A real-time PCR assay based on the 16S rRNA gene sequence was designed for differentiation of blackleg-causing Clostridium chauvoei and Clostridium septicum, a phylogenetically closely related bacterium responsible for malignant edema. In order to exclude false-negative results, an internal amplification control was included in the assay. A set of three probes, one specific for C. chauvoei, one...

BACKGROUND Clostridium chauvoei causes blackleg, an acute disease associated with high mortality in ruminants. The apparent primary port of entry is oral, during grazing on pasture contaminated by spores. Cases of blackleg can occur year after year on contaminated pastures. A method to determine the prevalence of C. chauvoei spores on pasture would be useful.The standard method for C. chauvoei ...

In all biological systems growth is defined as increase of chemical compounds. Bacteria can achieve to balanced growth if they are growing in a medium, which are completely adapted to it. Clostridium chauvoei, (Clostridium feseri) is an anaerobic, spore forming, motile, and polymorph bacteria, which its size varies from 0.5-1 to 3-8 micron and could be observed as individual bacterium, diplo, a...

AIM Blackleg disease is caused by Clostridium chauvoei in ruminants. Although virulence factors such as C. chauvoei toxin A, sialidase, and flagellin are well characterized, hyaluronidases of C. chauvoei are not characterized. The present study was aimed at cloning and sequence analysis of hyaluronoglucosaminidase (nagH) gene of C. chauvoei. MATERIALS AND METHODS C. chauvoei strain ATCC 10092...

Five groups of ten animals were vaccinated with a combined vaccine containing foot and mouth disease (FMD), rabies, Pasteurella multocida and Clostridium chauvoei antigens and individual component vaccines containing FMD, rabies, Pasteurella multocida and Clostridium chauvoei antigens, respectively. Serological response of the calves was assayed on days 21 and 90 post vaccination. There was no ...

Clostridium chauvoei is the etiological agent of blackleg, a disease of cattle and sheep with high mortality rates, causing severe economic losses in livestock production. Here, we report the draft genome sequence of the virulent C. chauvoei strain JF4335 (2.8 Mbp and 28% G+C content) and the annotation of the genome.

A semi-synthetic culture medium and method are described for the production of a reduced dose Clostridium chauvoei vaccine. The vaccine gave excellent results in guinea-pigs, and 2 injections of 2.0 ml protected cattle against challenge with 2 M.L.D. of a virulent culture for at least 12 months. The suitability of C. chauvoei Strain OP64 as a vaccine strain was confirmed.
