Enterococcus faecium is a type of bacteria commonly found in the intestines of humans and animals. It is part of the normal gut flora and plays a role in digestion. However, it can also cause infections, particularly in people with weakened immune systems or those in healthcare settings. This bacterium is known for its ability to resist many antibiotics, making infections difficult to treat. Enterococcus faecium can lead to various health issues, including urinary tract infections and endocarditis, which is an infection of the heart's inner lining. Proper hygiene and infection control measures are essential to prevent its spread.
