[Neonatal listeriosis and postnatal contamination. A new case]. / Listériose néonatale et contamination post-natale. Une nouvelle observation.

Four cases of neonatal listeriosis issued from the same maternity during the period of ten days are reported in this paper. Three newborns suffered from a delayed listeriosis meningitic form with complete recovery. The fourth newborn suffered from early septicemic form and died. This is a new observation of post-natal cross infection with listeria monocytogenes in the same maternity. The reported cases remain rare up to now, although this is a classic notion.
