E
ar infection linked with frequent antibiotic prescription, hearing impairment, severe disability and death is a public health
threat in developing countries. However, there is scarcity of documented data in the study area. Therefore, this study
aimed at determining bacterial etiologic agents and their antimicrobial susceptibility patterns among patients of all age groups
referred to Bahir Dar Regional Health Research Laboratory Center. Retrospective data recorded on culture and antimicrobial
susceptibility profile were retrieved for analysis. Pus swabs from discharging ears collected and processed for aerobic bacteria
culture and susceptibility testing. Of the total 368 pus swab samples processed, 296 (80.4%) were culture positive. Of which, 289
(97.6%) were bacteria and 7 (2.4%) were yeast cells. The proportion of ear infection was higher in males (92.7%) than females
(65 %) (P=0.014). The frequency of ear infection below 21 years of age was 65.2%. The predominant isolate was
Pseudomonas
aeruginosa
(29.7%) followed by
Staphylococcus aureus
(26.3 %) and
Proteus
spp. (21.9%). High level of antimicrobial
resistance rates were observed for amoxicillin/clavulanic acid, ampicillin and penicillin whereas ciprofloxacin, ceftriaxone,
chloramphenicol, cotrimoxazole, gentamicin and amikacin were found effective against the isolated bacteria. Aerobic bacterial
otitis media linked with high levels of resistance against amoxicillin/clavulanic acid and ampicillin is a major health problem
in the study area. Moreover, considerable level of oxacillin resistant
S. aureus
suggests the diffusion of methicillin resistant
S.
aureus
in the community. Therefore, treatment of otitis media in the study area needs to be guided by antibiotic susceptibility
testing of isolates.
