Highly virulent bird flu virus detected in 2 swans

Friday 23rd May, 12:27 AM JST
AOMORI ?
The highly virulent H5N1 strain of avian influenza has been detected in two swans found dead or weakened at the shores of Lake Towada in Aomori Prefecture, the Aomori prefectural government said Thursday.
A similar strain has already been detected in dead swans found last month and earlier this month at the Towada lakeside in neighboring Akita Prefecture and the shores of Lake Saroma in eastern Hokkaido.

http://www.breitbart.com/article.php...show_article=1<TABLE cellSpacing=0 cellPadding=0 width="100&#37;" border=0><TBODY><TR><TD style="FONT-SIZE: 14px" vAlign=top width="99%">AOMORI, Japan, May 22 (AP) - (Kyodo)—The highly virulent H5N1 strain of avian influenza has been detected in two swans found dead or weakened at the shores of Lake Towada in Aomori Prefecture, the Aomori prefectural government said Thursday.
A similar strain has already been detected in dead swans found last month and earlier this month at the Towada lakeside in neighboring Akita Prefecture and the shores of Lake Saroma in eastern Hokkaido.
Genetic tests have showed that the H5N1 strain, detected in Akita Prefecture and Hokkaido, are very close to those detected in poultry in South Korea.
In Tokyo, the Environment Ministry said it will make a genetic analysis of the H5N1 strain detected in the swans in Aomori Prefecture in an effort to determine links, if any, among the viruses detected so far.
Among the two swans in Aomori Prefecture was one which was found weakened on April 18 at the premises of a hotel on Towada's southern lake side. It died two days later. The other was one found dead on May 8 in the northern part of Towada.
Both swans tested negative for avian influenza virus in a preliminary examination. But the deadly H5N1 strain was detected later in detailed checks by Tottori University conducted on request by the Environment Ministry, prefectural government officials said.
Separate from the two in Aomori Prefecture, another dead swan was found last Sunday in the village of Sai on the northern tip of the Shimokita Peninsula. It will be sent to Tottori University next week for detailed virus checks, the officials said.
Meanwhile, the Environment Ministry said it has conducted virus checks on some 100 wild birds captured at Lake Towada between May 5 and 8, and some 100 sets of droppings from wild birds at Lake Saroma on May 12. They tested negative for avian influenza virus.
Medical experts say H5N1, an avian disease, may mutate or reassort into a strain capable of efficient human-to-human transmission and that an outbreak of avian influenza could kill millions.
The Japanese government has continued efforts to build up stockpiles of a Swiss-developed anti-flu drug called Tamiful.

Whooper swan: 7 INFURU bird feathers weakness, rapid test is negative - three / Akita
County is 22, the town three days 12,15 debilitated whooper swan is a total of seven birds were found on Tuesday. A simple test bird flu virus were negative. The Ministry of the Environment received a request to send a sample of Tottori Univ.

Prefecture, said the three were found in the old town's three biggest towns Hatiryuu, Old Town, Yamamoto 4 feathers. Both rice paddy farmers in the town hall to find emaciated swans contact.

County is a simple test negative for bird flu virus. Area farms, and is not calling for attention. More than a week's time to announce the discovery of the Ministry of the Environment to report three or four days. The ministry will investigate all up to the prefecture of Tottori Univ asked to send.

Towada lake swans were found dead or debilitated after swans were found emaciated in a group is the first time. County is "vital test is a high accuracy. If you announce a deal in a positive, not to hide information," he said.

The Ministry of the Environment, Aomori Prefecture side of Lake Towada April 18 to May 8, weakened or dead (and satisfying) whooper swan found in two of the birds from the H5N1 strain of highly-virulent virus has been detected announced . One corpse is a simple test is negative. Naoko Baba []

H5N1 in Whooper Swans in Aomori Japan
Recombinomics Commentary 13:05
May 22, 2008

Aomori Prefecture. Towada lake Two of the swans were recovered from the H5N1 strain has been detected on Tuesday

Towadako Aomori Prefecture near the border of Akita Prefecture and the east coast of Oirase Gorge found in the estuary

The above translation describes the detection of H5N1 in two more whooper swans this week. They were in the same Towada Lake where the first positives were found a month ago (see satellite map). These swans were on the east side of the lake and therefore in the Amori Prefecture. A new outbreak in Korea was also reported this week, suggesting a new wave of birds may be migrating through the area.

The sequences of two isolates collected last month were virtually identical. There were Fujian (clade 2.3) reassortants with an HA related to clade 2.3.2. The other seven gene segments were related to clade 2.3.4. The NA sequence is most closely related to a human isolate from Guangdong province in 2006. The HA is closely related to a wild bird sequence from Hong Kong in 2007 which has been selected as the clade 2.3.2 vaccine target, but the sequence has been withheld. It is not clear of the withholding is linked to publication, or if the publication centers on the fact that the isolate is a reassortant. However, both isolates from Japan are reassortants, and the identity level of 99.7% or higher suggests the isolates in Korea are also Fujian reassortants linked to wild birds in Hong Kong..

