Potential for Transmission of Pseudomonas Aeruginosa and Other Bacterial and Parasitic Infectious Agents by Drosophila sp. (Fruit Flies) as Mechanical Vectors

摘要: Introduction: Drosophila melanogaster , a fruit fly, has for more than 100 years played pivotal role in scientific research, particularly genetics and developmental biology.  However, the just like any other fly may act as mechanical vector aiding transmision of parasitic bacterial infectious agents. This philia not only fruits moist food, but also environments including sinks, toilets, latrines, urinaries, sewages, soaps, sponges, towels, bathooms, mops, plants. The fact that these flies alternate between filthy food suggests they have potential transmiting pathogens such as  Entamoeba histolytica Giardia lamblia,Trichuris trichiura, Ascaris lumbricoides, Salmonella tyhi, Shigella dysenteriae, Vibrio cholera, Escherichia coli, Campylobactor jejuni even, Pseudomonas aeruginosa from to food. Of particular concern  is possible relationship . an opportunistic pathogen, one top three responsible nosocomial infections. Hypotheses: sp. could be There thrives environments, produces fruity odor, two types soluble pigments: fluorescent pigment pyoverdin blue pyocyanin, juicy does hence attracting their vectors. study designed investigate Methodology: D. samples were collected bathrooms, toilets/latrines, kitchens hospital wards using improvised sterilized traps. These versatile traps (plastic containers; with transparent base colored lids) patented grade attractant (a mixture ripe banana paste bread crumbs small amounts ethyl acetate added) readily attracts several species baited then analyzed agents using  culture biochemical tests, concentration techniques (e.g. formal ether), respectively. Determination whether transmit various or not, was achieved by computing proportions 40 sampled areas analyzed. there statistically significant attraction, bait type, color, comparing geometric means number colors type groups. T-test ANOVA used compare difference at significance levels 5%. Results: most commonly isolated P. E. while being S. stercoralis. Candida albicans fungal agent melanogaster. cultures attracted different color did not. Conclusion: probably bacterial, parasitic, pathogens. thus enhancing its transmission. To prevent breeding bushes should cleared, dust bins emptied cleaned regularly, stagnating water drained around our residence hospitals environment.
