Emergence of antibiotic resistance in bacteria isolated from tubotympanic type of chronic suppurative otitis media in Chhattisgarh

Background Chronic suppurative otitis media (CSOM) is a common chronic ear disease and a major health problem in developing countries causing deafness and life threatening complications like meningitis and brain abscess. Early and effective treatment based on the knowledge of causative organism and their antibiotic sensitivity is essential for immediate clinical recovery.

Methods Total of 152 clinically diagnosed patients with CSOM safe were enrolled in the study and two swab of the discharge ear were obtained from each patient under aseptic precaution. Microbiological study was done according to standard operative guidelines.

Results Out of 152 patients 93 male and 59 were female, majority of the patient seen below 30 year of age. Most common organism found was Staphylococcus aureus (43.2%) and Pseudomonas aeruginosa (27.9%). Staphylococcus aureus was sensitive to vancomycin (98%) and linezolide (100%) and Pseudomonas aeruginosa was found highly sensitive to Imipenem cilastin (84.85%) and Imipenem (66.7%).

Conclusions In our study gram positive Staphylococcus aureus (43.2%) and gram negative bacilli P. aeuroginosa (27.9%) was the most common organism was found and this P. aeruginosa were hospital acquired infections. We found out high resistant to Cefepime, ceftazidime, ciprofloxacin and levofloxacin and aztreonam.
