POSTWEANING MULTISYSTEMIC WASTING SYNDROME: EPIDEMIOLOGICAL ISSUES

This review pretended to describe issues related with the Postweaning Multisystemic Was­ting Syndrome (PMWS) especially the epidemiological ones. PMWSbelongs to the Porcine circovirus type 2 associated diseases (PCAVD). Its presentation could be associated with another non identified infectious agent or the interaction between multiple management practices and other infectious diseases. The disease epidemiological pattern hasn’t been clearly understood; PCV2 infection appears to be enzootic while PMWSappears to be epizootic. Both vertical and horizontal transmissions have been reported for PCV2, but the PMWSdevelopment has been related not only with PCV2 infection but also with some other aetiologies. Clinical signs and macroscopic lesions aren’t specific for PMWS. Diagnosis is based on the identification of microscopic lesions in lymphoid organs and the identification of the viral antigen within them. Preventive and control strategies have been focused on specific management practices that improve the environment where animals are kept perse­cuting the reduction of infections rates not only associated with PCV2.
