Microbial Flora in Chronic Otitis Media and their susceptibility pattern.
Biomedica Jan ;18:7-10.

Ear swabs from 396 patients suffering from chronic suppurative otitis media were analysed by standard microbiological techniques. The isolates were identified by conventional methodology. The susceptibility to antibiotics was determined by disc diffusion techniques. A total of 332 out of 396 swabs (83.8%) were culture positive. 313 (94.28%) were bacteria And 19 (5.72%) were fungi belonging to the Aspergillus spp. Pseudomonas and Staphylococci were found in 52.077% and 33.227% respectively among six types of bacteria. All Staphylococci were sensitive to Ciprofloxacin. 94.8% of Staphylococci were susceptible to Gentamicin, 94.3% to Arnoxycillin / Clavulanic acid, 92.4% to Cloxacilllin, 63.8% to Erythromycin, 62% to Doxycycline, 58.7% to Cotrimoxazole and 9.1% to Ampicillin. Out of Pseudomonas aeruginosa, 97.2% were susceptible to Ciprofloxacin, 93.6% to Cefoperazone. 90.3% to Ofloxacin, 89.3% to Amikacin, 87.7% to Enoxacin, 72.4% to Ceftazidine and 70.6% to Gentamicin. Staphylococcus was highly sensitive to Ciprofloxacin, Gentamicin and Amoxycillin/Clavulanic acid but resistant to Ampicillin.
