Characteristics of a strain of Clostridium carnis causing septicaemia in a young infant.

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Pathogenicity and immunogenicity of native and mutant strains of Pasteurella multocida, the causative agents of haemorrhagic septicaemia

Haemorrhagic septicaemia (HS) is a fatal systemic disease of cattle and buffaloes. Some control isachieved with administration of alum-precipitated or oil-adjuvanted killed whole-cell vaccines injectedsubcutaneously. These vaccines, however, provide only short-term immunity and for effective use, theyshould be administered annually. We constructed an aroA attenuated derivative of a Pasteurella ...

Isolation and identification of Clostridium septicum from sheep-dung

  To study the existence of Clostridium septicum as probable agent associated with currently occurrence of black quarter in Urmia area, sheep-dung samples were collected. The bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in Clostridia genus include isolation and biochemical identification were performed. The results showed 28 different types ...

Study on Immunity of an Experimental Oil Adjuvant Haemorrhagic Septicaemia Vaccine in Cattle.

An oil adjuvant vaccine (OAV) was prepared from a local strain of Pasteurella multocida. Strain 6:B was cultured and inactivated by formalin. Bacterial pellet was prepared by centrifugation and subsequently adjuvanted by Montannide oil ISA-70. A dose of prepared vaccine containing 3ml (2mg dry weight/ml) was injected into five calves by IM route. Animals were bled before and at 24, 90, 150, and...

Molecular cloning of Clostridium septicum vaccine strain alpha toxin gene in E. coli

Clostridium septicum a Gram positive anaerobic bacterium produces several toxins including alpha, beta, gamma and delta. C. septicum alpha toxin is lethal and is responsible for a serious disease known as gas gangrene. The aim of the present study was to molecular cloning and sequencing of C. septicum vaccine strain alpha toxin gene. Genomic DNA was extracted using standard phenol and chlorofor...
