Cell structure and metabolism
Enterbacter aerogenes is a gram-negative, rod shaped bacterium that contains flagella surrounding it's outer surface.
E. aerogenes as well as others in its genus are known to be resistant to antibiotics, especially E. aerogenes and E. cloacae
Research shows that two clinical strains of E. aerogenes exhibited phenotypes of multiresistance to β-lactam antibiotics, fluoroquinolones, chloramphenicol, tetracycline, and kanamycin.
Both strains showed a porin pattern different from that of a susceptible strain. They had a drastic reduction in the amount of the major porin but with an apparently conserved normal structure (size and immunogenicity), together with overproduction of two known outer membrane proteins, OmpX and LamB
