Aim

This study aim to determine commonest microorganism of chronic suppurative otitis media and their antibacterial susceptibility⁽¹⁾ as in  chronic otitis media Bacterial infection is often a causes of  exacerbation in the clinical course and failure in the treatment. The aim of the study was to determine the incidence and profile of the aerobic bacterial flora in chronic otitis media and   to determine the drug susceptibility of isolated bacteria^(2).         

Material and Method

A total of 75 patients with unilateral or bilateral  active chronic suppurative otitis media attending the OPD Clinic of ENT Dept. from August 2018 to January 2019 were included in the study. All patients were evaluated through detailed history and clinical examination was also done .Patients (males 65, 10 females; mean age 20 - 40 years). Pus sample were collected from the discharging ear(s) with the help of sterile swabs and sent to the hospital laboratory where culture sensitivity studies were done to determine the microbiological profile ^(3).

Results

This study was conducted for 6 months from August 2018 to January 2019. Total 75 samples were studied. Among them, 29 (38.66%) were pure culture and 2 (2.66%) were mixed. Staphylococcus aurerus 16(21%) was the most common isolate, followed by Pseudomonas aeruginosa 13(17%) and other isolated microorganisms 5(6.66%) which included Acinetobacter 2(2.66%), CONS 2(2.66%) and Streptococcus pyogenes 1(1.33%). Drug sensitivity pattern of Staphylococcus aureus showed that Linezolid was active against majority 93.75%, of isolates followed by Vancomycin 81%, Teicoplanin 75%, Tetracycline and Doxycyclin hydrochloride 68%. Pseudomonas aeruginosa was sensitive to Amikacin 100% and Ceftazidime 92%, Meropenem 77% whereas resistant to Imipenem, Ticarcillin, Clavulanic acid, Tobramicin, Piperacillin, tazobactam  in 41% cases ^(3).
