The study aimed to quantify the presence of micotoxins ochratoxine A and toxin T-2 in two common feedstuffs used in poultry diets (yellow corn and soybean meal) from different origins. Samples received for analysis from 2007 to 2011 were included in the study: 139 samples of corn and 64 of soybean meal were analyzed for ochratoxine A and 193 samples of corn and 144 of soybean were analized for toxin T-2. Results showed 66.2 and 67.4% positive samples of maize to ochratoxine A and toxin T-2 respectively, and 71.9 y 88.9% positive samples of soybean for ochratoxine A and toxin T-2 respectively. None of the samples surpassed the accepted limits recommended by the European Commission (2006/576/EC).

El estudio tuvo como objetivo cuantificar la presencia de las micotoxinas ocratoxina A y toxina T-2 en dos ingredientes alimenticios comunes en las dietas avícolas de procedencia diversa. Se analizaron 139 muestras de maíz y 64 de torta de soya para el contenido de ocratoxina A y 193 muestras de maíz y 144 de torta de soya para el contenido de toxina T-2, las mismas que fueron recibidas para análisis entre 2007 y 2011. Los resultados indicaron 66.2 y 67.4% de muestras positivas de maíz para ocratoxina A y toxina T-2, respectivamente. Asimismo, 71.9 y 88.9% muestras positivas de torta de soya para ocratoxina A y toxina T-2, respectivamente. Ninguna muestra llegó a sobrepasar los límites de ocratoxina A y T-2 permitidos, según las recomendaciones de la Comisión Europea (2006/576/EC).

The aim of the study was to identify biovars of Pasteurella multocida and Gallibacterium anatis in poultry with respiratory signs. These bacteria were isolated from samples of secretions and organs of affected broilers, layers and ducks from various poultry farms in the coast and the tropics of Peru. Out of 25 isolates obtained, 13 strains of P. multocida and 12 of G. anatis were identified based on culture characteristics, morphology and biochemical tests (oxidase, catalase, indole, urease). These strains were subjected to micro-well fermentation tests with 10 carbohydrates and one amino acid for typification. Results showed that eight strains of P. multocida corresponded to biovar 1 and the others to biovars 3, 4, 6, 10 and 11, while 11 strains of G. anatis corresponded to biovar haemolytica and one strain to biovar anatis.

El objetivo del presente estudio fue determinar la presencia de factores de virulencia y patrones de resistencia antibiótica en 46 cepas de Escherichia coli aisladas en aves de corral (Pollos de carne - Broiler). Las 46 cepas de Escherichia coli fueron resistentes a ciprofloxacina, enrofloxacina, colistina, amoxicilina, florfenicol, doxiciclina, oxitetraciclina, fosfomicina y sulfatrimetropin. Análisis molecular de REP-PCR y BOXA1R confirmó la presencia de 46 cepas genéticamente diferentes obtenidas a partir de los aislados clínicos. Toxinotipificación mediante PCR para los genes de Toxina Shiga 1 (stx1), Toxina Shiga 2 (stx2) encontró solo la presencia de genes productores de Toxina Shiga 2 en 6 cepas de Escherichia coli (6/46; 13,04 %). El presente estudio constituye uno de los primeros reportes de Escherichia coli productora de shigatoxina 2 en sistemas de producción de pollos...
