'''''Clostridium chauvoei''''' is an [[Anaerobic organism|anaerobic]], [[Motility|motile]], [[Gram-positive bacterium]]. In cattle and sheep, a severe infection causes [[Blackleg (disease)|blackleg]]. Clostridial diseases are considered soil-borne diseases and Clostridium chauvoei, specifically, is known to cause blackleg disease in humans and animals. As it is considered a soil-borne disease, scientists have found a correlation between flooding and the amount of bacteria found in the soil - the spores are redistributed to then contaminate soils, pastures, and water. A study conducted in Taiwan sought to test this correlation by using nucleic acid to extract Clostridium chauvoei from the soil before and after flooding. For the first time, there is evidence to show that the environmental distribution of Clostridium chauvoei is increased after flooding.<ref>{{cite journal|last1=Huang|first1=Shr-Wei|last2=Chan|first2=Jacky Peng-Wen|last3=Shia|first3=Wei-Yau|last4=Shyu|first4=Chin-Lin|last5=Tung|first5=Kwon-Chung|last6=Wang|first6=Chi-Young|title=The Utilization of a Commercial Soil Nucleic Acid Extraction Kit and PCR for the Detection of Clostridium tetanus and Clostridium chauvoei on Farms after Flooding in Taiwan|journal=Journal of Veterinary Medical Science|date=April 2013|volume=75|issue=4|pages=489–495|doi=10.1292/jvms.12-0271|doi-access=free}}</ref> it is named after [[Auguste Chauveau]] who was a French bacteriologist and veterinarian.<ref>[https://lpsn.dsmz.de/genus/clostridium lpsn.dsmz.de, list of prokaryotic names with standing nomenclature].</ref>

Clostridium chauvoei is an anaerobic, motile, Gram-positive bacterium. It is a soil-borne pathogen that can cause blackleg in cattle and sheep. It is named after Auguste Chauveau, a French bacteriologist and veterinarian.[1]

It is mainly considered to be an veterinary pathogen, but at least two severe cases of human infection have been reported.[2][3] Indigenous knowledge from Fula people in Cameroon and Maasai people in Tanzania suggest that zoonotic infection with C. chauvoei may be common among pastoralists.[4] However, these reports may also be due to infection with other Clostridium strains that can cause blackleg, such as C. septicum.[3]

A study conducted in Taiwan found a correlation between flooding and how often C. chauvoei was found in soil samples. This is attributed to flood waters dispersing the bacteria throughout the environment.[5]
