The fresh outbreak of avian influenza took place in the Rostov Region, in the village of Shosseiny, some 10 km (6 miles) from the poultry farm where the first case of bird flu was registered in the region in late November.

"37 dead poultry were found, following which the entire population of 50 birds was culled," the officials said.

Birds started dying at the Gulyai-Borisovskaya poultry farm in the Rostov Region on November 29, and an analysis showed traces of the lethal H5N1 strain. The farm's entire population of 500,000 chickens has since been culled. A bird flu outbreak was later registered at private subsidiary holdings located close to the farm.

A second bird flu outbreak in the Rostov Region was later registered at a private farm in the Tselinsky district.

The outbreak in the Rostov Region is the third this year in Russia. The Krasnodar Territory, which is on the route taken by migrating birds in winter, was hit by the H5N1 strain in September, and a total of 230,000 birds were culled.

In February, dead poultry with traces of the lethal virus were found in Moscow, eight districts of the Moscow Region and a district in the Kaluga Region. All cases were traced to a single market in southwest Moscow.

The virus, which was first isolated in humans in 1997, has been spreading rapidly, resulting in the deaths and culling of millions of birds, and a human death toll of over 200.

Although the virus has so far been mainly restricted to animals, many scientists fear that it could mutate into a form transmissible between humans, unleashing a catastrophic global pandemic similar to the Spanish flu outbreak of 1918 that killed millions around the world.

ROSTOV-ON-DON, December 20 (Itar-Tass) - A third outbreak of bird flu has been registered in the Rostov region, the regional emergencies department said on Thursday.
According to laboratory tests, several dozens of birds died from the virus in a private backyard in the village of Shosseiny, Zernograd district.
All birds in the backyard were culled. Quarantine checkpoints were created in the village.
The bird flu virus was registered in two villages of the Rostov region. Around 500,000 birds were culled at a poultry farm of the village of Gulyai Borisova. In the village of Sladkaya Balka all poultry was culled and burnt at a private backyard, where two dead birds had been found. The quarantine was imposed in Sladkaya Balka, too.
Experts say the source of the virus is migration birds.

H5N1 Spreads in Rostov

Recombinomics Commentary
December 20, 2007

The third outbreak of bird flu has occurred in Russia's Rostov region, the regional department of the Emergency Situations Ministry told Interfax.

"Thirty-seven chickens and geese have died at a private farm in the village of Shosseiny. The farm had 50 birds, the remaining birds were destroyed," the department said.

Another bird flu outbreak occurred at a private farm in the village of Sladkaya Balka in the Rostov region.

The above comments describe two more H5N1 outbreaks in Rostov. These are in addition to the earlier outbreak at a large commercial facility at the end of last month, and the adjacent Krasnodar outbreak in September (see satellite map).

The sequence of H5N1 from a chicken in Krasnodar was the Uva Lake strain and was closely related to sequences from wild bird isolates from three locations in Germany. Recently, H5N1 was sequenced from a whooper swan in Krasnodar, and the HA sequence was an exact match with the chicken sequences. Full sequences were generated for all eight gene segments for both Krasnodar isolates. The sequences were 99.95% identical demonstrating that the poultry outbreak was due to another introduction of H5N1 into the region via wild birds.

In addition to these public sequences, descriptions of sequences from outbreaks in Kuwait, Czech Republic, France, England, and Germany are related to the Uva Lake strain, suggesting that recent outbreaks in Poland, Romania, Rostov, Saudi Arabia, and Pakistan will also be related to the sub-clade that traces back to the massive wild bird outbreak at Uva Lake.

Although H5N1 in the Black Sea region in the fall has been reported in 2005 and 2006, reports of H5N1 in western Europe and the Middle East was not. The reports of H5N1 in Europe in the summer signaled an endemic H5N1 in wild birds, which would lead to more frequent detection in the fall, which has happened this year. The human cases in Pakistan raises concerns that the additional cases expected in the upcoming weeks will lead to human cases in countries which have never reported human H5N1 infections previously.

