CDC C. difficile Naming Convention Change (5/19)

By National Nursing Home Quality Improvement Campaign - May 19, 2019

The CDC has begun using Clostridioides difficile instead of Clostridium difficile to refer to the bacterium that commonly causes infectious diarrhea.

The change followed a decision early last year by the Clinical and Laboratory Standards Institute (CLSI).

Given that laboratories and medical publications may be transitioning to the new name, the National Nursing Home Quality Improvement Campaign is making the transition when using the full name. However, the abbreviated form C. Diff is still applicable.
