Enterococcus is a type of bacteria that naturally resides in the human intestines as part of the normal gut flora. It supports aspects of gut health, but an overgrowth in stool can signal microbial imbalance or possible infection, especially in individuals with weakened immune systems.
Testing for Enterococcus in stool is important for individuals with gastrointestinal symptoms, such as diarrhea or abdominal pain. It’s also relevant for people with immune-compromised conditions, those undergoing certain medical treatments, or anyone concerned about their gut microbiome balance.
Enterococcus produce acidic metabolic products and antibacterial substances that prevent foreign bacterial colonization in the small intestine (resistance to small intestinal colonization). Low levels promote the occurrence of endogenous infections by disrupting microbial barrier function.
Enterococcus can proliferate due to antibiotic use, dietary changes, or gastrointestinal disorders. Environmental factors and hygiene practices also influence its presence.
