Isolation Of Bacterial From External Auditory Canal Of Children And Their Susceptibility Pattern To Antibiotics

ABSTRACT

The bacterial flora of the external auditory canal of children of Michael Opkara University of Agriculture, Staff School, Umudike, Abia State was investigated. The isolates were obtained using standard bacteriological methods. The media used for the isolation included McConkey agar, nutrient agar, and blood agar. Fifty swabs from the external auditory canal were collected from children under 12years of age, the results revealed that 41 (81%) were positive for bacterial growth while 9(18%) had no growth. The predominant organisms isolated included Staphylococcus aureus (56. 1 %). Staphylococcus epidermidis (26.83%), Streptococcus pneumoniaea (9.75%) and Pseudoinonas aeruginosa (7.32%). Antibiotic susceptibility test revealed that all the isolates were multi-resistant to five or more of the tested antibiotics while the most prevalent organisms namely Staphylococcus aureus and Staphylococcus epiderinidis were susceptible to chloraniphenicol. erythrornycin, penicillin, and ciprofiaxin. All the isolates were almost resistant to ampicillin (except Streptococcus pneumoniaea) and pefloxacine.
