Bacteriological study of chronic suppurative otitis media among patients attending Tikrit Teaching Hospital for the year 2013

Abstract

A total of 63 patients with CSOM were collected in this study during the period from January 2013 to September 2013 at the unit of ENT in Tikrit Teaching Hospital. The results of the bacteriological study of the 63 cases obtained from CSOM patients showed 39 (80.9%) were from children and 24 (38.1%) were from adults. Fifty-one samples (68.6%) were pure cultures had a single organism isolate and 12 samples (19.0%) showed no growth. The peak incidence of COSM among patients was occurred in age group (0-4) years Table (l ).This study indicated that boys 34 (54.0%) showed higher rate of infection than girls 29(46.0%).The ratio of the present study was (1.7:1). The present study showed that the Gve — bacteria were 35(68.6%), Gve+ bacteria werel6 (31.4%). Among the Gve- bacteria Ps. aeruginosa 19(30.2%)was the main causative organisms, while S. aureus 8(12.0%) was being the predominant organism among Gve+ bacteria. .Antimicrobial susceptibility test were done to all bacterial isolates. Ps. aeruginosa isolates showed high sensitive (89.5%) to amikacin and gentamicin, and the high -ensitive rates of S. aureus isolates to same antibiotics were(87.5%) .The isolates of Ps. aeruginosa and S. aureus showed resistance to ciprofloxacin were 6(31.6%), 2(25%) respectively
