Aim: In this study, it was aimed to retrospectively assess the frequency and antibiotic resistance of microorganisms isolated from patients in neonatal intensive care units. Material and Methods The study was conducted in a neonatal intensive care unit and sent to a microbiology laboratory between 1.1.2020 and 12.12.2020. The species and antibiotic susceptibilities were assessed in microorganisms isolated from the various cultures. Results: Infections were detected in 29(%4.7) of the 612 newborn patients. All of them were 8 different pathogens. It consists of 15 (%51.7)male and 14(48.3) female infants by gender. Among them, growth were detected in 6(20.6%) blood cultures ,1(3.4%) tracheal aspirate and 22(75.8%) urine samples. Of the microorganisms isolated, 24(82.8%) were Gram-negative bacteria, and 5 (17.2%) were Gram-positive bacteria; The most commonly isolated microorganisms among gram negative were Escherichia coli(75.9%) and 6(27.3) of them are ESBL( Extended Spectrum Beta-Lactamases) posıtıve. Followed by Klebsiella pneumonia 1 (3.4%), and 1 (3.4%).Klebsiella oxytoca. And gram positive were Staphylococcus haemolyticus 1 (%3.4), Streptococcus acidominimus 1 (%3.4), , Streptococcus mitis1 (%3.4), ,Streptococcus oralis 1 (%3.4), and Streptococcus vestibularis 1 (%3.4),. Respectively. Conclusions To plan effective empiric antibiotic therapy against nosocomial infections in neonatal intensive care unit should have information about the characteristics of their own flora.
