Estimation of the Antibiotic Activity against Pseudomonas sppIsolated from Ear Infection

Abstract

Background: An ear infection, can be classified into otitis externs and otitis media, this affects all age groups especially infants and young. This infection associate with pathogenic microorganism type, frequent antibiotic uses, health care and age. The most common pathogenic bacteria of the ear infection are Pseudomonas spp. Antibiotic resistance represents a serious threat to the health of humans. Methods: 48 ear swabs were collected through the use of wooden sticks in a sterile container for the identification of Pseudomonas, Serratiaand Klebsiella species by VITEK 2 system and biochemical tests. The antibiotic susceptibility against these bacterial species was detected through the method of standard disk diffusion on the Moller Hinton agar. Results: Among ear swabs, the positive growth percentage of the pathogenic gram-negative bacteria was 29.166%, and the percentage of Pseudomonas spp. was 57.142%. Males were found to be more susceptible than females with an infection percentage of 57.142%. Conclusion: The antibiotic susceptibility patterns show the azithromycin, gentamycin, piperacillin, ceftriaxone, cefepime, imipenem, ceftriazon, and gentamycin have activity against Pseudomonas spp.
