Overview
Morganella morganii is a Gram-negative facultatively anaerobic bacteria which is part of the normal flora of humans, other mammals, and reptiles. It posesses multiple flagellae, allowing it to "swim" in any direction [Wiki].
While M. morganii is typically a commensal inhabitant of the human gut, it is occasionally associated with nosocomial infections, most often including UTIs and postoperative infections, but also diarrhea, arthritis, colorectal cancer [Cao2022 🕮 ], necrotizing fasciitis, including conditions with a high mortality rate, including meningitis and bacteremia [Lee2006 🕮 ].
Pathogenic factors of M. morganii include its ability to form biofilms [De2016 🕮 ] and the ability to exchange antibiotic-resistant plasmids [Senior1990 🕮 ].
