A new study suggests that Clostridioides difficile is responsible for certain colorectal cancers.
According to data gathered by scientists at the Bloomberg Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Kimmel Cancer Center, the bacterial species Clostridioides difficile, or C. diff, which is well known for causing serious diarrheal infections, may also cause colorectal cancer.
The research, which was recently published in the journal Cancer Discovery, may reveal another problematic role for this microbe, which causes over 500,000 infections annually in the United States, many of which are very challenging to treat.
“The uptick of individuals under age 50 being diagnosed with colorectal cancer in recent years has been shocking.
Researchers in the Sears Lab reported several years ago that more than half of colorectal cancer patients had bacterial biofilms — dense colonies of bacteria on the colon surface — while only 10% to 15% of healthy people without tumors had biofilms.
