Increased recognition of Chryseobacterium species as an emerging cause of nosocomial urinary tract infection following introduction of matrix-assisted laser desorption/ionisation-time of flight for bacterial identification

Harsimran Kaur, Balvinder Mohan, Vinaykumar Hallur, Atul Raj, Madhunarayana Basude, Ravimohan S Mavuduru, Neelam TanejaIndian Journal of Medical Microbiology 2017 35(4):610-616Chryseobacterium species are rarely reported as aetiological agents of nosocomial urinary tract infection. Here, we evaluated the clinical significance of 19 isolates of Chryseobacterium species (15 Chryseobacterium indologenes and 4 Chryseobacterium gleum; identified by matrix-assisted laser desorption/ionisation-time of flight [MALDI-TOF]) obtained from urine or percutaneous nephrostomy drainage of 16 patients with urological complaints. The strains possessed drug resistance to multiple antibiotics. 14 isolates showed the presence of carbapenemases. Both MALDI-TOF and repetitive sequence-based-polymerase chain reaction grouped them into three clusters (Kappa 1.000). They may colonise the urinary tract acting as a reservoir for dissemination of drug resistance within hospital environment.
