The Potential Risk of Infectious Disease Dissemination Via Artificial Insemination in Swine

Artificial insemination (AI) is one of the most widely used assisted reproductive technologies in swine. To maintain a healthy semen trade, it is crucial that diligence be given to managing and minimizing the chance of extended semen playing an epidemiological role in the transmission of infectious disease. In swine, pathogens of primary importance, which may be transmitted through semen include Aujeszky's disease, brucellosis, chlamydophilosis, porcine circovirus type 2, classical swine fever, Japanese encephalitis, leptospirosis, parvovirus, porcine reproductive and respiratory syndrome, rubulavirus, foot-and-mouth disease and swine vesicular disease. This paper will summarise the current state of knowledge pertaining to these pathogens in relation to swine AI.
