Although some bacteria are harmful, others can be beneficial to our health. One such bacteria is the probiotic Lactobacillius casei, which can be purchased as a supplement or found in several fermented milk products, including some yogurt. Although L. casei is generally considered safe, do not rely on any probiotic or supplement as treatment without seeking your doctor’s advice for medical issues.

Relieves Crohn's Disease Symptoms

L. casei may offer protection in the intestines of people with Crohn’s disease. In June 2005, the journal “Applied and Environmental Microbiology” published the results of a laboratory study demonstrating that L. casei was able to inhibit the bacteria Escherichia coli from invading and adhering to intestinal cells. According to the journal, more than 36 percent of people with Crohn’s disease have intestinal lesions containing E. coli bacteria.

Relieves Diverticulitis Symptoms

Diverticulitis is a painful condition caused by inflammation in the large intestine or colon. If the inflammation spreads to the peritoneal cavity, causing peritonitis, it can be very serious. A daily dose of probiotics including L. casei helps keep the intestines healthy, controlling diverticulitis and reducing symptoms of the disease, reports the University of Maryland Medical Center.

Reduces Diarrhea

When ingested, the L. casei variant known as Lactobacillus GG can grow and establish colonies in the digestive tract. This can reduce the duration and severity of diarrhea in infants, as well as diarrhea associated with antibiotics, according to a January 2000 in “The American Journal of Gastroenterology.”

Relieves Constipation

L. casei can lessen the severity of chronic constipation, according to the results of a study published in the “Canadian Journal of Gastroenterology” in November 2003. Study participants consuming a beverage containing the L. casei Shirota variant began reporting improvement in their symptoms after about a week. Researchers reported no negative reactions to the beverage and suggested that probiotic beverages can be used along with other treatments for chronic constipation.
