Basics
Enterococcus faecalis is a bacterium that is used to treat intestinal complaints. It is a gram-positive, facultatively anaerobic chain coccus bacterium and belongs to the enterococci. The natural habitat of these bacteria is the human intestinal flora. However, if they are found outside the intestine, they can cause illness. They are often used in probiotics, which are intended to contribute to intestinal health. The effect of probiotics is highly controversial among medical experts.
