Enterobacter cloacae is a type of bacteria commonly found in the environment, including soil, water, and the intestines of humans and animals. It is a member of the Enterobacteriaceae family and can exist as part of the normal gut flora, but it can also cause infections, particularly in individuals with weakened immune systems. This bacterium is known for its ability to develop resistance to antibiotics, making infections difficult to treat. Enterobacter cloacae can lead to various health issues, including urinary tract infections, respiratory infections, and bloodstream infections, especially in hospital settings where vulnerable patients are present.
