RESUMO: Em geral, alelopatia pode ser definido como o processo biológico no qual um organismo produz metabolitos que alteram a germinação, o crescimento, a sobrevivência e a reprodução de outros organismos, influenciando a estabilidade de agroecossistemas. O colesterol, o mais abundante esterol isolado da alga vermelha marinha Plocamium brasiliense, foi estudado quanto ao seu potencial efeito inibitório na germinação de sementes, alongamento das radículas e desenvolvimento do hipocótilo das ervas daninhas Mimosa pudica (malicia) e Senna obtusifolia (mata-pasto). Colesterol foi isolado do extrato em Hexano por métodos cromatográficos. Durante 15 dias, os bioensaios de germinação foram realizados a 25 ºC e fotoperíodo de 12 horas, enquanto os bioensaio de alongamento da radícula e do hipocótilo foram realizados a 25 ºC e fotoperíodo de 24 horas. Posteriormente, placas de Petri de 9,0 cm de diâmetro foram revestidas de papelfiltro, e 25 sementes foram mantidas em câmaras de germinação, enquanto seis sementes pré-germinadas foram postas em placas de Petri por 2-3 dias. Após dez dias, a extensão da radícula e do hipocótilo foi medida. O potencial inibitório do colesterol foi avaliado a 5, 10, 15 e 20 ppm. Em ambas as ervas M. pudica e S. obtusifolia, foram afetadas significativamente pela ação do cholesterol alcançando maiores percentuais de inibição na germinação das sementes (50% e 33%, respectivamente), alongamento da radícula (68% e 60%, respectivamente) e desenvolvimento do hipocótilo (66% e 55%, respectivamente). Os efeitos inibitórios foram dose-dependentes em todos os experimentos, tendo efeitos alelopaticos mais acentuados a 20 ppm.

ABSTRACT: In general, allelopathy can be defined as a biological process by which an organism produces one or more metabolites that can change the germination, growth, survival, and reproduction of other organisms, and thus influencing the stability of agroecosystems. Cholesterol is a very abundant sterol isolated from the marine red alga Plocamium brasiliense that has been studied regarding its potential inhibitory effects on seed germination, radicle elongation, and hypocotyl development of the weeds Mimosa pudica (malicia) and Senna obtusifolia (mata-pasto). Cholesterol was isolated from a hexane extract by chromatographic methods. Over a 15-day period, germination bioassays were performed at 25 ºC with a 12-h photoperiod. Radicle elongation and hypocotyl development were assayed at 25 ºC with a 24-h photoperiod. Later, Petri dishes 9.0 cm in diameter were coated with filter paper, and 25 seeds were placed in a germination chamber. Six pre-germinated seeds were placed in the Petri dish for 2-3 days. After 10 days, radicle and hypocotyl extensions were measured, and the inhibitory potential of cholesterol was assessed at 5, 10, 15, and 20 ppm. In both herbs, M. pudica and S. obtusifolia, they were significantly affected by the action of cholesterol, achieving higher percentages of inhibition in seed germination (50% and 33%, respectively), radical germination (68% and 60%, respectively), and hypocotyl development (66% and 55%, respectively). The inhibition effects were dose-dependent in all experiments, having more pronounced allelopathic effects at 20ppm.

Summary: The cocoa crop is very susceptible to nutritional deficiencies and moniliasis caused by the phytopathogen Moniliophthora roreri. One of the alternatives to synthetic chemicals are compounds based on silicon (Si). In the present investigation, the ef fect of silicon as a biostimulant in cocoa cultivation and as a biological control agent for M. roreri was evaluated. In the experiment, five Si treatments were used: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) and T4 (1.5 kg ha-1) and a control treatment (without application). Production indicators, ear number, fresh and dry weight of almonds, dry weight of 100 almonds and crop yield were determined. In addition, the incidence and severity of the disease at 60, 120 and 180 days af ter the application of Si and the ef ficiency of the treatments. The significantly higher results for the variables: Production, ear number, fresh and dry weight of almond and dry weight of 100 almonds, were obtained by applying 4 kg ha-1 of Si, all doses of Si exceeded the control (P ≤ 0.05) in the variables related to production. In the control of the phytopathogen (M. roreri), the dose of 4 kg ha-1 Si decreased the incidence and severity of the disease by more than 50%. The application of Si can be an option in cocoa cultivation as a biostimulant and biological control agent for M. roreri.
