Clinical and Microbiological Analysis of Bloodstream Infections Caused by Chryseobacterium meningosepticum in Nonneonatal Patients

Chryseobacterium meningosepticum bloodstream infections in 11 nonneonatal patients were reported. More than half of the infections were community acquired. PCR assays indicated that the organisms produced extended-spectrum beta-lactamases as well as metallo-beta-lactamases. Genotyping showed diverse fingerprints among the isolates. Six patients survived without appropriate antibiotic treatment. Host factors are the major determinant of the outcomes of C. meningosepticum infections.
