  • Evaluation of the physiological, hematological and biochemical profile
           related to the physiology of the exercise of horse submitted the lace

      Abstract: 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.

  • Ascariasis humana, una relación evolutivamente compleja entre el huésped
           y el parásito

    • Authors: Mario Baldi, Norberto Baldi
      Pages: 1 - 16
      Abstract: Ascariasis is a debilitating parasitic disease that has decimated the health of hundreds of thousands of human beings, especially in developing countries. The lack of adequate prophylaxis of the parasite associated with an increased risk of immunological disease is a challenge mainly in developed countries where the prevalence of this parasite is very low. The evolutionary relationship and mechanisms by which the parasite was able to colonize and establish itself in human hosts have not yet been unraveled. In addition, the host immune response mechanisms to eliminate or control the parasite are not fully understood. Understanding these immunological mechanisms (proximates) will allow establishing better medical treatments for diseases related to the positive effects of parasitosis, thus also avoiding the undesirable effects of the parasitosis itself.

  • Evidence of porcine circovirus type 3 (PCV3) in a swine farm in Costa Rica

    • Authors: Laura Chaverri, Fernando Chacón, Evelyn Espinach Roel, Daniel Zeledón
      Pages: 1 - 8
      Abstract: 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.

  • Post mortem findings and bacterial characterization of equine salmonella
           septicemia. A case report

    • Authors: Enid Segura, Ernesto Rojas Sánchez, Carla Murillo, Patricio Razquín, Lohendy Muñoz, Elias Barquero-Calvo, Alejandro Alfaro-Alarcón
      Pages: 1 - 12
      Abstract: 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.

  • Atherosclerosis in a cockatiel (Nymphicus hollandicus): Case report in
           Costa Rica

    • Authors: Beatriz Valverde Rodríguez, Aida Chaves Hernandez
      Pages: 1 - 12
      Abstract: A ten-year old female cockatiel (Nymphicus hollandicus) 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.
