Chryseobacterium gleum - a novel bacterium species detected in neonatal respiratory tract infections.

We report three patients with early neonatal infections. All patients had respiratory tract involvement with increased inflammation markers. Chryseobacterium gleum was cultured from the stomach content aspirated on arrival at the Neonatal intensive Care Unit and it was identified with the help of a Microflex™ MALDI Biotyper mass spectrometer (Bruker-Daltonik, Fremont, CA). Recovery could be achieved with ciprofloxacin treatment. We consider our cases a possible new clinical presentation of a rare human pathogen.
