Myroides: An Emerging Pathogen Causing Urinary Tract Infections in Hospitalized Patients

Introduction: The genus Myroides comprises of Gramnegative, non-motile, and nonfermenting bacteria. It is a rare opportunistic pathogen but many recent case reports, however, underscore the pathogenic potential that Myroides spp. possesses for humans. Immunocompromised patients are at higher risk for Myroides infection. Diabetes, catheterization and ICU stay may increase the chances of acquiring Myroides infection. Material and Methods: Urine specimens collected from inpatients were cultured as per standards. Myroides spp. were identified and sensitivity was performed on VITEK® 2 CompactTM. Results: A total of 16 Myroides spp. isolates were obtained in the study period. All the isolates were from catheterized patients residing in intensive care units. Eleven (69%) patients were suffering from diabetes mellitus. Extensive resistance was seen in antibiotic sensitivity results. Minocycline was 100% sensitive. Conclusion: Myroides spp. should be considered among pathogens in hospitalized, catheterized patients. They could be extremely drug resistant. Minocycline is a useful antibiotic while treating UTI caused by Myroides spp.
