Lymphocytic-plasmacytic enterocolitis in a cow

A White Park cow with enterocolitis suffered chronic weight loss and diarrhoea. An examination of rectal biopsies revealed an inflammatory infiltrate in the lamina propria, but the aetiology of the condition was not determined despite haematological, bacteriological and parasitological tests. On post mortem examination the inflammatory infiltrate was found throughout the large and small intestine.
