Fig. 2From: Sensitive quantification of Clostridium perfringens in human feces by quantitative real-time PCR targeting alpha-toxin and enterotoxin genesQuantitative detection of C. perfringens spiked in human feces by a 16S rRNA gene-specific, b plc-specific, and c cpe-specific qPCR assays with or without Ampdirect® Plus buffer. Strain ATCC 13124T was used as reference for 16S rRNA gene- and plc-specific assays, and ATCC 12917 was used for cpe-specific assayBack to article page
