Enterococcus faecalis is a type of bacteria commonly found in the intestines of humans and animals. It is part of the normal gut flora, helping with digestion and nutrient absorption. However, under certain conditions, it can cause infections, particularly in individuals with weakened immune systems. This bacterium is known for its ability to resist many antibiotics, making infections difficult to treat. E. faecalis can lead to various health issues, including urinary tract infections, endocarditis, and wound infections. Its presence in clinical settings raises concerns about antibiotic resistance and the need for effective infection control measures.