Fujian sequences have not been reported previously in long range migratory birds like whooper swans. The detection in Japan over a one month period suggest that the level of Fujian infections is high, which is supported by the record levels reported in Korea, and the first reported H5N1 case in Primore in southeastern Russia.

The repeated detection of H5N1 in whooper swans in multiple locations over a one month time period raises additional concerns regarding an expanded geographical reach of H5N1. The current expansion in northeastern Asia involves the Fujian strain which has been more commonly reported in southern China and southeast Asia. Prior to the lab confirmation of H5 in the soldier in South Korea, the human Fujian isolates had been limited to the large clade 2.3.4 sub-clade. Since the 2007 / 2008 wild bird sequences in Hong Kong have not been released, it is not clear when the 2.3.2 / 2.3.4 reassortant formed, but its presence in long range migratory birds in locations in Japan and Russia in regions which have not previously reported H5N1 raise concerns of a significant global expansion of Fujian H5N1, which includes migration to North America.

More Suspect H5N1 Whooper Swans in Akita Japan
Recombinomics Commentary 15:10
May 23, 2008

debilitated whooper swan is a total of seven birds were found on Tuesday. A simple test bird flu virus were negative. The Ministry of the Environment received a request to send a sample of Tottori Univ.

Prefecture, said the three were found in the old town's three biggest towns Hatiryuu, Old Town, Yamamoto 4 feathers. Both rice paddy farmers in the town hall to find emaciated swans contact.

The above translation describes additional dead or dying whooper swans in the Akita prefecture. Although initial rapid tests are negative, both of the recent confirmed positives in Aomori initially tested negative with the rapid test, which lacks sensitivity.

If these birds test positive they will extend the geographic reach of Fujian H5N1 in northern Japan (see satellite map) and increase the likelihood that the long range migratory birds represent a global expansion of the Fujian strain (clade 2.3.2 / 2.3.4) of H5N1.

Last month H5N1 was confirmed at three distinct locations in northern Japan, and the most recent confirmed positives have extended that reach.

Japan has acknowledged the shortcomings of the rapid test and has sent samples for more sensitive testing. The H5N1 in whooper swans in Japan are closely related to the H5N1 in Korea, which has led to the culling of over 8 million birds.

Re: Japan detects bird flu in wild swans

Akita, Aomori and Hokkaido prefectures of Towada swan lake from the highly-virulent bird flu virus (H5N1) was detected in the issue, the ministry on May 29, 2005 is the virus to bird flu occurred in China The same virus strain belongs on Tuesday. On that day, held by experts virus infection routes of wild birds reported by the working group.

Akita and Hokkaido in the genes of the virus found in swans in the world, about 50 more than the H5N1 virus genes and compare, for 17 years in southern China and Vietnam, the problem was the same strain. Japan's virus is currently South Korea's poultry (KAKIN) epidemic viruses, are the same gene sequence is known, but the virus three years ago, the continents, South Korea and how did you I do not know each other in Japan.

Such as swans and ducks have already returned to the north, and do not host, the virus has been resolved by ultraviolet light and reduce any more, the potential spread of infection is low.

Re: Japan detects bird flu in wild swans

Towadako Akita Prefecture, whooper swan found dead from the virulent avian influenza virus has been detected problems, this virus has been found in Japan is different from the bird flu virus strain that分かりましHoops.

The problem is, last month and this month in Akita Prefecture and Hokkaido Towadako Notsuke Peninsula, including three whooper swan found dead from the virulent H5N1 strain of bird flu have been detected.

The virus, South Korea and the fury of one's heart and almost matches the bird flu virus that is known, but the virus found in Japan in the past, unlike three years ago, China and Vietnam and virus epidemic It is the same strain of the newly revealed.

The Ministry of the Environment, to strengthen surveillance of wild birds as well as to further investigate the route of infection. (29th, 21:41)

INFURU sporadically infected with bird experts are meeting in conclusion


Tohoku and Hokkaido dead swans from the highly-virulent H5N1 bird flu virus has been detected problems in the transmission route survey for the establishment of the Ministry of the Environment experts meeting on May 29, is infected with "locally, with sporadic What happened in the future spread is hard to believe that "he agreed.

Animal Health (Tsukuba, Ibaraki Prefecture) and other research, these viruses were detected in swans in the Korean viruses known to be almost identical, from the invasion of South Korea is suspected that the Concrete path is unknown.

The infected swans in the lake Towada, Aomori, Akita prefectures was found with multiple side, Notsuke Peninsula and Lake Saroma, Hokkaido, the one found in birds at a time. Because of the experts meeting, is limited to Towadako virus may have spread, Hokkaido, the wild swans to other regions in the middle of migration and likely力尽きたagreed .

Future measures for the implementation of the Environment Ministry's annual survey of wild birds to spread infection, decided to add a dead bird.
