(Área UNAWEB) Sun, 05 Jun 2022 00:00:00 -0600 OJS 60 Evidence of porcine circovirus type 3 (PCV3) in a swine farm in Costa Rica <p>The presence of the pathogen Porcine Circovirus 3 (PCV3) is reported for the first time in Costa Rica in a swine farm located in the province of Cartago. The Real Time PCR technique was used. From a total of 56 pools of blood samples from animals with respiratory symptomatology and emaciation, 32 tested positive (57.14%) for PCV3, while 24 tested negative (42.86%). Only one case tested positive for PCV2 and negative for PCV3. The presence of this disease in the country must be monitored in order to know its epidemiology and its possible impact on the national swine herd.<br><span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p> Laura Chaverri, Fernando Chacón, Evelyn Espinach Roel, Daniel Zeledón ##submission.copyrightStatement## Fri, 01 Jul 2022 00:00:00 -0600 Post mortem findings and bacterial characterization of equine salmonella septicemia. A case report <p>The first duly confirmed case of equine salmonellosis in Costa Rica is described, a seven-month-old Ibero-American filly with a four-week-long case of diarrhea and poor body condition. The presence of Salmonella enterica subspecies enterica was confirmed through a bacteriological study of stool samples. In the post-mortem study, severe extensive ulcerative and necrotizing typhlocolitis was observed.<br><span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p> Enid Segura, Ernesto Rojas Sánchez, Carla Murillo, Patricio Razquín, Lohendy Muñoz, Elias Barquero-Calvo, Alejandro Alfaro-Alarcón ##submission.copyrightStatement## Fri, 01 Jul 2022 00:00:00 -0600 Evaluation of the physiological, hematological and biochemical profile related to the physiology of the exercise of horse submitted the lace modality <p>The objective of this research was to verify the physiological, hematological and biochemical parameters of horses submitted to the lace modality in the State of Mato Grosso do Sul. Six males and two females were evaluated in two moments, before and after the exercise, characterized as M0 and M1. Regarding the physiological parameters, referring to rectal temperature, heart rate and respiratory rate in the M0 were (37,23 ± 0,25, 42,75± 6,22 and 29,75 ± 8,77), respectively, while in the M1 (37,97 ± 0,34, 64,35 ± 13,34, 60,87 ± 11,28), showing an increase after the loop test. In the erythrogram, only a change in the VCM result was observed after the exercise, as it occurs due to the increase of the erythrocytes and the release of young erythrocytes by the bone marrow. As for the biochemical parameters, there was an increase in M1 only in the result of the measurement of aspartate aminotransferase (AST) and reduction of blood glucose. The results showed that physiological, hematological and biochemical changes occurred after the tests in horses, due to the physiological requirements for the equine exercise. The highest changes were observed in the physiological results, as well as the VCM, AST, LDH, CK and blood glucose of the horses submitted to the tie test in this work.<span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p> Rayssa Ludmila Menegatti, Alexsander Toniazzo de Matos, Jorge Alfonso Morales-Donoso, Cristiane Maria Fernandes de Melo ##submission.copyrightStatement## Fri, 01 Jul 2022 00:00:00 -0600 Human ascariasis, an evolutionary complex relationship between host and parasite <p>La ascariasis es una enfermedad parasitaria que diezma la salud de cientos de miles de seres humanos, especialmente en los países en desarrollo. Sin embargo, la falta de profilaxis adecuada del parásito, asociado con un mayor riesgo de sufrir enfermedades inmunes, es un problema principalmente en los países desarrollados donde la prevalencia del parásito es muy baja. La relación evolutiva y los mecanismos por los cuales el parásito fue capaz de colonizar y establecerse en el huésped humano aún no se han descifrado. Del mismo modo, los mecanismos inmunes (proximales) de respuesta del huésped para eliminar o controlar el parásito no se entienden completamente. La comprensión de estos mecanismos nos permitirá establecer mejores tratamientos médicos, evitando efectos indeseables y más enfocados en el control de la parasitosis, así como para la terapia de estas enfermedades inmunológicas asociadas con la relación huésped-ascárido.<span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p> Mario Baldi, Norberto Baldi ##submission.copyrightStatement## Fri, 01 Jul 2022 00:00:00 -0600 Atherosclerosis in a cockatiel (Nymphicus hollandicus): Case report in Costa Rica <p>A ten-year old female cockatiel (<em>Nymphicus hollandicus</em><span id="transmark" style="display: none; width: 0px; height: 0px;"></span>) that suddenly died during the veterinary examination was analyzed through histopathology in the laboratory of the Avian Pathology Diagnostic Unit, School of Veterinary Medicine, Universidad Nacional. Macroscopic lesions showed thickening of the ascending aorta and of the aortic bifurcation, multiple nodules and tortuous vessels. Atherosclerotic lesions with variable severity were also observed. The present case report provides a description and characterization of the histopathological lesions of arteriosclerosis. The available diagnostic methods, preventive measures, and possible treatments against this avian pathology in Costa Rica are mentioned.</p> Beatriz Valverde Rodríguez, Aida Chaves Hernandez ##submission.copyrightStatement## Sun, 05 Jun 2022 00:00:00 -0600
