Myroides Spp: An Emerging Uro-pathogen in Catheterized Patient Isolated in Tertiary Care Hospital, New Delhi: A Case Report

Abstract

Introduction: We are presenting a case report of urinary tract infection caused by an emerging pathogen ( Myroides spp.) in an immunocompetent patient. They are low grade pathogen but can cause serious infections in immunocompromised patients. Background: Myroides spp. were traditionally classified as Flavobacterium spp., which are Gram negative, non-fermentative and non-motile bacteria. Myroides spp. are commonly present in environment, sewage, food and soil. An increasing number of infections such as urinary tract infections, sepsis and skin and soft tissue infections, caused by these microorganisms has been reported. Due to its multidrug resistant nature, it is important to correctly identify Myroides spp. in order to choose the best treatment regimen. Case: A 62yr male resident of Delhi presented to Surgery Emergency Department of our hospital with complaints of recurrent episodes of retention of urine and heaviness in lower abdominal. Patient had history of repeated catheterisation with BPH (Benign Prostate Hypertrophy). Subsequently, urine sample was inoculated on Blood Agar and MacConkey’sAgar and incubated for 24 hours at 37ºC. After the incubation, a pure culture with a colony count of >100,000 CFU/ml of a non-lactose fermenting colony was identified as Myroides spp. The patient was successfully treated with Aztreonam after antibiotic susceptibility testing confirmed its susceptibility. Conclusions: This case report brings to light the importance of a newly emerging atypical multidrug resistant uro-pathogen in an immunocompetent individual.
