title: Atypical Chryseobacterium meningosepticum and meningitis and sepsis in newborns and the immunocompromised, Taiwan.
abstract: From 1996 to 1999, 17 culture-documented systemic infections due to novel, atypical strains of Chryseobacterium meningosepticum occurred in two newborns and 15 immunocompromised patients in a medical center in Taiwan. All clinical isolates, which were initially misidentified as Aeromonas salmonicida by an automated bacterial identification system, were resistant to a number of antimicrobial agents. The isolates were characterized as atypical strains of C. meningosepticum by complete biochemical investigation, 16S rRNA gene sequence analysis, cellular fatty acid analysis, and random amplified polymorphic DNA fingerprinting (RAPD). This is the first report of a cluster of atypically variant strains of C. meningosepticum, which may be an emerging pathogen in newborns and the immunocompromised.
