Listeria monocytogenes meningitis in an immunocompetent adult: a case report

Rev Soc Bras Med Trop. 2012 Jun;45(3):410-1. doi: 10.1590/s0037-86822012000300028.


Listeria monocytogenes (L. monocytogenes) is an uncommon cause of bacterial meningitis in immunocompetent adults. Patients with immunosuppression are at increased risk of developing serious invasive diseases, particularly meningitis. We describe a case of meningitis caused by L. monocytogenes in an immunocompetent and previously healthy 34-year-old adult. The patient received treatment with intravenous ampicillin plus amikacin and made a full recovery. L. monocytogenes should be suspected in immunocompetent adults with bacterial meningitis who fail to respond to empirical antibiotic treatment.
