Myroides species, are reported more frequently as outbreaks in clinics and intensive care units (ICUs). In this study, it is aimed to investigate the epidemic potential, antibiotic resistance profile and risk factors of the M. odoratimimus isolates, are increasingly isolated in the intensive care units (ICUs) of our hospital. Data of patients, whose Myroides spp. were isolated in their clinical specimens, over a five-year period (September 2016-January 2022) were retrospectively analyzed. Identification of bacteria were performed with the Matrix: Assisted Laser Desorption Ionization/Time of Flight-Mass Spectrometer (MALDI-TOF MS) System. The presence of antibiotic resistance genes were analyzed by polymerase chain reaction (PCR) method. Possible clonal association between isolates was investigated the Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR method. 66 isolates were identified as M. odoratimimus and one isolate as M. odoratus. The presence of the blaMUS resistance gene was detected in all M. odoratimimus isolates, while the presence of sul2 in 10 isolates and tetX in 11 isolates was detected. Other resistance genes, including blaTUS, were not detected. Also 2 different clonal association patterns were found in 24 selected isolates by (ERIC)-PCR method.The increase in the immunosuppressive patient population point to the possibility of encountering this agent and other opportunistic pathogens more frequently in the future.
