Listeria monocytogenes is an increasingly impoant cause of meningitis in neonates (60 years, and immunocompromised individuals of all ages. Foodborne human listerial infection has been repoed from contaminated coleslaw, milk, soft cheeses, and several types of "ready-to-eat" foods, including delicatessen meat and uncooked hot dogs. Group B streptococcus, or S. agalactiae, was previously responsible for meningitis predominantly in neonates, but it has been repoed with increasing frequency in individuals >50 years of age, paicularly those with underlying diseases.
