Aerobacter aerogenes, also known as Enterobacter aerogenes, is a Gram-negative bacteria commonly found in the environment and in the human gut. It is considered an opportunistic pathogen and can cause infections in immunocompromised patients. There are several synonyms for Aerobacter aerogenes, including Klebsiella mobilis, Klebsiella aerogenes, and Enterobacter cloacae. These bacteria are often resistant to antibiotics and can cause infections such as respiratory infections, urinary tract infections, and sepsis. It is important to properly diagnose and treat infections caused by Aerobacter aerogenes to prevent further spread of the bacteria and potential complications.
