Causative organisms of acute suppurative otitis media versus chronic suppurative otitis media

ABSTRACT

One hundred forty patients suffering from acute suppurative otitis media [60 patients, Group I] for the first time with perforation and chronic suppurative otitis media with acute exacerbation [80 patients, Group II] were studied. In group I Streptococcus was isolated from 30 cases and Staph. aureus was isolated from 20 cases. In group II Pseudomonas aeruginosa was isolated from 40 cases, Staph. aureus was isolated from 26 cases and Proteus was isolated from 10 cases. As regards the antibiotic sensitivity test, in group I, Cephalosporin inhibited 18 cases out of 30 cases of Strept. infection and all cases of Staph. aureus infection [20 cases]. In group II quinolone group antibiotics inhibited all cases of Pseudomonas infection [40 cases] and 8 cases out of 20 cases of Proteus infection while cephalosporin inhibited 22 cases out of 26 cases of Staph. aureus infection
