Effects of Bile Acids and Nisin on the Production of Enterotoxin by Clostridium perfringens in a Nutrient-Rich Medium

Figure 3

Representative results of the fold change in the transcription of sporulation-related genes from C. perfringens SM101 grown in BHI in the presence of bile acids (lined bars) or nisin (dotted bars) after 3.5 h of incubation in comparison with transcription of these genes in bacteria grown in BHI alone. Samples taken at 2 and 5 h also showed upregulation of the same genes.
