BookPublisher: 1991Subject(s): Department of MicrobiologyDDC classification: 0219,T Dissertation note: Clostridial organisms are a part of the normal flora of animal intestine. Under conditions of stress and intestinal stasis bacteria multiply at a very rapid rate and produce intestinal disorders and other acute septicaemic diseases which may result in high mortality and condemnation of carcass and abortion and loss of milk yield in less severe cases.
Faecal samples of 500 sheep of various ages and both sexes, slaughtered at different abattoirs of Lahore were examined during the present study. Clostridial organisms belonging to different species were isolated from 320(64%) ou,t of 500 animals examined. Based upon morphological, colonial and biochemical characteristics these isolates were identified as Clostridium perfrinens 180(36%), Clostridium apcroenes 113(22.6%), Clostridium tetani 10(2%), Clostridium chauvoei 9(1.8%) and Clostridium botulinum 8(1.6%).
Pathogenicity of the isolates was determined in mice and it was observed that 36.25% of the isolates were pathogenic in this species producing acute septicaemic diseases. Out of the different species isolated 11.11% Clostridium chauvoei, 58.33% Clostridiuin prfrinens and 100% Clostridluin tetani were found pathogenic. Pure cultures of isolated organisms were obtained from the livers, tissues and blood of the inoculated mice.
Clostridia are an important group of pathogenic bacteria of veterinary public health significance, further work is recommended for the identification of the toxigenic groups within each species.
