Objectives: This study sought to determine
causative microorganisms of chronic suppurative
otitis media and their antibacterial susceptibility.
Patients and Methods: Bacteriologic results of middle
ear swabs, agent microorganisms, and their susceptibility
to antibiotics were evaluated in 70 patients (65
males, 5 females; mean age 21.1±1.3 years; range 19
to 25 years) with chronic suppurative otitis media.
Results: No bacteria were isolated in 14% of the
patients. Of 60 patients in whom bacteria were isolated,
the most common bacteria was Pseudomonas
aeruginosa (23%), followed by Staphylococcus aureus
(18%), and Proteus spp. (17%). P. aeruginosa strains
were susceptible to ceftazidime and imipenem (100%),
ciprofloxacin (92%), and amikacin and gentamycin
(85%); S. aureus strains were susceptible to methicillin
and vancomycin (100%), ciprofloxacin (91%), sulbactam-
ampicillin (73%), and gentamycin and trimethoprim-
sulfamethoxazole (63%). Proteus strains were
susceptible to ciprofloxacin (100%), ceftazidime (90%),
and imipenem and gentamycin (70%).
Conclusion: Appropriate knowledge of antibacterial
susceptibility of microorganisms will contribute to
rational antibiotic usage and the success of treatment
for chronic suppurative otitis media.
