Potent Bile Acid Microbial Metabolites Modulate Clostridium perfringens Virulence

Pathogens, 2023
Clostridium perfringens is a versatile pathogen, inducing diseases in the skin, intestine (such as chicken necrotic enteritis (NE)), and other organs. The classical sign of NE is the foul smell gas in the ballooned small intestine.
