[The role of amniocentesis in the management of chorioamnionitis with Listeria monocytogene].

Listeriosis is prevalent in pregnant women. Associated morbidity includes miscarriage, chorioamnionitis, intrauterine and neonatal death. Maternal symptoms are not specific and the diagnosis is difficult with a high rate of false-negative microbiology results. We report here the case a patient who developed a chorioamnionitis at 31 weeks gestation. Diagnosis was established by examination of the amniotic fluid. We report a case of Literiosis in pregnancy diagnosed by direct examination of amniotic fluid obtained by amniocentesis.
