ABSTRACT
Objective: Chronic suppurative otitis media is a common infectious disease of worldwide prevalence. This study was conducted to identify the commonest microorganisms involved and their antibiotic sensitivity pattern in patients of CSOM.
Study Design: Descriptive study
Place and Duration of Study: This study was conducted at the Microbiology and ENT Department of Amna Inayat Medical college /Kishwar Fazal Teaching Hospital Sheikhupura from August 2015 to July 2016.
Materials and Methods: A total of 85 patients with unilateral or bilateral ear discharge attending the ENT OPD clinically diagnosed as CSOM were selected for the study. Pus samples were taken and sent to microbiology lab for culture and sensitivity. All data was analyzed using SPSS version 21.0.
Results: Pseudomonas aeruginosa (36.47%) was the most common organism isolated followed by Staphylococcus aureus (20%), Coagulase negative Staphylococci (9.42%), Methicillin resistant Staphylococcus aureus (8.23%), Escherichia coli (7.05%), Klebsiella pneumoniae (7.05%), Proteus spp. (4.71%), Enterobacter cloacae (3.53%), Aspergillus niger (2.35%), and candida species (1.17%). Drug sensitivity pattern of Pseudomonas aeruginosa showed that Imipenem was active against majority (95%) cases followed by Tazobactam and Levofloxacin (88%), Ceftazidime (85%), Ciprofloxacin (80%) and Gentamicin (75%). Pseudomonas showed complete resistance to augmentin. Among Gram positive organisms Staphylococcus aureus was the most common pathogen and drug sensitivity pattern showed that Vancomycin has 100% susceptibility to all the gram-positive pathogens.
Conclusion: Pseudomonas aeruginosa is the most common gram-negative organism isolated from the patients of CSOM and it is highly sensitive to Imipenem. Staphylococcus aureus is the commonest among gram positive organisms and Vancomycin is the most effective drug against gram positive pathogens of CSOM.
Key Words: Chronic suppurative otitis media, bacterial pathogens, antibiotic sensitivity.
