Hepatic 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...
متن کاملHaemorhagic 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 کاملClostridium Perfringens Toxin Types Associated with Meat: Review in Iran
Food poisoning due to Clostridium perfringens (C. perfringens) is a major food health problem, particularly in terms of meat consumption. Due to human’s susceptibility to this pathogen, detection methods and prevention measures should be implemented to reduce its incidence. Several pathogenic strains of C. perfringens have been identified so far. One of the potential concerns about this bacteri...
متن کاملCardiorespiratory effects of isoflurane in Asiatic black bears (Ursus thibetanus) anesthetized with intramuscular medetomidine and zolazepam/tiletamine
The objective of this study was to determine the dose-dependent effects of isoflurane on various cardiovascular parameters and the stable range of isoflurane concentrations in Asiatic black bears (Ursus thibetanus). Seven Asiatic black bears were intramuscularly injected with medetomidine, zolazepam and tiletamine (MZT) to induce anesthesia, and anesthesia was maintained by administering isoflu...
متن کاملOccurrence of Beta2 toxigenic Clostridium perfringens isolates with different toxin types in Iran
Clostridium perfringens is an important cause of enteric diseases in both human and animals. The bacteria produce several toxins which play key roles in the pathogenesis of diseases and are classified into five toxin types, on the basis of the differential production of Alpha, Beta, Epsilon and Iota toxins. In this study a single PCR assay was developed and used for detection of cpb2 gene to id...
