<unk>  is a Gram-negative, non-spore-forming bacillus. It is a facultative anaerobe capable of aerobic respiration. It is motile via peritrichous flagella. It is a member of the family of Enterobacteriaceae. The members of this family are the part of the normal flora of human and animal digestive tracts.<unk>  may act as an opportunistic pathogen in a variety of human infections. Brain abscesses have a high rate of mortality and complications, therefore, neonates usually left with severe residual permanent damage. The transmission of<unk>  could be vertical from mother to fetus (local vaginal infection, rupture of the membranes, chorioamniotis may occur between the seventh and 11th day prior to delivery) and other sources can be horizontal nosocomial transmission by asymptomatic nursery staff.
