The study of bacteriological agents of chronic suppurative otitis media - Aerobic culture and evaluation

To study the pattern of CSOM caused by aerobic flora and to determine the antibiotic sensitivity  of the isolated organisms. The ear discharge from one hundred patients with the clinical diagnosis of chronic suppurative otitis media with or without complications was collected and investigated by direct smears and culture methods for isolation of aerobic bacteria and tested for their antibiotic sensitivity. Majority of the cases were of the age 0-20 yrs(71%). Direct smear examination and culture was positive in 93% of cases. Pseudomonas aeruginosa was the most common isolate (40%). The sensitivity pattern for the isolated aerobes was maximum for Amoxiclav and the least for Clindamycin. Microbial Culture and sensitivity helps in appropriate management of CSOM.