Resumen: El cultivo del cacao es muy susceptible a deficiencias nutrimentales y a la moniliasis ocasionada por el fitopatógeno Moniliophthora roreri. Una de las alternativas a los productos químicos sintéticos son los compuestos a base de silicio (Si). En la presente investigación se evaluó el efecto del silicio como bioestimulante en el cultivo de cacao y agente de control biológico de M. roreri. En el experimento se utilizaron cincos tratamientos de Si: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) y T4 (1.5 kg ha-1) y un tratamiento control (sin aplicación). Se determinaron los indicadores de producción, número de mazorca, peso fresco y seco de almendras, peso seco de 100 almendras y el rendimiento del cultivo. Además, de la incidencia y severidad de la enfermedad a los 60, 120 y 180 días después de la aplicación del Si y la eficiencia de los tratamientos. Los resultados significativamente superiores para las variables: Producción, número mazorca, peso fresco y seco de almendra y peso seco de 100 almendra, se obtuvieron mediante la aplicación de 4 kg ha-1 de Si, todas las dosis de Si superaron al control (P ≤ 0.05) en las variables relacionas a la producción. En el control del fitopatógeno (M. roreri), la dosis de 4 kg ha-1 Si disminuyó la incidencia y la severidad de la enfermedad en más del 50%. La aplicación de Si puede ser una opción en el cultivo de cacao como bioestimulante y agente de control biológico de M. roreri.

Abstract Jalisco is one of the main honey bee producing states in Mexico. However, information on the parasitoses that affect the productivity of honey bee (Apis mellifera) colonies in the state is limited and addresses only a few regions. The objective of this study was to determine the prevalence and intensity of two parasitic diseases of Apis mellifera -varroosis (Varroa destructor) and nosemosis (Vairimorpha spp.)- in six regions of Jalisco. Bees from 365 colonies collected during the spring were analyzed. Varroosis was the most frequent parasitosis (90 %), and nosemosis was the least frequent (15 %). The infestation or infection levels of these parasitoses were generally low: <5 % (mites per 100 bees) for varroosis, and <310,000 spores/bee for nosemosis. The regions with the highest prevalence and intensity of V. destructor were the Highlands, the Center, and the South, while infections by Vairimorpha ceranae -the only species of the fungus found- were significantly higher in the Southeastern and Southern regions. It is advisable to carry out epidemiological studies at other times of the year in order to detect possible seasonal effects of parasitoses for the purpose of designing strategies for their control.
Resumen Jalisco es uno de los principales estados productores de miel de abejas en México. Sin embargo, la información sobre parasitosis que afectan la productividad de las colonias de abejas melíferas (Apis mellifera) en el estado es limitada y de pocas regiones. El objetivo de este estudio fue determinar la prevalencia e intensidad de dos enfermedades parasitarias de Apis mellifera, varroosis (Varroa destructor) y nosemosis (Vairimorpha spp.), en seis regiones de Jalisco. Se analizaron abejas de 365 colonias colectadas durante la primavera. La varroosis fue la parasitosis más frecuente (90 %) y la nosemosis la menos frecuente (15 %). Los niveles de infestación o infección de las parasitosis fueron en general bajos. Para varroosis, <5 % (ácaros en 100 abejas) y para nosemosis, <310,000 esporas/abeja. Las regiones con mayor prevalencia e intensidad de V. destructor fueron Altos, Centro y Sur, mientras que las infecciones por Vairimorpha ceranae, la única especie del hongo encontrada, fueron significativamente más altas en las regiones Sureste y Sur. Se recomienda realizar estudios epidemiologicos en otras épocas del año para detectar posibles efectos estacionales de las parasitosis para diseñar estrategias para su control.

