[Neonatal meningitis caused by Streptococcus mitis].

We report on a female newborn, 37 weeks of gestational age, who - after normal pregnancy and delivery - fell ill with a neonatal meningitis caused by streptococcus mitis. Until now this bacillus has been thought to be apathogen. The disease was cured completely by Penicillin therapy. The infection of a healthy newborn caused by streptococcus mitis, a streptococcus viridans, has not been described before.
