ISOLATION AND IDENTIFICATION OF PSEUDOMONAS AERUGINOSA FROM EAR SAMPLES AND ITS ANTIBIOGRAM ANALYSIS

Abstract

ABSTRACT
Objectives: The aim of this study was to determine the frequency of Pseudomonas aeruginosa in middle and outer
ear and to check the antibiotic susceptibility pattern of commonly used antibiotics.
Material and Methods: In this study a total of 42 samples were found as positive for P. aeruginosa out of 100 and tested
for six antibiotics (cefixime, ciprofloxacin, amikacin, imepenem, gentamicin, aztreonam).
Results: 42 samples out of 100 were found positive for P.aeruginosa. Gender wise distributions were higher for female
as compared to males. 22 samples (52%) were positive for females and for male 20 samples (48%) were found positive.
Antibiotic sensitivity pattern was checked. Pathogen was highly sensitive to Gentamicin 30 (71.4%), followed by
Aztreonam 28(66.6%), Cefixime 22 (52.3%), Imepenem 18(42.8%), amikacin 15(35.5%) and Ciprofloxacin 12(28.5%).
Conclusion: Females were more susceptible to Pseudomonas infections. Isolates of P. aeruginosa from samples
showed highest sensitivity (71.4%) to Gentamicin while maximum resistance was showed to Ciprofloxacin (47.6%).
Key Words: Pseudomonas aeruginosa, ear infections, antibiotics susceptibility
