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

ABSTRACT

Introduction: The genus Myroides comprises of Gramnegative, non-motile, and non- fermenting bacteria. It is arare opportunistic pathogen but many recent case reports,however, underscore the pathogenic potential that Myroidesspp. possesses for humans. Immunocompromised patients areat higher risk for Myroides infection. Diabetes, catheterizationand ICU stay may increase the chances of acquiring Myroidesinfection.Material and Methods: Urine specimens collected frominpatients were cultured as per standards. Myroides spp.were identified and sensitivity was performed on VITEK® 2Compact™.Results: A total of 16 Myroides spp. isolates were obtainedin the study period. All the isolates were from catheterizedpatients residing in intensive care units. Eleven (69%) patientswere suffering from diabetes mellitus. Extensive resistancewas seen in antibiotic sensitivity results. Minocycline was100% sensitive.Conclusion: Myroides spp. should be considered amongpathogens in hospitalized, catheterized patients. They couldbe extremely drug resistant. Minocycline is a useful antibioticwhile treating UTI caused by Myroides spp.
