The liver blood chemical profile of the American crocodile (Crocodylus acutus) raised in captivity in the northern region of Peru was determined. Sixty crocodiles were sampled from a population of 255 animals belonging to the Zoocriadero del Centro de Acuicultura La Tuna Carranza, part of the National Fisheries Development Fund (FONDEPES) located in the region of Tumbes, Peru. The animals were classified as young (n=24), subadults (n=27) and adults (n=9). A blood sample (6 ml) was taken from each animal by puncturing the post-occipital venous sinus while animals were under physical restraint. Serum was separated by centrifugation and concentration of each enzyme was measured by spectrophotometry. Variables studied were alanine aminotransferase (ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, indirect bilirubin, total protein and alb...

The objective of the present study was to evaluate the kinetic of antibodies againstthe Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) in 30 of a group of200 pigs in a commercial farm in Lima, Peru. Blood samples were collected at 32, 61 and 135days of age for detecting antibodies against PRRSV by indirect ELISA. In addition, the occurrence of respiratory clinical signs was daily recorded in the total group of 200animals including the 30 animals of the study. The 26.7% (8/30) of pigs had antibodiesagainst PRRSV at 32 days of age and only one at 61 days of age, while 96.7% (29/30) hadantibodies against PRRSV at 136 days of age with S/P values between 0.4 and 2.0. Nonrespiratory problems were recorded. The presence of antibodies and age of animals wasstatistically associated (p<0.05).

El objetivo del presente estudio fue determinar la cinética de anticuerpos contra el virus del Síndrome Reproductivo y Respiratorio Porcino (VPRRS) en 30 animales de un lote de 200 de una granja porcina tecnificada de Lima. Se recolectaron muestras de sangre en tres periodos consecutivos a los 32, 61 y 136 días de edad para la determinación de anticuerpos contra el VPRRS mediante la prueba de ELISA indirecta. Adicionalmente, el lote de los 200 animales, incluidos los 30 animales experimentales, fue observado diariamente durante el tiempo que duró el estudio en busca de problemas respiratorios. El 26.7% (8/30) de las muestras de los lechones a los 32 días de edad tuvieron anticuerpos contra el VPRRS, así como una sola muestra a los 61 días de edad, mientras que el 96.7% (29/30) a los 136 días de edad presentaron anticuerpos contra el VPRRS con valores M/P entre 0.4 a 2.0.
