ABSTRACT
Introduction: Chronic Suppurative Otitis Media (CSOM) is defined as infection of the middle ear that lasts for more than three months and is accompanied by otorrhoea and tympanic membrane perforation.
Aims: Purpose of the study was to determine the prevalence of microbiological agents in CSOM, associated risk factors and establish antimicrobial resistance pattern of these micro-organisms.
Materials and Methods: The study was conducted after ethical approval by ethical committee in Department of Microbiology, Dr. S. N. Medical College, Jodhpur Rajasthan. Two pus swabs were collected with sterile cotton swabs from CSOM patients attending ENT OPD. Isolation, identification and characterization of bacterial isolate were done by standard phenotypic microbiological procedure.
Observations & Results: Out of 150 cases 137(91.34%) was culture positive and 13 (8.66%) no growth (sterile) was obtained. Peak age of presentation was 11-20 years. Out of 150 cases 58% were males and 42% females. Most of these resides in rural area 53.3% and 46.7% belongs to urban area .Among the 150 cases 134 (89.3%) were unilateral while 16 (10.7%) bilateral CSOM patients. Out of total 78% patients already received antibiotic treatment while remaining 22% patients did not receive any treatment. Bacterial isolates were found to be present in 127 (92.7%) cases and rest 10 (7.3%) was Fungal was isolates.
Pseudomonas aeruginosa showed highest resistance to Ceftazidime and least resistance to imipenem. Staphylococcus aureus showed highest resistance to Methicillin and least resistance to linezolid.
Conclusion: The increasing rate Ceftazidime resistance and MRSA in our study is likely due to misuse of antibiotics and decrease concerns about infections caused by antibiotic resistant bacteria.
Key words: CSOM, Ear discharge, microbial profile, antimicrobial resistance.
