A Case of Morganella morganii Meningoencephatitis

Morganella morganii (M. morganii) is a Gram-negative bacillus found in the environment and among normal human intestinal flora. It is a well known cause of urinary tract infections, wound infections, sepsis and other extra-intestinal infections. It also is considered to be an opportunistic pathogen and has been known to occur both in community and nosocomial infections. Most reported cases of severe infections with M. morganii were in patients with some immunological defects. In this paper, we present a rare case in a child who had a residual cavernous hemangioma in the right frontal lobe and suffered from M. morganii meningoencephalitis.
