Background: Chryseobacterium indologenes is a hospital environment contaminant and can cause healthcare-associated infections. Methods: Patients with C. indologenes infections in a tertiary care center in North India for 6 months were evaluated for susceptibility patterns, comorbidities, mechanical devices, risk factors, and treatment outcomes. The organism was provisionally identified phenotypically, and identification was confirmed by the BD Phoenix automated microbiology system. Minimum inhibitory concentration values of antibiotic susceptibility were determined. Results: A total of 12 isolates of C. indologenes were recovered from 11 patients. Five patients had C. indologenes bloodstream infection (BSI), one had ventilator-associated pneumonia (VAP), and one had both BSI and VAP. In four others, the organism was isolated from the catheterized urinary tract. All VAP and BSI patients were admitted to the Intensive Care Units and mechanically ventilated; all had central lines and history of colistin therapy during the past 15 days. The common underlying risk factors were diabetes, hypertension, and coronary artery disease. Conclusions: C. indologenes infections are increasing because of higher use of carbapenems and colistin, to which it is intrinsically resistant.