Abstract 20. In Peru, cattle fasciolosis is an important problem in the livestock industry, causing economic losses, being widely distributed and whit endemic livestock areas. This study was carried out to determine the prevalence and risk factors in the Arequipa region. A total of 1,838 fecal samples were examined using the metal mesh sieving technique and the sediment was examined under a microscope. The owner was interviewed to learn about the management characteristics of his livestock. The data were analyzed by a multiple logistic regression model, ANOVA was used for the variables to show significance (p<0.05) and the Odds Ratio was calculated for the factors within the variables, with risk values greater than 1. The prevalence of bovine fasciolosis in the Arequipa region was moderate (34.65%), and the prevalence by provinces was 70.30%, 61.98%, 32.05%, 12.91%, 12.71%, and 3.57% for Caylloma, Condesuyos, Islay, Castilla, Arequipa, and Camaná, respectively. The risk factors for Fasciola hepatica infection that showed significance (p<0.05) were the age of juveniles and adults, the water consumed from the ditch/ river, the dosage every 6 and 12 months, and the locations of Machaguay, Chuquibamba, Iray, Andaray, Canocota, Chivay, Coporaque, Ichupampa, Achoma, Maca, Cabanaconde, Polobaya, San José de Uzuña, Vítor, Mollendo, Huambo, La Joya, Viraco, Piaca, and Pocsi. The results of the present study suggest the implementation of a control program through training, periodic treatment, and improvement in cattle management.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract This study examined the taxonomic composition and ecological aspects of planktonic green algae (Chlorophyta) in four urban ponds (Parque da Lagoa, Lagoa Grande, Laguneville, and Pindoba) in Feira de Santana, Bahia State, Brazil. We analyzed 96 samples collected bimonthly in 2022 and identified 54 taxa, with the majority (42) classified as uncommon or sporadic. The most common species were Monoraphidium circinale and Lemmermannia komarekii, found in 100% and 95.8% of samples, respectively. Parque da Lagoa had the highest number of taxa (43), followed by Lagoa Grande (40), Laguneville (31), and Pindoba (30). Most taxa were found in water with high levels of oxygenation (5.8-12.3 mg L−1) and conductivity (400-1000 μS cm−1), neutral to slightly alkaline conditions (pH 7-8), and moderate water temperature (26-27 °C). Significant differences in the composition of planktonic green algae and limnological variables were observed among ponds. These studies underscore the importance of implementing actions aimed at the restoration and conservation of urban ponds in Feira de Santana to avoid biodiversity loss and eutrophication while ensuring the provision of critical ecosystem services, such as local climate regulation.

Abstract Mexico is one of the world’s foremost producers and exporters of bees’ honey (Apis mellifera L.), and the state of Jalisco is one of the top three honey producers in Mexico. However, the Mexican beekeeping industry is affected by the high defensive behavior and lower honey production of Africanized honey bees compared to European bees. The objective of this study was to determine the African or European ancestry of honey bee colonies in six regions of temperate and subtropical climates in the state of Jalisco, Mexico, using morphometric and mitochondrial DNA analyses. More than 50% of the colonies in Jalisco had African mitotype and morphotype (59.0% and 62.5%, respectively). The frequency of africanization of the studied colonies was significantly higher (p < 0.05) in regions of low altitude and in subtropical climates, such as the Southeast and Southwest regions, than in regions of higher elevation and in temperate climates, such as Los Altos. There was a significant correlation between the forewing length of the bees and the altitude at which their colonies were located (r = 0.51, p< 0.01), indicating that the lower the altitude, the higher the degree of africanization of the bees. Future studies are warranted to determine if the degree of africanization of honey bee colonies increases or remains in equilibrium. These studies will make it posible to design mitigation strategies against the negative effects of the africanization of honey bees.
