Saccharomyces boulardii and Lactobacillus plantarum are two probiotics often prescribed to patients who have diarrhea and colon inflammation associated with a Clostridium difficile infection, according to WebMD. Lactobacillus is a naturally occurring bacteria found in the stomach and the intestines, while Saccharomyces boulardii is a yeast probiotic, explains UpToDate.
Bifidobacterium bifidum, which is found in some dairy products, also has been shown to help with traveler's diarrhea. Probiotics keep the gastrointestinal tract healthy, explains WebMD. Probiotics are found in fermented foods such as yogurt and in supplement form.
Clostridium difficile is often diagnosed after a patient has taken a course of antibiotics that destroy the flora, or good bacteria, found within the gastrointestinal tract, states UpToDate. Other risk factors for developing a C. difficile infection include taking antacids such as Prevacid and Nexium for extended periods of time, according to the U.S. Department of Health and Human Services.
