Haemorhagic enterotoxemia by Clostridium perfringens type C and type A in silver foxes.
Type C and type A of C. perfringens were detected in the seat of natural infections in silver foxes characterized by symptoms of haemorrhagic enterotoxemia. In all of the dead foxes characteristic changes were noted in the small intestine and parenchymatous organs. The production of alpha and beta toxins by isolated bacteria was confirmed by the bioassay using white mice and by PCR. The results...
متن کاملClinico-pathological findings of Clostridium perfringens type D enterotoxaemia in goats and its hemolytic activity in different erythrocytes
The present investigation was conducted to study the effects of experimental Clostridium perfringens type D enterotoxaemia in teddy goats. Clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. Gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histol...
متن کاملAnti-idiotypic antibody-induced protection against Clostridium perfringens type D.
A monoclonal antibody (BALB/c mouse) with specificity for a neutralizing epitope on the epsilon-toxin produced by Clostridium perfringens type D was used to raise anti-idiotypic antibodies (anti-Id) in different strains of mice and rabbits. These were purified and used in cross-immunization studies to induce anti-(anti-idiotype). All strains of mice and rabbits immunized with BALB/c-derived ant...
متن کاملNaturally acquired antibodies against Clostridium perfringens epsilon toxin in goats.
Clostridium perfringens type D-producing epsilon toxin is a common cause of death in sheep and goats worldwide. Although anti-epsilon toxin serum antibodies have been detected in healthy non-vaccinated sheep, the information regarding naturally acquired antibodies in ruminants is scanty. The objective of the present report was to characterize the development of naturally acquired antibodies aga...
متن کاملHepatic and renal ultrastructural lesions in experimental Clostridium perfringens type A enterotoxemia in chickens.
Hepatic and renal electron microscopic investigations were carried out in 10 chickens that had experimental intraduodenal infection with Clostridium perfringens Type A. Fourteen days postinfection, there were ultrastructural changes in hepatocytes and renal tubular epithelial cells; these included mitochondrial lesions (swelling, cristolysis, rarefication of the matrix, myelin figures), glycoge...
