Abstract

Mycobacterium avium (MA) is considered a zoonotic hazard in pork. Herds delivered at slaughter showing gross lesions indicative of a mycobacterial infection, eg. specific abcesses in lymphoreticular tissue, were bacteriologically positive for MA. A risk factor analysis revealing different possible sources of primary infection was carried out at farms supplying these pigs. Also the common farrowing farm supplying the piglets to these farms was taken into account as a possible source of infection. Intradermal tuberculin testing, serology and tissue sampling was carried out on the sows and finishing pigs.

Case study: Tuberculination, serology and bacteriology of sows at a farrowing unit suspected of an infection with Mycobacterium avium

Portland, Maine, USA

Mycobacterium avium (MA) is considered a zoonotic hazard in pork. Herds delivered at slaughter showing gross lesions indicative of a mycobacterial infection, eg. specific abcesses in lymphoreticular tissue, were bacteriologically positive for MA. A risk factor analysis revealing different possible sources of primary infection was carried out at farms supplying these pigs. Also the common farrowing farm supplying the piglets to these farms was taken into account as a possible source of infection. Intradermal tuberculin testing, serology and tissue sampling was carried out on the sows and finishing pigs.
