| Abstract | ||||
| The microbial flora associated with the housefly, Musca domestica were isolated and their influence on some biological parameters of the fly was studied. The microbial flora isolation was carried out by using different selective and non-selective media. The examination of the housefly gut revealed a heavy and diverse microbial flora, these were : Enteric bacteria (Eschericia coli, Salmonella sp., Shigella sp., Pseudomonuas sp., Klebsiella sp., Proteus sp., Serratia sp.); Cocci form bacteria (Haemoltic Staphylococci and Streptococci, non-haemolytic Staphylococci and Streptococci) and Bacillus sp. Actinomycetec, yeasts and filamentous fungi were isolated only from external surface of the fly. Aposymbiotic (the gut-bacterial free) flies were obtained by feeding female flies on norofloxacine antibiotic. Hatchability, larval and pupal mortality, pupation and adult emergence were affected by elimination of bacteria from the fly gut. It was concluded that gut bacteria of the housefly are not pathogenic but their association might be mutual or even symbiotic. | ||||
