies, there is the need to identify the current knowledge level and its gaps. With that aim, this study collected systematic information from twenty three European countries about the impacts of sustainable soil management practices. Each team reported impacts of sustainable practices, based on a total of thirty predefined practices, grouped in four management groups (Soil tillage and cover, Crop and cropping system, Nutrient management and crop protection, and Water management). The impacts were related to the soil challenges defined by the European Joint Programme Soil. The results show that the knowledge is rather well spread over practices in the four management groups, both generally and regionally. There was a high variability in the level of knowledge or awareness about the practices related to the different soil challenges. The need for further knowledge on practices to decrease greenhouse gas emissions from agricultural soils could be clearly identified.

ABSTRACT The study’s objective is to analyze the influence of the variable cities of residence, gender, marital status, and level of education on social physical anxiety (AFS) and its dimensions “Comfortable With Your Physique Appearance - CASF” and “Negative Expectation with Your Physique Appearance- ENCASF”. In the study, 384 individuals who practiced physical exercises responded to the Social Physical Anxiety Scale adapted by Malheiro and Gouveia (2001). In the treatment of data, descriptive and inferential statistics were used. The results made it possible to conclude that the subjects who practiced physical exercises showed different levels of social physical anxiety. There are statistically significant differences in the variables cities of residence, school level in the negative expectation with your physique appearance dimension. It is also concluded that there are statistically significant differences in the variables Cities of Residence and sex in the Negative Expectation with Your Physic Appearance dimension.

RESUMO A ansiedade física social (AFS) é um atributo psicológico que leva um sujeito a inquietar-se com o que acha que os outros imaginam em relação ao seu estado físico, aparecendo o exercício físico como feramente que propicia também os ganhos sociopsicológicos. O objetivo do estudo é analisar a influência das variáveis Cidades de residência, sexo, estado civil e grau de escolaridade na AFS e nas suas dimensões confortável com a aparência do seu físico (CASF) e expectativa negativa com aparência do seu físico (ENCASF). Participaram no estudo, 384 indivíduos praticantes de exercícios físicos que responderam à Escala de Ansiedade Físico Social adaptada por Malheiro e Gouveia (2001). No tratamento dos dados recorreu-se à estatística descritiva e inferencial. Os resultados possibilitaram concluir que os sujeitos praticantes de exercícios físicos apresentaram níveis diferenciados da AFS, sendo que, existem diferença estatisticamente significativas das variáveis cidades de residência x grau da escolaridade. Também se conclui que existem diferença estatisticamente significativas das variáveis cidades de residência x sexo na dimensão ENCASF.

ABSTRACT Perineal hernia results from weakening and/or the inability of the pelvic diaphragm to support the rectal wall, promoting caudal displacement of abdominal or pelvic organs in the perineum. Unneutered male dogs aged between 7 and 10 years are the most affected, being rare in females. The main clinical signs are unilateral or bilateral swelling of the perineal region, associated or not with tenesmus, dysuria, urinary and/or fecal incontinence, anuria and pain during defecation. The diagnosis is based on clinical history, anamnesis, physical examination, and complementary tests such as radiography and ultrasound. Clinical treatment can be done in some cases, but surgical intervention is required to resolve the problem. The present work aims to report the case of a patient treated at the FullPet Veterinary Clinic in Guarulhos, São Paulo, Brazil, a 7-year-old male Yorkshire canine, unneutered, weighing 4.5 kg. The same was submitted to surgery by the traditional method of suture with nylon thread and enteropexy. When there was recurrence, surgical reintervention was necessary to correct the hernia using a polypropylene mesh.

