Postsurgical Pantoea calida meningitis: a case report

Résumé fourni par la source

INTRODUCTION: Pantoea calida, a recently described environmental Enterobacteriaceae organism, has not yet been associated with human infection. CASE PRESENTATION: We report a case of postoperative meningitis caused by P. calida. After pituitary adenoma resection, a 52-year-old Caucasian woman developed febrile meningitis confirmed by cerebrospinal fluid analysis. P. calida was grown in pure culture from this fluid and was firmly identified with partial rpoB gene sequencing. She was cured by a 14-day course of meropenem. CONCLUSIONS: P. calida must be added to the list of opportunistic Enterobacteriaceae pathogens responsible for postsurgical meningitis. It is easily identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
