Abstract
Background:Otitis media is one among the leading causes of illness in infants and adults,which causes an inflammation in middle ear cleft without any reference to etiology or pathogenesis.Microorganisms change their growth and susceptibility based on the region and climate. Therefore, it is important to analyse microorganisms causing otitis media.
Aim: To evaluateantibiogram of the microorganisms causing otitis media in Karad.
Method:Present cross-sectional study was carried out for 176 patients with otitis media. Pus samples were collected from discharging ears. Microorganisms were isolated and susceptibility testswere performed for each isolate. Data was analysed using Chi-square test and percentages.Significance was tested at p<0.05 level.
Results: Among all 176 swab cultures, 162 cultures showed positive growth. Of which 62.96% belonged to acute suppurative otitis media (ASOM) and 37.04% was chronic suppurative otitis media (CSOM). Purulent (74.53%) and mucopurulent (69.70%) type of discharge was prevalent under ASOM and CSOM, respectively (p<0.001).Staphylococcus aureus (n=51) for ASOM and Pseudomonas aeruginosa (n=31) for CSOM were commonly observed isolates. Pseudomonas aeruginosa was the predominant organism followed by Klebsiella pneumoniae and Staphylococcus aureus.Ciprofloxacin was the most effective antibiotic (68.38%) in case of ASOM while Gentamicin was most effective antibiotic (69.44%) under CSOM.
Conclusion:Majority of the bacterial isolates were multidrug resistant. In this study Pseudomonas aeruginosa was the most dominant organism. Ciprofloxacin and Gentamicin were the most sensitive anti-drugs in ASOM and CSOM, respectively.
