Blood samples were collected from 284 pigs, including different productive categories of animals, in abattoirs and herds from Santa Fe, Córdoba and Buenos Aires provinces. Based on the polymerase chain reaction (PCR) amplification of the M. suis 16S rRNA gene, it was estimated a proportion of infected animals of 0.64. Non statistically significant (P>0.1) associations were found between gender, anemia herd history, and breeding conditions with PCR results. On the other hand, significant associations (P<0.1) were found between sanitary status to the infection and geographic origin and productive categories. It was estimated that pigs from Buenos Aires and Córdoba provinces were at higher risk of being PCR positive than pigs from Santa Fe, while piglets and post-weaning pigs were at lower risk of being PCR-positive than other categories. This study suggests that M. suis infection is widespread in the studied pig populations of Argentina.\n Fil: Pereyra, N.B. Universidad Nacional de Rosario. Facultad de Ciencias Veterinarias.

Se recolectaron 284 muestras de sangre de cerdos de diferentes categorías productivas en frigoríficos y granjas de las provincias de Santa Fe, Córdoba y Buenos Aires. Amplificando el gen del ARNr 16S de M. suis a través de la reacción en cadena de la polimerasa (PCR), se calculó un porcentaje de infectados del 64%. Se estimó además que no existía asociación estadísticamente significativa (p>0,1) entre un resultado positivo a la PCR y el sexo del animal muestreado, los antecedentes de anemia en la granja y las condiciones de alojamiento. Contrariamente se encontró asociación significativa (p<0,1) con el origen geográfico y la categoría productiva. Se estimó que los cerdos de Buenos Aires y Córdoba tenían más probabilidades de ser PCR positivos que los de Santa Fe, mientras que los lechones y los cerdos de recría tenían menos riesgo de infectarse que los animales de más edad. Se concluye que el M. suis está ampliamente distribuido en las poblaciones porcinas estudiadas del país. \n application/pdf 1514-6634 (impreso) 1668-3498 (en línea) Mycoplasma suis PCR factores de riesgo cerdos Mycoplasma suis PCR risk factors pigs Argentina spa Universidad de Buenos Aires.
