Background : Otitis media(OM)is a common childhood infection.Acute pathogens include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, while chronic cases often involve Pseudomonas aeruginosa and Staphylococcus aureus.Microbiological identification is essential for effective treatment.Methods : Cross-sectional study was conducted at two centers with 143 pediatric patients.Dacron swabs were used for pathogen culture and antibiotic susceptibility testing.The study was conducted at Universiti Kebangsaan Malaysia and Hospital Tengku Ampuan Rahimah, Klang Valley.Results : Staphylococcus aureus(34％)and Pseudomonas aeruginosa(28％)were the most common pathogens.In chronic OM, Pseudomonas aeruginosa predominated(88． 5％) .Both pathogens showed good sensitivity to ofloxacin and ciprofloxacin, with sensitivity rates of 84％-94％.Conclusion : Staphylococcus aureus and Pseudomonas aeruginosa are prevalent in pediatric OM and are sensitive to ofloxacin and ciprofloxacin, making them effective first-and second-line treatments.
