| Abstract: | Fluid accumulation was induced in ligated intestinal loops of both pheasants and chickens injected with crude Clostridium botulinum C2 toxin. Necrosis of the epithelium and lamina propria of the duodenum and jejunum occurred in both species of bird after intraduodenal administration of crude C2 toxin. The severity of such reactions depended upon the dose and the period after administration of C2 toxin up to eight hours, and such reactions were suppressed specifically with rabbit anti-C2 toxin. These results confirm that C2 toxin is one of the causes of diarrhoea in avian botulism. |