Resumen México es de los principales productores y exportadores de miel de abejas (Apis mellifera L.) a nivel mundial y el estado de Jalisco se encuentra entre los tres primeros productores a nivel nacional. Sin embargo, la apicultura mexicana es afectada por el alto comportamiento defensivo y menor productividad de las abejas africanizadas en comparación con abejas europeas. El objetivo de este estudio fue determinar la ancestría africana o europea de colonias de abejas melíferas en seis regiones de clima templado y subtropical en el estado de Jalisco, México, mediante análisis morfométricos y de ADN mitocondrial. Más del 50% de las colonias de abejas de Jalisco tuvieron mitotipo y morfotipo africano (59.0 y 62.5%, respectivamente). La frecuencia de africanización de las colonias fue significativamente mayor (p < 0.05) en regiones de baja altitud y climas subtropicales (regiones Sureste y Suroeste), que en regiones de mayor elevación y en climas templados (región de los Altos). Hubo correlación significativa entre la longitud del ala de las abejas y la altitud a la que se encontraban las colonias (r = 0.51, p < 0.01); esto indica que a menor altitud hay un mayor grado de africanización de las abejas. Se recomiendan realizar estudios para determinar si el grado de africanización de las colonias de abejas aumenta o se mantiene en equilibrio, lo que permitirá diseñar estrategias de amortiguamiento de los efectos negativos de la africanización de las abejas melíferas.

Abstract Root-knot nematodes affect the production of habanero pepper (Capsicum chinense Jacq.) and the use of antagonistic microorganisms is an option for their control. The objective was to evaluate native consortia of arbuscular mycorrhizal fungi (AMF) and Trichoderma spp. (TRI) for the management of M. incognita (Mi) in C. chinense. Five treatments established under protected conditions: AMF + Mi, TRI + Mi, AMF + TRI + Mi, Vydate 24% nematicide (Oxamil) + Mi and a control with only Mi. Each treatment had 15 replicates. The AMF + Mi treatment decreased the galling index, the number of eggs and females by 56, 48 and 26.29% in relation to Oxamil. The highest growth of the plants achieved with AMF + Mi with higher effects than the nematicide and control. The AMF + Mi and AMF + TRI + Mi treatments promoted better physiological functioning of the plants.

Resumen Introducción: Aunque el tratamiento del mieloma múltiple ha avanzado en los últimos años con el subsecuente aumento en la supervivencia a largo plazo, la mortalidad temprana sigue siendo un fenómeno trascendental, donde las infecciones pueden tener un papel fundamental, por lo que el entendimiento de la epidemiología local puede ayudar a dirigir las medidas de profilaxis antimicrobiana e impactar en desenlaces en la evolución temprana de la enfermedad. Métodos: Se realizó un estudio descriptivo donde se incluyeron 169 pacientes mayores de 18 años hospitalizados en un centro de alta complejidad en Medellín, Colombia, en el periodo de tiempo comprendido entre enero de 2012 y junio de 2021, con máximo 3 meses de diagnóstico confirmado de mieloma múltiple. Se recogieron variables sociodemográficas y clínicas basales de los pacientes, y se describió la presencia de infecciones, los aislamientos microbiológicos y antimicrobianos utilizados. Resultados: De 169 pacientes con mieloma múltiple de reciente diagnóstico, 95 (56.2%) de los pacientes presentaron alguna infección. De los cuales, las infecciones respiratorias y urinarias fueron las más comunes (ambas 15.4%). Los gérmenes más aislados fueron los bacilos gram negativos (33.7%) y los cocos gram positivos (21.1%). Con respecto al uso de profilaxis, la mayoría de los pacientes recibió antiviral 107 (63.3%), azoles 98 (58%), y pocos antibióticos 29 (17.2%). En cuanto al tiempo de aparición de infecciones, los pacientes tuvieron un promedio de 24 días desde el momento del ingreso hospitalario, y de 8 días desde el momento del inicio de la quimioterapia. Con relación a la mortalidad por cualquier causa en los primeros 3 meses, se presentó en el 24% y de estos, 2 tercios estuvieron relacionados con procesos infecciosos. Conclusión: Las infecciones en los pacientes con mieloma múltiple de reciente diagnóstico son una causa importante de mortalidad, a pesar de los esfuerzos preventivos y terapéuticos de las últimas décadas. Se documenta un cambio en la epidemiología de los gérmenes que afectan a estos pacientes. Por esto, es menester reconocer las infecciones en el ámbito hospitalario en mieloma múltiple para establecer guías de manejo locales.
