Popis: One hundred ear swabs were collected from patients attending Hawija General Hospital, Azadi Teaching Hospital, and outpatient clinics in Kirkuk Governorate, for ages ranging between 2-45 years, During the period from October 27, 2022 to January 3, 2023. The results showed that 91 (91%) of samples have positive growth on MacConkey , mannitol and blood agar. While the remaining samples 9 (9%) had no growth. The samples that showed positive bacterial growth were identified as 139 isolates. The number of Gram positive isolates was 91, a rate of 65.5%, while the number of negative isolates was 48, a rate of 34.5%. The isolates were diagnosed using routine biochemical tests, and the diagnosis was confirmed by Vitek2 compact system device. The percentage of isolated bacterial species were Staphylococcus aureus by 34.53%, Staphylococcus epidermidis by 22.30%, Proteus mirabilis by 8.63%, Morganella morganii by 6.47%, Enterobacter sakazakii by 6.47%, Staphylococcus saprophyticus by 4.32%, E.coli by 3.60%, Klebsiella pneumonia by 3.60% And each of Kocuria kristinae, Proteus vulgaris, Comamonas testosterone by 2.88%, and Staphylococcus lentus by 1.44%.The results of the sensitivity test to ten types of antibiotics, namely Amikacin, Ceftazidime, Nitrofurantion, Imipenem, Azithromycin, Tetracycline, Cefotaxime, Tobramycin, Ofloxacin, Oxacillin, showed that all isolates were 100% resistant to the antibiotics Cetazidime and Cefotaxime, while they showed varying resistance to the rest of the antibiotics. Antibiotics: All isolates showed 100% sensitivity to Anti- imipenem.
