Title

Microbial and Antimicrobial Susceptibility Patterns from Patients with Chronic Otitis Media in Ardebil

English Abstract

Objective of this study is to identify the commonest microorganisms associated with Chronic Suppurative Otitis Media (CSOM) and their antimicrobial sensitivities. This study was carried out from 2003-2004 at the Department of ear and nose and throat of Ardebil University of medical sciences. Sixty one patients with chronic suppurative otitis media were prospectively studied. They had chronic ear discharge and had not received antibiotics for the previous five days. Also they had no cholesteatoma. Swabs were taken and cultured for bacteria. Bacteriological specimens were processed and identified with standard cultures. Antimicrobial susceptibility of these bacterial isolates was assessed by an agar disc diffusion method. Isolates were tested against 10 antibiotics: The most frequently isolated organism in chronic suppurative otitis media was Staphylococcus aureus 19 (31.15%), followed by Pseudomonas aeruginosa 16 (26.23%) and Proteus sp. 12 (19.67). Fungi accounted for 4 (6.56%) of the isolates. Sensitivity results showed majority of isolates were susceptible to Ciprofloxacin (85.71%) and resistant to Penicillin (84.97%). In conclusion, the in vitro susceptibility results indicate that Ciprofloxacin can be an effective antibiotic in the treatment of active chronic suppurative otitis media.
