Seroepidemiological survey for Aujeszky's disease virus in herds of the Río Cuarto region (Province of Córdoba, Argentina)

Abstract

1276 sera from 24 pig farms were tested to detect neutralizing antibodies against pseudorabie virus by microtitration serum neutralization test (MTSNT). 92 sera were positive corresponding to the 33,33% of the pig farms studied. When analyzing the breeding systems of the 24 pig farms, 3 were intensive detecting 52 positive sera in 2 of them (65%) while in only 6 of the 21 pig farms with a semi-intensive breeding system the 27.7% were positive. These results provide confirmatory evidence about the prevalence of Aujeszky's disease in our region and also the importance in its diffusion of the breeding system.
