This study was conducted to generate microorganisms isolated from cultures of ears taken from the patients diagnosed to have chronic otitis media and determine and compare the in vitro effects of different antibiotics on these microorganisms. Between June 2009 and October 2010, 127 ear cultures were taken from 100 patients who applied to the Department of Otolaryngology of Ataturk University Faculty of Medicine Hospital diagnosed to have chronic otitis media in the otolaryngological investigation. Antimicrobial susceptibility of isolated strains was determined by the disc diffusion method according to the CLSI criteria. From the cultures investigated, 277 (6 ferment and 16 fungus) microorganisms were generated. Among the isolated pathogen microorganisms, pseudomonas spp. (24,91%), staphylococcus spp (13,00%), proteus spp. (5,05%) were the three most frequently isolated pathogen agents. 4 Peptococcus spp. (1,44%) and 3 Peptostreptecoccus spp. (1,08%) multiplied and it was observed that there was 2,52% anaerobic reproduction among all microorganisms. It was also seen that Pseudomonas spp. strains were more susceptible to gentamicin (97,1%), imipenem (94,2%), amikacin (84,1%) and ciprofloxacine (78,3%). In the study, vancomycine, teicoplanin, telithromycin and linozolidin were found to be the most effective antibiotics for all staphylococcus. It was seen that proteus spp. strains were more susceptible to gentamicin (92, 9%), ciprofloxacin (%92, 9) and piperacillin (92, 9%). In the antimicrobial treatment required to reach effective outcomes in the treatment of patients with chronic otitis media, it is important to monitor the frequency of effective microorganisms and their rates of resistance to antimicrobial agents.
