Genetic characterization and phylogenetic analysis of Clostridium chauvoei isolated from Hanwoo in Jeonbuk

Isolation and Characterization of Clostridium chauvoei Strains Isolated from Cases of Blackleg in Cattle in Iran

Characterization of Clostridium chauvoei strains isolated from an outbreak of blackleg in Iran

Genetic and functional characterization of the NanA sialidase from Clostridium chauvoei

Clostridium chauvoei is the causative agent of blackleg, a wide spread serious infection of cattle and sheep with high mortality. In this study we have analyzed the sialidase activity of the NanA protein of C. chauvoei and cloned the sialidase gene nanA. Sialidase is encoded as a precursor protein of 722 amino acids with a 26 amino acid signal peptide. The mature sialidase has a calculated mole...

Genetic and phylogenetic analysis of the ribonucleoprotein complex genes of H9N2 avian influenza viruses isolated from commercial poultry in Iran

BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) has been isolated in multiple avian species inmany European, Asian, African and American countries. Sincethe first outbreak of H9N2 virus in Iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. Several amino acids in thevirus ribonucleoprotein (RNP) complex includi...

Complexity of toxins from Clostridium septicum and Clostridium chauvoei.

Production of toxins by Clostridium septicum and Clostridium chauvoei has been the subject of many conflicting reports. Roux and Chamberland (1887) first noted that 3 to 4 day filtrates were antigenic; conferring on guinea pigs an immunity against infection with viable organisms. Production of a lethal toxin by C. septicum was however, demonstrated by Leclainche (1898) and Leclainche and Morel ...
