Abstract

Long standing ear infection is very prevalent in developing countries. Appropriate treatment of Chronic otitis media is of utmost importance to avoid various longstanding health issues, including hearing impairment and deficit in social communication.

Purpose of the study: To isolate the causative bacteria and determine the antibiotic sensitivity for the same.

Material and Method: In this study, we included 30 patients that presented to our ENT OPD with complaints of ear discharge. Swab from discharging ear were collected and sent for aerobic culture and susceptibility testing.

Conclusion: Of the total bacterial swabs the organism isolated predominantly were Pseudomonas aeruginosa, followed by Staphylococcus aureus and Proteus spp.

Amongst Gram Positive bacteria, highest resistance was seen for penicillin 10(76%), followed by tetracycline and ampicillin 9(69.2%). Whereas sensitivity was found to amoxicillin in 12(92%), ciprofloxacin in 10(76.9%), azithromycin in 9(69.3%) and Co-trimazole in 8(61.5%). P. aeruginosa showed highest resistance to amoxicillin 15(88.2%) followed by ampicillin 12(70.5%) and showed highest sensitivity to ciprofloxacin 12(70.5%), followed by 10(58.8%) for amikacin and gentamycin. Based on these findings, guided approach for treatment according to the antibiotic sensitivity is necessary.
