Obstructive Uropathy Caused by Chryseobacterium indologenes: A Case Series from University Hospital, Uttar Pradesh, India

Abstract

Chryseobacterium spp., is non motile, non fermenter, Gram Negative Bacillus (GNB) showing enzymatic activity of catalase, oxidase, and indole production. Chryseobacterium spp. are found widely in the soil and aquatic milieu. It is also capable of surviving in chlorinated water, which can be attributed to the spread of infection in hospital settings hosting profusely immunosuppressed individuals. Newer diagnostic modalities like Matrix-Assisted Laser Desorption Ionisation-Time Of Flight-Mass Spectrometry (MALDI-TOF-MS) and Vitek-2 facilitate early identification and treatment can alleviate the infections caused by them. Present series discusses three cases of Chryseobacterium indologenes (C. indologenes) Urinary Tract Infection (UTI) Case 1- was a 61-year-old hypertensive and diabetic male patient diagnosed with renal failure with pyelonephritis. Case 2- was a female patient of 64-yearold with left upper ureteric calculus. Case 3- was a 31-year-old male patient having left mid ureteric calculus. All the patients were catheterised with a urinary catheter and developed UTI by C. indologenes. C. indologenes infection in UTI patients is uncommon but these cases of complicated UTIs demonstrate C. indologenes as a potential cause of UTI in hospitalised patients using invasive equipment like urinary catheters. As the organism was Multidrug-Resistant (MDR), appropriate antibiotic treatment and accurate identification can alleviate infection by this organism.