RESUMEN La hernia perineal resulta del debilitamiento y/o incapacidad del diafragma pélvico para sostener la pared rectal, lo que promueve el desplazamiento caudal de los órganos abdominales o pélvicos en el perineo. Los perros machos no castrados de entre 7 y 10 años son los más afectados, siendo raro en las hembras. Los principales signos clínicos son tumefacción unilateral o bilateral de la región perineal, asociada o no a tenesmo, disuria, incontinencia urinaria y/o fecal, anuria y dolor durante la defecación. El diagnóstico se basa en la historia clínica, la anamnesis, el examen físico y pruebas complementarias como la radiografía simple y la ecografía. El tratamiento clínico se puede hacer en algunos casos, pero se requiere una intervención quirúrgica para resolver el problema. El presente trabajo tiene como objetivo relatar el caso de un paciente atendido en la Clínica Veterinaria FullPet de Guarulhos, São Paulo, Brasil, un canino Yorkshire macho de 7 años, sin castrar, con un peso de 4,5 kg. Fue intervenido quirúrgicamente por el método tradicional de sutura con hilo de nylon y enteropexia. Cuando hubo recidiva, fue necesaria la reintervención quirúrgica para corregir la hernia mediante una malla de polipropileno.

RESUMEN Introducción: La infección relacionada con catéter venoso central (CVC) es la complicación más frecuente y grave en los pacientes en hemodiálisis, asociada a una elevada mortalidad y morbilidad. En España, se ha publicado una incidencia de bacteriemia de 0.9 a 2 episodios por catéter y año. Diversas variables se han relacionado con la tasa de bacteriemia asociada a CVC, tales como disfunciones del catéter, la formación y experiencia del personal de enfermería, el número de sesiones de hemodiálisis y la duración de las mismas. El objetivo del presente estudio es analizar la influencia de las variables citadas en la aparición de bacteriemias, en pacientes portadores de catéteres en una unidad de hemodiálisis de un hospital de tercer nivel en España. Material y métodos: Estudio analítico, observacional y retrospectivo en el que se obtuvieron los datos relativos a la formación recibida y experiencia del personal de enfermería, el número y duración de sesiones de hemodiálisis por paciente y disfunciones de CVC. Se contabilizaron las bacteriemias acontecidas en un año, a través de la base de datos de la unidad, y se analizó la posible relación de tales variables en la tasa de bacteriemia. Resultados: Sobre un total de 41 catéteres tunelizados en 35 pacientes, observados durante 365 días, se obtuvo una tasa de incidencia de 1.45/1000 días de catéter, no habiendo encontrada relación estadísticamente significativa con la formación del personal de enfermería (p=0.330), experiencia (p=0.668), número de disfunciones y manipulaciones de catéter (p=0.718; p=0.118). Se objetivó relación inversa con el número y duración de sesiones (p=0.02). Conclusiones: Es preciso seguir analizando la relación entre las variables mencionadas y la tasa de bacteriemias. Abordarlo desde un punto de vista multicéntrico o aumentar el tiempo de observación de forma prospectiva pueden ser aspectos a tener en cuenta para determinar las variables que parecen tener una relación directa con la infección de CVC, que en otros contextos se ha llegado a evidenciar.

ABSTRACT Introduction: Central venous catheter (CVC)-related infection is the most frequent and serious complication in hemodialysis patients, associated with high mortality and morbidity. In Spain, an incidence of bacteremia of 0.9 to 2 episodes per catheter and year has been published. Variables have been related to the rate of bacteremia associated with CVC, such as catheter malfunctions, the training and experience of the nursing, the number of hemodialysis sessions and their duration. The objective of the present study is to analyze the influence of the aforementioned variables on the appearance of bacteremia in patients with catheters in a hemodialysis unit of a tertiary care hospital in Spain. Methods: Analytical, observational, and retrospective study in which data on the training received and experience of the nursing staff, the number and duration of hemodialysis sessions per patient and CVC dysfunctions were obtained. The bacteremia’s that occurred in a year were counted, through the unit’s database, and the possible relationship of such variables in the rate of bacteremia was analyzed. Results: On a total of 41 tunneled catheters in 35 patients, observed for 365 days, an incidence rate of 1.45/1000 catheter days was obtained, not having found a statistically significant relationship with the training of nursing staff (p = 0.330), experience (p=0.668), number of dysfunctions and manipulations of catheter (p=0.718; p=0.118). An inverse relationship was observed with the number and duration of sessions (p=0.02). Conclusions: It is necessary to continue analyzing the relationship between the mentioned variables and the rate of bacteremia. Approaching it from a multicenter point of view or increasing the observation time prospectively may be aspects to consider to determine the variables that seem to have a direct relationship with CVC infection, which has been shown in other contexts.

