RESUMEN
Aim and background: Myroides (M.) species are ubiquitous in the environment and cause a variety of infections like urinary tract infections (UTI), sepsis, meningitis, cholecystitis, pneumonia, and soft tissue infections, especially among immunocompromised populations. These are usually resistant to multiple antibiotics. This study aimed to demonstrate the clinical profile, underlying comorbidities, and antimicrobial susceptibility of Myroides isolates obtained from nosocomial UTI cases. Materials and methods: A sudden rise in the isolation of Myroides spp. from the repeated urine samples of admitted patients alerted us to conduct this retrospective observational study. Urine cultures that grew M. species were included in this study. Antibiotic susceptibility was performed and the patient's clinical data was analyzed. Results: A total of 14 Myroides spp. isolates were obtained from urine culture. The maximum number of cases (71.4%) were from the Nephrology ward and ICUs. The average (mean) age of patients was 46 years (range 2-80 years). All patients were catheterized. All isolates were multidrug resistant. Minocycline and doxycycline were the only drugs found effective in this study. Conclusions: Myroides species are emerging rare pathogens that can cause UTI in immunocompromised and catheterized patients. Minocycline may be used for treating such infections.
