Aerobacter aerogenes

Aerobacter aerogenes is a species of bacteria that is now more commonly referred to as Enterobacter aerogenes. This bacterium is a Gram-negative, rod-shaped, facultatively anaerobic member of the Enterobacteriaceae family. It is found in the human gastrointestinal tract and is an opportunistic pathogen, meaning it can cause disease under certain conditions.

Characteristics

Aerobacter aerogenes is a motile bacterium, possessing peritrichous flagella which allow it to move in liquid environments. It is capable of fermenting carbohydrates, producing acid and gas as byproducts. The bacterium is also capable of reducing nitrate to nitrite.

Pathogenicity

While Aerobacter aerogenes is a normal part of the human gut flora, it can become pathogenic in immunocompromised individuals or when it enters other parts of the body. It is a common cause of hospital-acquired infections, including urinary tract infections, respiratory tract infections, and bacteremia. The bacterium is resistant to many common antibiotics, making infections difficult to treat.

Treatment

Treatment of Aerobacter aerogenes infections typically involves the use of antibiotics to which the bacterium is susceptible. However, the bacterium's resistance to many common antibiotics can make treatment challenging. In cases of severe infection, hospitalization and supportive care may be necessary.
