Background: It is known that Acinetobacter is a prominent nosocomial pathogen, particularly in critically ill patients. In addition to antibiotic resistance, the capacity of the organism to persist on surfaces in critical care environments and resistance to desiccation, contribute to the dissemination of these multi drug resistant isolates. Acinetobacter has been linked to various reports of outbreaks of Healthcare Associated Infections (HAIs). We saw a rise in the number of Acinetobacter isolates from the culture samples received from our Medical Intensive Care Unit (MICU). Hence, we investigated the extent of Acinetobacter colonisation in our MICU environment and Health Care Workers (HCWs). Methodology: We screened the MICU environment and HCWs working there as part of a one-day point prevalence study. In total, 65 environmental samples were obtained, including those from patient beds, hospital equipment, high-touch surfaces, and 33 samples from HCWs by collecting hands and oro-pharyneal swabs. We used vancomycin-brain heart infusion broth to selectively recover Gram negative pathogens. Bacterial identification and their antibiograms were performed by standard methods. All Acinetobacter isolates were confirmed by genus level in-house PCR. Results: 80.6% (79/98) of all the samples yielded growth. Acinetobacter was the most common isolate from environment as well as from samples collected from HCWs. The phenotypically identified isolates were confirmed using genus level in-house PCR. Of all the Acinetobacter isolates, 97.1% were multi drug resistant (MDR). In addition, 57.1% were resistant to carbapenems (CRAB). However, highest sensitivity to levofloxacin (77.1%) was observed during the study. Conclusions: ICU environment gets frequently colonized with Acinetobacter baumannii and other Multi-Drug Resistant organisms (MDROs). The HCWs also may carry these organisms and could be source of infection to the ICU patients. Thorough surface disinfection and reinforcement of strict infection prevention and control protocols are necessary from time to time to prevent colonisation of ICU environment by MDROs.
