Microbiological Assessment of Gram Negative Bacterial Isolates from Ear, Eye, Nose and Throat among Patients Attending Aresho Advanced Medical Laboratory, Addis Ababa, Ethiopia

Abstract

ENT samples from patients who referred to Arsho Advanced Medical laboratory were isolated for further microbiological assessment. Ninetyone (91) from both male and female patients comprising 42 ear, 21nasal, 1eye and 27 throat swabs respectively were screened between April-2017 to July-2017 and the samples were analyzed using culture technique, direct microscopy and identification of bacteria (Vtek 2 compact). Finding from the study identified twelve species of bacteria i.e Pseudomonas aeruginosa, Proteus mirabilis, Kelebsiella oxytoca, Entrobacter cloacae, Citrobacter koseri, Citrobacter pauclus, Pseudomonas fulorescens, Klebsiella, pneumoniae, Acinetobacter baumanii, E.coli, Lecletciaa decarboxylate and Proteus vulgaris. Proteus mirabilis recorded the highest rates (30%) followed by Klebsiella pneumoniae (20%) which was isolated in ear, and nose swabs, while the least were recorded on Citrobacter koseri Citrobacter pauclus, Pseudomonas fulorescens, Proteus vulgaris, Acinetobacter baumanii E.coli, Lecletciaa decarboxylate, Klebsiella pneumonia (3.3%).
