A Case Western Reserve University School of Medicine-led team of international researchers has for the first time identified a fungus as a key factor in the development of Crohn’s disease. The researchers also linked a new bacterium to the previous bacteria associated with Crohn’s. The groundbreaking findings, published on September 20th in mBio, could lead to potential new treatments and ultimately, cures for the debilitating inflammatory bowel disease, which causes severe abdominal pain, diarrhea, weight loss, and fatigue.

“We already know that bacteria, in addition to genetic and dietary factors, play a major role in causing Crohn’s disease,” said the study’s senior and corresponding author, Mahmoud A Ghannoum, PhD, professor and director of the Center for Medical Mycology at Case Western Reserve and University Hospitals Cleveland Medical Center “Essentially, patients with Crohn’s have abnormal immune responses to these bacteria, which inhabit the intestines of all people. While most researchers focus their investigations on these bacteria, few have examined the role of fungi, which are also present in everyone’s intestines. Our study adds significant new information to understanding why some people develop Crohn’s disease. Equally important, it can result in a new generation of treatments, including medications and probiotics, which hold the potential for making qualitative and quantitative differences in the lives of people suffering from Crohn’s.”

Both bacteria and fungi are microorganisms — infinitesimal forms of life that can only be seen with a microscope. Fungi are eukaryotes: organism whose cells contain a nucleus; they are closer to humans than bacteria, which are prokaryotes: single-celled forms of life with no nucleus. Collectively, the fungal community that inhabits the human body is known as the mycobiome, while the bacteria are called the bacteriome. (Fungi and bacteria are present throughout the body; previously Ghannoum had found that people harbor between nine and 23 fungal species in their mouths.)
