Viruses in boar semen: detection and clinical as well as epidemiological consequences regarding disease transmission by artificial insemination.
Theriogenology, 2005, Volume 63, N°2, 556-572
The potential role of semen in the transmission of the viruses responsible for the major pig diseases is reviewed: foot-and-mouth disease and swine vesicular disease viruses, classical swine fever virus, Aujeszky's disease virus, porcine reproductive and respiratory syndrome virus, porcine circovirus type 2, parvovirus, Japanese B-encephalitis virus, influenza and transmissible gastro-enteritis (TGE) viruses, African swine fever virus, blue eye disease virus. The risks of transmission of viruses via semen may be associated with heavy epidemiological and economic consequences and should not be minimized. Testing animals prior to their introduction into artificial insemination (AI) centers, during quarantine, and then on a regular basis is a necessary routine measure. In relation to the emergence of new diseases such as PRRS and PMWS, artificial insemination centers should be able to provide clear sanitary guarantees to breeders. To do so, a four-category classification system for viruses is proposed, in base of scientific demonstration of the risk of their transmission via semen, the sanitary status of the country regarding the related disease and the actual sanitary risk for AI.
