The objective ofthis study was to determine the frequency of Brucella sp in pigs from well managed and poor managed farms ot the Lima valley, Peru. For this purpose, blood samples ofpigs from well managed (n = 222) and poor managed (n = 218) forms were collected at two slanghterhouses. Animals were of both sexes and older than 4 months of age. Antibodies against Brucella sp. were detected by the Rose Bengal test (RB) andComplementFixation (CF) test. The frecuencyof Brucella sp. was4.77 ± 1.81 % in the studied population. The frequency of Brucella sp. in well and poor managed pig farms were2.25 ± 1.47% (5/222) and 7.34± 3.34% (16/218)respectively, whenRB testwas used. However, only 2.75 + 1.76% (6/218) in poor managed farms had antibodies against Brucella sp when using the CF test. None of the animals from well managed farms resulted positive by CF test. This study indicate the presenc...

El presente estudio tuvo como objetivo determinar la frecuencia de Brucella sp. en porcinos procedentes de granjas tecnificadas, que fueron beneficiados en dos mataderos de Lima. con este fin se tomaron muestras de sangre de porcinos de ambos sexos y mayores de cuatro meses, procedentes de granja de crianza tecnificada (n=222) y no tecnificadas (n=218), para la detección de anticuerpos contra Brucella sp. mediante la prueba de Rosa de Bengala como prueba tamiz y Fijación de Complemento (FC) como prueba confirmatoria. El 2.25±1.47% (5/222) y el 7.34±3.34% (16/218) de las muestras procedentes  de crianza tecnificada y no tecnificada, respectivamente tuvieron anticuerpos contra Brucella sp. mediante la prueba de Rosa de Bengala;  pero únicamente el 2.75±1.76% (6/218) de muestras pertenecientes a los animales de crianza no tecnificadas resulto positivo a la prueba de FC. no se detect...
