Serological investigations on Aujeszky’s disease virus in farm pigs from Iași County

Abstract

Aujeszky's disease caused by Aujeszky's disease virus (ADV) is one of the most important diseases in swine industry. The infection is almost asymptomatic in older pigs and in adults a latent infection persists lifelong. In this study, we conducted a serological survey of ADV in farm pigs in Iași County. In total, 172 pig serums collected between August and September 2016 were screened for the presence of antibodies against ADV. For the screening was used the ELISA kit Svanovir®PRV-gE-Ab, that can differentiate the vaccinated pigs from the infected ones based on the detection of antibodies against the gE antigen. In all four investigated farms positive animals for ADV antibodies were detected, the overall prevalence registered being 36,62%. Our study is a preliminary investigation underlining the possibility of ADV circulation and persistence in swine farms from Iași County.
