Recently a number of insect vectors have been identified as potential carriers of antibiotic resistant bacteria, these vectorsinclude house flies which are considered to be theinsects with the most in close contact with human beings; where they carry human pathogenic bacteria on the external areas of their bodies or in their digestive tracts. An analytical, descriptive cross- sectional study was conducted to examine bacterial contaminants of house flies Musca domestica and determined the resistance of these bacteria against antibiotics that are most commonly used. The study was performed from 20th of December 2016 to 22nd of March in 2017in Al-jalla hospital in the city of Benghazi. A total number of 100 house flies were collected from four places, 25 flies from each one. The body surface of house flies was washed using the sterile normal saline and cultured on MacConkey and blood agar. Antibiotic sensitivity testing was performed by Kirby-Bauer disc diffusion methods on Mueller Hinton agar. The most prevalent types of bacteria wasKlebsiella Pneumonia and Escherichia Coli, in addition to Pseudomonas aeruginosa, Acinetobacter SPP, Proteus mirablis and Enterobacterspp. And a high level of multi-drug resistance pattern of the isolated pathogens was demonstrated. We concluded that the house fly could play a vector role for infections in the hospitals. Environmental control measures of these vectors are required to reduce the risk of infection.