Abstract Introduction: Although the treatment of multiple myeloma has advanced in recent years with a subsequent increase in long-term survival, early mortality remains a transcendental event, where infections may play a key role, understanding the local epidemiology may help to direct antimicrobial prophylaxis measures and impact on outcomes in the early evolution of the disease. Methods: We conducted a descriptive study including 169 patients older than 18 years hospitalized in a high-complexity health center in Medellin, Colombia, in the period between January 2012 and June 2021, with a maximum of 3 months of confirmed diagnosis of multiple myeloma. Baseline sociodemographic and clinical variables of the patients were collected, and the presence of infections, microbiological and antimicrobial isolates used were described. Results: Out of 169 patients with newly diagnosed multiple myeloma, 95 (56.2%) of the patients had some infection. Of these, respiratory and urinary tract infections were the most common (both 15.4%). The most isolated germs were gram-negative bacilli (33.7%) and gram-positive cocci (21.1%). Regarding the use of prophylaxis, most patients received antiviral 107 (63.3%), azoles 98 (58%), and few antibiotics 29 (17.2%). Regarding the time of onset of infections, patients had an average of 24 days from the time of hospital admission, and 8 days from the time of initiation of chemotherapy. In relation to all-cause mortality in the first 3 months, 24% were present and of these, 2 thirds were related to infectious processes. Conclusion: Infections in patients with newly diagnosed multiple myeloma are an important cause of mortality, despite preventive and therapeutic efforts in recent decades. A change in the epidemiology of the germs affecting these patients has been documented. Therefore, it is necessary to recognize infections in the hospital setting in multiple myeloma in order to establish local management guidelines.

ABSTRACT Introduction: Acute myeloid leukemia (AML) is most commonly presented in older adults; however, it appears 10 years earlier in Latin American countries. Clinical evolution in older adults from this populations has not been characterized. We analyzed outcomes and survival predictors. Methods: Patients ≥ 55 years old diagnosed with AML at a hematology referral center from 2005 to 2020 receiving intensive chemotherapy (IC), low-dose cytarabine (LDAC) and best supportive care (BSC) were included. Survival analysis included the Kaplan-Meier and Cox models and the cumulative incidence of relapse (CIR). Results: Seventy-five adults were included and the overall survival (OS) was 4.87, 1.67 and 1.16 months, using IC, LDAC and BSC, respectively. The IC led to a higher OS (p < 0.001) and was a protective factor for early death, at a cost of more days spent hospitalized and more non-fatal treatment complications; non-significant differences were found between the LDAC and BSC. Eight (10.7%) patients underwent hematopoietic cell transplantation, with a higher OS (p = 0.013). Twenty (26.7%) patients achieved complete remission; 12 (60%) relapsed with a 6-month CIR of 57.9% in those < 70 years old vs. 86.5% in those ≥ 70 years old, p = 0.034. Multivariate analysis showed the white blood cell count (WBC) and IC had a significant impact on the patient survival, whereas chronological age and the Charlson comorbidity index (CCI) did not. Conclusion: AML in low-middle income countries demands a different approach; the IC improves survival, even with a high incidence of relapse, and should be offered as first-line treatment. Eligibility criteria should include WBC and a multidimensional evaluation. The age per se and the CCI should not be exclusion criteria to consider IC.
