| detection and isolation of highly pathogenic h5n1 avian influenza a viruses from blow flies collected in the vicinity of an infected poultry farm in kyoto, japan, 2004. | during the outbreak of highly pathogenic avian influenza that occurred in tamba town, kyoto prefecture in 2004, a total of 926 flies were collected from six sites within a radius of 2.3 km from the poultry farm. the h5 influenza a virus genes were detected from the intestinal organs, crop, and gut of the two blow fly species, calliphora nigribarbis and aldrichina grahami, by reverse transcription-polymerase chain reaction for the matrix protein (m) and hemagglutinin (ha) genes. the ha gene encod ... | 2006 | 16896143 |
| dispersal of a blow fly, calliphora nigribarbis, in relation to the dissemination of highly pathogenic avian influenza virus. | a mark-release-recapture study of the dispersal ability of blow flies, calliphora nigribarbis, was conducted in ikumo-naka, ato town, yamaguchi prefecture, japan in december 2004. a location where a fatal avian influenza outbreak had occurred 1 year previously was selected for the present study. a total of 3,884 c. nigribarbis were collected, 1,915 of which were marked and released from 4 different collection sites during 2 successive days. the recapture rate of the released c. nigribarbis range ... | 2009 | 19628908 |
| survival of avian h5n1 influenza a viruses in calliphora nigribarbis (diptera: calliphoridae). | in a previous study, the highly pathogenic avian influenza (hpai) h5n1 viruses were isolated from blow flies collected at the tamba town of kyoto prefecture during the outbreak period in march 2004. in this study, we carried out virus exposure experiments to investigate whether the h5n1 virus would survive in a blow fly, calliphora nigribarbis. the virus exposure experiments showed that the h5n1 influenza virus was isolated from the crop and intestine of c. nigribarbis for at least 24 h, and the ... | 2009 | 19645288 |
| potential efficacy of olyset mosquito netting against calliphora nigribarbis (diptera: calliphoridae) invasion into livestock barns. | calliphora nigribarbis vollenhoven is a possible mechanical transmitter of highly pathogenic avian influenza. based on laboratory tests, we evaluated the efficacy of a long-lasting permethrin-treated mosquito netting, known as the olyset net, for the prevention of this species entering livestock barns. flies were trapped in olyset net cages, and two statistics for knockdown and lethal efficacies were obtained. median knockdown time in the cage (kt50) was estimated to be 341 s for females, and me ... | 2012 | 23156179 |
