Listeriosis as an obstetric complication in an immunocompromised patient.

We have reported a case of maternal death associated with Listeria monocytogenes septicemia in a woman who was being treated with immunosuppressive drugs for lupus nephritis. This report, coupled with a previous case of L monocytogenes sepsis in a pregnant patient with AIDS, emphasizes that L monocytogenes infection may be an important, unrecognized pathogen in pregnant women with impaired immunity.
