LABUSCAGNE, Annemarie; SPENCER, B. Tom; PICARD, Jackie A. and WILLIAMS, Mark C.. An investigation to determine the cause of haemorrhagic enteritis in commercial pig grower units in the northern parts of South Africa. J. S. Afr. Vet. Assoc. [online]. 2012, vol.83, n.1, pp.59-65. ISSN 2224-9435.
Necropsies were performed on 36 grower pigs that died peracutely on farms in the northern parts of South Africa. All these pigs were suffering from haemorrhagic enteritis and suspected toxaemia. Samples of the duodenum, jejunum and ileum were taken for histopathological examination and a section of ileum was collected for microbiological examination from each animal. Histological lesions characteristic of enterotoxigenic Clostridium infection were found. Large, Gram-positive bacilli were sometimes abundant in sections and mucosal smears of the intestine. However, only 40% of the cultures were positive for Clostridium perfringens.
