Enterobacter species, particularly Enterobacter cloacae and Enterobacter aerogenes, are important nosocomial(nos.o.comial>>due to hospitalization) pathogens responsible for various infections, including bacteremia, lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections (UTIs), endocarditis, intra-abdominal infections, septic arthritis, osteomyelitis, and ophthalmic infections. Enterobacter species can also cause various community-acquired infections, including UTIs, skin and soft-tissue infections, and wound infections, among others.
Risk factors for nosocomial Enterobacter infections include1- hospitalization of greater than 2 weeks,2- invasive procedures in the past 72 hours,3- treatment with antibiotics in the past 30 days,4- and the presence of a central venous catheter. Specific risk factors for infection with nosocomial multidrug-resistant strains of Enterobacter species include the recent use of broad-spectrum cephalosporins or aminoglycosides and ICU care.
