Clostridium perfringens bacteria, previously Clostridium welchii bacteria, are one of the most prevalent causes of food poisoning. According to the Centers for Disease Control and Prevention (CDC), these bacteria cause about 1 million infections in the United States each year. C. perfringens is present on raw meat and poultry, as well as in animal intestines and the environment.
Intrauterine infection caused by Clostridium perfringens is an uncommon occurrence. Septic abortion is the most common cause of intrauterine Clostridium infection, with a reported frequency of 0.5 to 1.0 percent. C. perfringens has been the subject of three published case reports.
