PCR Detection Method ofClostridium scindensandC. hiranonisin Human Fecal Samples

Abstract

Clostridium scindens and C. hiranonis have high bile acid 7α‐dehydroxylating activity. Direct PCR and nested PCR with the specific primers for C. scindens and C. hiranonis were developed and tested for the detection of them in human fecal samples. Nested PCR detected C. scindens in all samples, but direct PCR detected it in 27 of 34 samples. Regarding C. hiranonis, nested PCR detected it in only 18 of 34 samples although nested PCR has a high level of sensitivity. Nested PCR was a specific and sensitive method for the detection of C. scindens and C. hiranonis in fecal samples.