Resumen: Desde 2015, se observó una alta mortandad de plantas de frutilla en el norte de Uruguay relacionada con enfermedades de corona y raíz causadas por un complejo de patógenos. En 2016, asociado con la muerte de plantas, Cylindrocarpon spp. se aisló con una frecuencia de 42,4 %, ocupando el tercer lugar, precedido por Neopestalotiopsis sp. y Fusarium spp. Con el objetivo de incrementar el conocimiento de los patógenos que integran el complejo, se caracterizaron tres aislados de Cylindrocarpon spp. mediante análisis moleculares, morfológicos y de patogenicidad en plantas de frutilla. Se identificó Dactylonectria novozelandica como agente causal de necrosis de corona y raíz de frutilla en Salto, Uruguay.

Abstract: Since 2015, a high mortality rate of strawberry plants has been observed in the north of Uruguay related to crown and root diseases caused by a pathogens complex. In 2016, associated with the death of plants, Cylindrocarpon spp. was isolated with a frequency of 42.4 %, ranking third, preceded by Neopestalotiopsis sp. and Fusarium spp. Aiming to increase the knowledge of the pathogens that integrate the complex, three isolates of Cylindrocarpon spp. were characterized by molecular, morphological and pathogenicity analyses in strawberry plants. Dactylonectria novozelandica was identified as causal agent of crown and root necrosis of strawberry in Salto, Uruguay.

Abstract This work aimed to associate sexual behavior with serum testosterone and the height of sensitive epithelium of vomeronasal organ (VNO) of Nellore bulls raised extensively and subjected to the VNO blocking during pre-puberty. Thirty-four bulls were divided into three groups. G1 (control group; n = 11): animals were kept intact; G2 (n = 10): animals had their incisive ducts bilaterally cauterized; G3 (n = 13): animals were bilaterally orchy-epiectomized. Five libido tests and blood sampling were performed in three months intervals from pre-puberty until sexual maturity. VNO were collected for histological evaluations by sacrificing the bulls weighting 480 kg. The experiment was conducted in a complete randomized design. No differences in libido among groups were observed in the first three tests. Attempt to mount, complete mount and the libido score increased at the fourth libido test only for the G1. Scenting and licking increased while the Flehmen reflex (FR) decreased at the fifth libido test for G2 and G3. Positive association between the FR and VNO sensitive epithelium height in G2 was observed. The olfactory stimuli entrance in the VNO is influenced by the Flehmen reflex, and that such organ plays a key role in the libido of Nellore bulls.

Resumo Objetivou-se avaliar o comportamento sexual e suas correlações com as concentrações séricas de testosterona e a altura do epitélio sensitivo do órgão vomeronasal (OVN) em machos Nelore (Bos taurus indicus), criados extensivamente e submetidos ao bloqueio do OVN na pré-puberdade. Foram utilizados 34 animais: G1-animais controle, denominados inteiros (n=11), G2-animais com os ductos incisivos bilateralmente cauterizados, denominados bloqueados (n=10) e G3-animais bilateralmente orquiepidectomizados, denominados castrados (n=13). Os animais foram avaliados a cada três meses até a maturidade sexual, sendo realizados cinco testes de libido e coletas de sangue. Foram abatidos os animais com 480 kg, onde foram obtidos os OVN, para avaliação histológica. O delineamento experimental foi inteiramente casualizado. Não houve diferenças (P>0,05) entre grupos nos primeiros três testes de libido. No quarto teste, houve aumento da tentativa de monta, monta completa e escore da libido apenas nos grupos dos inteiros (P<0,05). No quinto teste, houve aumento em cheirar e lamber e redução no reflexo de flehmen (RF) nos bloqueados e castrados (P<0,05). Observou-se alta associação entre o RF e altura do epitélio sensitivo do OVN nos bloqueados (r=0,75; P=0,05). Concluiu-se que a entrada dos estímulos olfatórios ao OVN é influenciada pelo RF e que este órgão exerce importante função no comportamento sexual em machos Nelore.
