This Include collection of aural swab samples, culturing of samples, identification of causative agents species and antibiotic sensitivity. Gram's negative bacteria were the commonest microorganisms; it comprises (60%). Pseudomonas aeruginosa was common causative agent (19.04%), followed by Staphylococcus aureus (16.7%) and Klebsiella spp. (14.3%). Mixed infection was found in high percent (74%), in which P. aeruginosa and other microorganisms were more common. The antibiotic sensitivity pattern showed that P. aeruginosa was sensitive to Ciprofloxacin, amoxicillin +clavulanic acid and gentamicin, while other is appeared resistant, S. aureus was sensitive to ciprofloxacin, amoxicillin+clavulanic acid, erthomycin, cephalexine and it is resistant to pencillin and ampicillin, klebsiella species were sensitive to ciprofloxacin, amoxicillin +clavulanic acid ,gentamicin,while resistant to tetracycline.
