Persistence of Low-Pathogenic Avian Influenza H5N7 and H7N1 Subtypes in House Flies (Diptera: Muscidae)

摘要: Avian influenza caused by avian virus (AIV) has a negative impact on poultry production. Low-pathogenic AIV (LPAIV) is naturally present in wild birds, and the introduction of into domestic assumed to occur through contact with birds human activity, including movement live dead poultry, fomites such as clothing vehicles. At present, possible role insects spread dubious. The objective work was investigate potential transmission LPAIV persistence alimentary tract house flies, Musca domestica L. (Diptera: Muscidae). Flies were fed three concentrations two strains then incubated at different temperatures for up 24 h. flies declined increasing incubation periods. Similarly, increased uptake virus. Persistence infective differed significantly between strains. laboratory experiments study indicate that fly can be carrier AIV.
