Enteritis associated with Yersinia pseudotuberculosis infection in a buffalo.
A week after transport a 4 month old buffalo calf developed diarrhoea. Its condition gradually deteriorated and it died. Necropsy revealed acute haemorrhagic enteritis and enlarged mesenteric lymph nodes. Haemorrhages and numerous microabscesses were detected in the lamina propria of the small intestine associated with colonies of Gram negative bacteria. Yersinia pseudotuberculosis was isolated from the small intestine and from mesenteric lymph node. Enteritis caused by Y pseudotuberculosis does not appear to have been reported previously in buffalo in Australia.
