AIM: Study; we aimed the isolation of bacteria and establishment of their susceptibility to antibiotics in patients diagnosed as Chronic Supurative Otitis Media.
METHOD: Sixty-three patients were included in the study. The samples of suppurative material were cultured. Antibiotic susceptibility testing was performed as recommended by Clinical and Laboratory Standards Institute (CLSI) and species was identified.
RESULTS: S.aureus was isolated in 36,5 % of the 63 patients enrolled in the study. For this bacterium, increased rates of resistance to antibiotics penicillin G, ampicillin /sulbactam, gentamicin, amicacin ve TMP/SMX are detected. The other mostly isolated bacteria are P. aeruginosa (32.69%) and E. coli (23.07%) in turn. P. aeruginosa showed increased ratio of resistance to ceftriaxone, cefuroxime, amicacin, gentamicin, ampicillin, TMP/SMX and amoxicillin/clavulanate and also E. coli showed increased rates of resistance to gentamicin, ampicillin, ampicillin /sulbactam and amoxicillin/clavulanate.
CONCLUSION: We consider Chronic Supurative Otitis Media therapy regarding antimicrobial susceptibility rates will be more rational and satisfying.
