Study associates gut fungi to intestinal inflammation in Crohn's disease patients

Researchers at Case Western Reserve University have revealed that new treatment options for Crohn's disease patients may be on the horizon thanks to the research linking a common fungal pathogen to inflammatory bowel disease. Their findings were featured in the study, ‘Candida tropicalis Infection Modulates the Gut Microbiome and Confers Enhanced Susceptibility to Colitis in Mice’, published Cellular and Molecular Gastroenterology and Hepatology.

The research focuses on the role of the fungus Candida tropicalis (C tropicalis) in triggering chronic inflammation within the gut microbiome. The gut microbiome is a complex ecosystem of fungus and bacteria found within the digestive tract.

They introduced the fungus into animal models and induced colitis (inflammation of only the large intestine) through a chemical compound. The models infected with C. tropicalis showed severe inflammation and significant imbalance of the gut microbiome with changes in bacteria levels.

Researchers say the findings show that this imbalance of fungi and bacteria can create a predisposition to inflammatory bowel disease. Past studies have shown that people with Crohn's disease have higher levels of C. tropicalis when compared to healthy individuals.

"Our findings provide a scientific rationale for eliminating C. tropicalis fungal infection of the gut," said Dr Fabio Cominelli, professor of medicine and pathology and associate dean for program development at the Case Western Reserve School of Medicine. "The next step in our research is to study other fungal organisms within the gut and then antifungal therapies in patients with this devastating condition. Remission is very difficult to obtain in Crohn's disease patients."
