Nosocomial infections are infections that occur 48-72 hours after hospitalization, especially caused by bacteria, and pose a high risk for patients in the intensive care units (ICUs), including Covid-ICU. This study was aimed to reveal the distribution and antibiotic susceptibility profiles of bacteria isolated from various clinical samples of non-Covid-ICU and Covid-ICU patients. Bacterial strains isolated from ICUs patients in Kastamonu Training and Research Hospital between March 2020 and October 2020 were included in this study. The identification of the strains was carried out using the Vitek 2 compact automated system (BioMerieux, France) as well as standard microbiological methods. Antibiotic susceptibility tests were studied using the Vitek 2 automated system and the results were interpreted based on the European Committee for Antimicrobial Susceptibility Tests (EUCAST) guideline. There were 302 patients in the non-Covid-ICU and 440 patients in the Covid-ICU. A total of 470 strains, 370 from non-Covid-ICU and 100 from Covid-ICU, were isolated. Acinetobacter spp was the most frequently isolated species for both ICUs. Acinetobacter spp isolated from non-Covid-ICU had higher resistance rates to meropenem (p= 0.043), ceftazidime (p= 0.014), and levofloxacin (p= <0.001) antibiotics than strains from Covid-ICU. Antibiotic susceptibility profiles of other strains were similar for both ICUs. As a result, the incidence of nosocomial infections in Covid-ICU patients was lower than in non-Covid-ICUs patients. Health personnel working in Covid-ICU may have played an important role in this, as they were more careful about using personal protective equipment and complying with hygiene rules. However, antibiotic resistance continues to be a serious problem in ICUs, including Covid-ICU.
