    Nov 14, 2014


    A highly pathogenic strain of bird flu has been found in Yasugi, Shimane Prefecture, the Environment Ministry said.

    The H5N8 subtype was detected from two samples of droppings of migratory Bewick?s swans that were collected Nov. 3, the ministry said Thursday.

    The ministry has designated 10 km around the spot as an intensive wild bird monitoring area and was sending an emergency investigation team there...

      Note: this is another find, not in swan droppings in Shimane, but in droppings from a wild duck in CHIBA, an other location.

      Epidemiological comments It was confirmed on 20 November 2014 that 2 fecal samples out of 50 fecal samples from Anatidae (wild birds, species unknown) were positive for H5N8 influenza A virus. The samples had been collected on 18 November 2014 and were subject to virus isolation and RT-PCR. The confirmation tests on the pathogenicity of the virus are conducted by the National Institute of Animal Health (NIAH). A follow-up report on the results will be submitted in a few days.

        TOKYO, November 27 (Sputnik) – A highly pathogenic avian influenza type H5N8 was discovered in the south-western Tottori Prefecture in Japan, Kyodo news agency reported Thursday.
        The virus was detected in the analysis of duck fecal samples taken on November 18, according to the agency.

        Japan's Ministry of the Environment has established a 10-kilometer (6-mile) monitoring zone in the region, where the virus was detected. It is yet unknown if the government is planning to test wild birds for the disease, according to Kyodo.

          Epidemiological comments

          Outbreaks in wild birds
          Case 1: A weakened Grus vipio (white-naped crane) was collected on 23 November 2014 and tested at Kagoshima University. It was confirmed on 29 November 2014 that the bird was infected with H5N8 influenza A virus. The result of gene sequencing indicated that a HA0 cleavage site of the amino acid sequence was consistent with that of highly pathogenic avian influenza virus.

          Case 2: Water collected from roost* of cranes on 1 December 2014 was tested against avian influenza virus. It was confirmed on 6 December 2014 that H5N8 influenza A virus was detected in a sample. The result of gene sequencing indicated that a HA0 cleavage site of the amino acid sequence was consistent with that of highly pathogenic avian influenza virus. *artificial wet paddy in a nationally-designated bird sanctuary in Izumi-shi

          Case 3: A dead Grus monacha (hooded crane) was collected on 7 December 2014 and tested against avian influenza virus. It was confirmed on 10 December 2014 that the bird was infected with H5N8 influenza A virus. The result of gene sequencing indicated that a HA0 cleavage site of the amino acid sequence was consistent with that of highly pathogenic avian influenza virus.
          Outbreak in domestic birds On 15 December 2014, the local veterinary service in Miyazaki Prefecture received a notification from a broiler breeder farm on an increase in the number of dead birds (one bird on 13 December, 12 birds on 14 December and 19 birds on 15 December). The samples were sent to the laboratory of local veterinary service (Miyazaki Livestock Hygiene Centre) and the samples from dead birds were confirmed to be influenza A virus positive by antigen-capture kits. On the same day, the centre started RT-PCR test and confirmed that the subtype was H5 on 16 December 2014 (midnight of 15 December 2014). Stamping-out policy was applied to the affected farm. Destruction of all the susceptible birds in the affected farm (approx. 4,000 birds) was completed in the morning of 16 December 2014. Movement restrictions are imposed on the farms within the radius of 3km of the affected farm. Shipment restrictions are imposed on the farms within the radius of 3-10km of the affected farm. The N-type has not yet been identified.
