title: A new periparturient disease in Eastern Europe, Clostridium difficile causes postparturient sow losses.
abstract: Postparturient sow losses caused by Clostridium difficile have not been reported in the veterinary literature. Recently in Croatia, in a large outdoor production unit with suboptimal environmental conditions, a sudden increase in postparturient sow mortality was diagnosed. After postpartal application of enrofloxacine to postparturient mastitis metritis agalactia (MMA) suffering sows, diarrhea, respiratory distress, and mortality of these sows were recorded. While 13% of MMA suffering and treated sows died, only 0.4% of the non-treated (no MMA suffering) sows died postpartum. Gross pathology revealed mesocolonic edema, hydrothorax, and ascites. Microscopic examination showed scattered foci of suppuration in the colonic lamina propria and accumulation of neutrophils and fibrin on colonic mucosa. Anaerobic cultures of the colon yielded heavy growth of C. difficile. Enzyme immunoassay revealed C. difficile toxins A and B. C. difficile infections of postparturient MMA suffering sows may be associated with environmental stress, the application of antibiotics, or both. C. difficile infections are an impending danger in Eastern Europe and does not only raise animal welfare issues, but seriously inflict the economical well being of outdoor production units.
