Determination of the Distribution of Bacterial and Parasitic Infection by House Fly in term of Type of Solid Waste Contact in Kerman Province

The aim of this study was to determine the parasitic and bacterial contaminations of houseflies found around various garbages, and to emphasize the necessity of fly control and taking more efficient strategies for garbage disposal. For this purpose, ۸۰۰ houseflies from four garbage sources in the city of Kerman (hospital, urban, fruit & vegetable market, and slaughter house wastes) were collected each month for the period of ۵ conseccutive months. Both the external surface and digestive system of the collected flies were investigated for the presence of bacteria, fungi, protozoa and parasitic worms. Antibiogram test was performed on the collected bacteria. Escherichia coli, Proteus, gram positive cocci (Staphylococcus, Streptococcus), Yeast and mycellial fungi, and amoebae cyst were found in the external surface of all collected flies. In the flies collected from hospital garbages, Klebsiella, Pseudomonos, Giardia cyst, Ascaris and Oxyur ova were also found.. The highest antibiotic resistence was observed against Pseudomonas and the highest sensitivity was observed in Streptococcus. Considering the per capita of hospital garbage production in Iran and its contamination to various types of microorganisms such as viruses transmitted by blood, the appropriate management of hospital garbage disposal in order to prevent the accumulation and multiplication of insects especially houseflies and consequenty the prevention of various diseases and environmental pollution is highly recommended.
