Abstract:
Ear infection has a worldwide prevalence and it is more common problem for both children and adults especially in developing countries. This study was crosses sectional study conducted during the period from August to October in 2015 in Khartoum Ear, Nose and Throat (ENT) Hospital in Khartoum State to determine the frequency and etiology of ear infection.
A total of 100 ear swabs were collected from patients suffering of ear infection, and investigated by conventional microbiological techniques
The mean age of the study population was 25±18 years (age range, 1-75years), and most of them were females 60 (60%) while 40 (40%) were males. A single organism was isolated from 80 patients (80%), more than one organisms were isolated from 16 patients (16%), while no organism isolated from the rest 4 patients (4%).
The predominant bacterial isolates were Pseudomonas aeruginosa 35(31%), followed by Staphylococcus aureus 27(23.9%), Proteus spp 13(11.5%), Klebsiella pneumonae 13(11.5%), Staphylococcus epidermidis 3(2.7%), Staphylococcus saprophyticus 2 (1.8%), Escherichia coli 2(1.8%) and Citrobacter frundii 2(1.8%)
The fungal isolate was Aspergillus niger 9(8%), followed by Aspergillus flavus 4(3.5%) and Candida albicans 3(2.7%).
Of the six antibiotics that are commonly use and available as eardrops or oral antimicrobial at Khartoum ENT Hospital, 45(46.4%) of bacterial isolates was resistant to Amoxayclav, followed by 17(17.5%) Gentamicin, 11(11.3%) Ciprofloxacin and 9(9.3%) Chloramphenicol, while all fungal isolates was sensitive to Clotrimazole and Naftifine hydrochloride.
