Abstract

Background: Ear infection is a health problem amongst all ages globally. The high rate of antibiotic-resistance has thus worsened this problem along-side paucity of data on ear infection in northern Nigeria. The aim of this study is to determine the bacterial isolates and their drug susceptibility patterns from patients who had ear infection. Method: A retrospective study of a reviewed of records of ear swab samples collected at the Medical Laboratory Department of National Ear Care Centre (NECC) from the period of January 2014 to December 2016. Sample were cultured on MacConkey, blood and chocolate agars and subsequent biochemical analyses. Data was analyzed using Statistical software for social sciences simple descriptive statistics and result was presented as tables. Result: A total of 1,415 ear swabs were obtained, 1,117 (78.9%) had bacterial isolates with 298 (21.1%) had no growth. 52.4% were males and 47.6% were females. The age group of (1 to 10) had the highest number of laboratory visits (35.3%). The most common organism isolated are pseudomonas specie (40.0%) staphylococcus aureus (31.8%) and coagulase negative staphylococcus (10.1%). Staphylococcus aureus, coagulase negative staphylococcus, enterobacter specie and diptheroids specie were the most sensitive isolate to antibiotics, while the most susceptible antibiotics were ciprofloxacin, gentamycin, pefloxacin and streptomycin. Conclusion: Children under the age of ten (10) are most affected with ear infections. Pseudomas specie and staphylococcus aureus which are susceptible to fluoroquinolones and aminoglycosides in this study.
