Otitis media (OM) is a major health problem in both developed and developing countries. This study taken to determine the pattern of bacterial isolates in Patients with chronic suppurative otitis media (CSOM) in Latur District, Maharashtra (India). A prospective study carried out in dept. of Microbiology, Govt. Medical College, latur among consenting patients with CSOM attending the ENT department over a period of 10 months. Informed consent was obtained from the patients for this study and microbiological analysis done. A total of 168 patients aged 5-70 years with chronic suppurative otitis media were accounted and total 201 bacteria isolated from ear discharge of 168 paients. In the present study, gram-negative bacteria were the dominant isolates (59.7%) while gram positive bacteria were 81(40.3%) The most Common causal organisms isolated were Pseudomonas aeruginosa 57 (28.35) followed by Staphylococcus aureus 49 (24.37%), Coagulase negative Staphylococcus 26(12.93 %), Klebsiella spp. 23(11.44 %).this study indicates the antibiogram trends of the most predominant bacterial isolates in otitis media. Pseudomonas aeruginosa and S. aureus showed high resistant rate (73.6- 89.4%) to, tetracycline, Erythromycin and amoxicillin.while P.aeruginosa demonstrated 96.5 % sensitivity to norfloxacin and low level of resistance to gentamicin and ciprofloxacin.
