1st new-flu infection of pigs suspected in Japan
OSAKA, Oct. 20 KYODO
The first possible new-flu infection of pigs in Japan is being investigated as a virus of the H1N1 strain has been detected in a pig at a farm in Osaka Prefecture, the prefectural government and the farm ministry said Tuesday.

Osaka Prefecture May Have First Japan Case of Swine Flu in Pigs


By Masatsugu Horie

Oct. 21 (Bloomberg) -- Pigs in Osaka Prefecture may have contracted swine flu, in what would be the first case of the H1N1 virus being detected in Japanese livestock.

Further tests are being done on samples sent to a research facility near Tokyo, prefectural spokesman Yuji Kihara said by telephone. He declined to specify the location of the suspected infection. The final report is due today.

?I wouldn?t be surprised if the pigs are infected with swine flu because so many humans have the virus,? Kihara said. ?It?s still completely safe to have pork if it?s cooked.?

The U.K., Norway, Ireland, Argentina, Canada and Australia have reported cases of the H1N1 virus in domestic hog herds, according to the Paris-based World Organization for Animal Health. The U.S. Department of Agriculture this week confirmed H1N1 in a pig in Minnesota, and the virus also has been found in turkeys in Chile.

New flu, suspected human infection in pigs from the nation's first
...
October 20

Yomiuri Shimbun

Ministry of Agriculture on September 20 announced that suspected pandemic influenza-infected pigs in pig farms in Osaka Prefecture.

Susceptible to influenza viruses from pigs to people, the ministry said that the first people infected domestic animals from pandemic influenza.

According to the ministry, 16 pigs are fed to a pig farm in Osaka Prefecture, 10頭分tests on samples, tested positive for influenza.

I also studied at the Institute of Animal Health in Tsukuba, Ibaraki Prefecture, raising the possibility of pandemic flu 20 days. To determine whether the new model in 21 days.

This hog farm in 1000 has been raised about the head, and a new case was confirmed, the ministry will be asked to refrain from shipping. The pig farm workers, the new flu infection has not previously been confirmed that there is a possibility of infection from other suppliers out.

The Cabinet Office Food Safety Commission issued a four-month position for pork infected with the new track in order to kill the virus if cooked, can infect people to eat, he said.

Until now, it has been confirmed that the person is infected with pandemic influenza from pigs, the United States, Britain, Australia, Argentina and seven countries.

Ministry of Health "from the people themselves to be infected with swine influenza virus is not uncommon, as is the new flu, and the rise of power is unlikely to toxicity and infection" and that.

Received 20 November 2008/ Accepted 3 February 2009

Due to dual susceptibility to both human and avian influenza A viruses, pigs are believed to be effective intermediate hosts for the spread and production of new viruses with pandemic potential. In early 2008, two swine H5N2 viruses were isolated from our routine swine surveillance in Korea. The sequencing and phylogenetic analysis of surface proteins revealed that the Sw/Korea/C12/08 and Sw/Korea/C13/08 viruses were derived from avian influenza viruses of the Eurasian lineage. However, although the Sw/Korea/C12/08 isolate is an entirely avian-like virus, the Sw/Korea/C13/08 isolate is an avian-swine-like reassortant with the PB2, PA, NP, and M genes coming from a 2006 Korean swine H3N1-like virus. The molecular characterization of the two viruses indicated an absence of significant mutations that could be associated with virulence or binding affinity. However, animal experiments showed that the reassortant Sw/Korea/C13/08 virus was more adapted and was more readily transmitted than the purely avian-like virus in a swine experimental model but not in ferrets. Furthermore, seroprevalence in swine sera from 2006 to 2008 suggested that avian H5 viruses have been infecting swine since 2006. Although there are no known potential clinical implications of the avian-swine reassortant virus for pathogenicity in pigs or other species, including humans, at present, the efficient transmissibility of the swine-adapted H5N2 virus could facilitate virus spread and could be a potential model for pandemic, highly pathogenic avian influenza (e.g., H5N1 and H7N7) virus outbreaks or a pandemic strain itself.

Japan Confirms First Case of Swine Flu in Pigs at Osaka Farm


By Kanoko Matsuyama

Oct. 21 (Bloomberg) -- Pigs in Osaka Prefecture have contracted swine flu, the first case of the H1N1 virus being detected in Japanese livestock.

Operators of the farm in the western prefecture were advised to refrain from moving the pigs until the genetic tests are complete, the Ministry of Agriculture, Forestry and Fisheries said today in a statement on its Web site.

The U.K., Norway, Ireland, Argentina, Canada and Australia have reported cases of the H1N1 virus in domestic hog herds, according to the Paris-based World Organization for Animal Health. The U.S. Department of Agriculture this week confirmed H1N1 in a pig in Minnesota, and the virus also has been found in turkeys in Chile.
