This study examined 150 ear swab samples from patients with otitis media who consulted at Al-Sadr Teaching Hospital from January to April 2021 in Misan, Iraq. The participants were aged 14–50 years, among which the infection rate was highest in participants aged 14–22 years and lowest in those aged 40–50 years. Subsequently, bacterial isolates were identified based on their morphology in various culture media and using biochemical tests. Six bacterial species were identified, namely Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae, Klebsiella pneumoniae, and Staphylococcus epidermidis. Staphylococcus aureus had the highest infection rate (30%), whereas Staphylococcus epidermidis had the lowest infection rate (8.55%). When the sensitivity of each isolate to antibiotics was determined, Escherichia coli was the most sensitive to trimethoprim (TMP), whereas Pseudomonas aeruginosa was the most resistant to 75% of the tested antibiotics.