ROSTOV-ON-DON, December 25 (RIA Novosti) - A fifth case of bird flu has been confirmed at a farm in the Rostov Region, south Russia, close to the site of previous outbreaks, the regional emergencies ministry said. "The outbreak at two smallholdings was registered on Saturday, samples were taken and sent for analysis, they came back positive for bird flu," the ministry said.
All 79 birds on the smallholding have been culled. A quarantine zone has been introduced in the Tselinsky district near the site of the first case of the deadly virus.
The first bird flu outbreak was discovered in late November at the Gulyai-Borisovskaya poultry farm in the Rostov Region. The farm's entire population of 500,000 chickens was culled. Later a bird flu outbreak was registered at a smallholding close to the farm.
Another outbreak was then discovered at a farm in the Tselinsky district.
The Rostov Region is particularly vulnerable to bird flu as part of the Krasnodar Territory, which is on a route taken by migrating birds in winter. In September, the region was hit by the H5N1 strain and 230,000 birds were culled.
In February, dead poultry with traces of the lethal virus were found in Moscow, eight nearby areas. All cases were traced to a single market in southwest Moscow.
The virus, which was first isolated in humans in 1997, has been spreading rapidly, resulting in the deaths and culling of millions of birds, and a human death toll of over 200.

More than half a million birds culled on southern Russian farm after bird flu outbreak



ROSTOV-ON-DON, Russia: Authorities have culled more than half a million domestic birds on a farm in southern Russia hit by the H5N1 strain of bird flu, officials said Tuesday.
More than 600,000 chickens on the Gulyai-Borisovskaya farm in the Rostov-on-Don region have been destroyed to prevent the virus from spreading, said Oleg Ugnivenko, a spokesman for the regional branch of Russia's Emergency Situations Ministry.
The virus also sickened birds in the neighboring Tselinsky district, and authorities have taken steps to stop it from spreading, Ugnivenko said.
In September, authorities reported an H5N1 outbreak at a poultry farm in the neighboring Krasnodar region, and early in the year the strain was confirmed in several other regions across Russia.
No human cases of bird flu have been reported in Russia, which had its first reported cases of H5N1 in Siberia in 2005. World health authorities are tracking the H5N1 strain out of concern that it could mutate into a form more easily transmitted among people, sparking a global flu pandemic.

In one additional settlement of Rostovskaya province the bird influenza is discovered

In the Rostovskaya province is revealed the fifth focus of bird influenza - in the settlement northern Of the tselinskeyeo region. Previously virus was revealed in two regions of Rostovskaya province - Zernogradskom and Tselinskom: at the Go for a walk- Borisov poultry processing facility, in the farmsteads go for a walk -Borisovka, sweet beam, settlement highway.
As they reported to correspondent IA regnum in the administration of the veterinary science of Rostovskaya province, yesterday, on 24 December, were obtained the results of the analyses of the fallen bird, carry ouied by provincial veterinary laboratory. They confirmed the presence of the genome of the virus of bird influenza in the investigated models.

Is earlier by two podvor'yakh of settlement north bollard seven head of poultry. Yesterday the decision of the chapter Of the tselinskeyeo region to the farmstead superimposed quarantine. Quarantine measures are conducted. Entire poultry on these podvor'yakh - 79 heads - is already utilized. The fulfillment of all quarantine measures assumes the destruction of entire livestock of poultry in the zone of quarantine - in the settlement northern. This approximately of 5 455 head of bird.

Furthermore, according to the order of the chapter of region, on the entrances from the populated area quarantine barriers are advanced, organized duty of two it is point-duty the police, are reploughed all secondary roads. In all since the beginning of the detection of the virus of bird influenza are utilized about 517 thousand head of bird, including in the past twenty-four hours are destroyed 1 287 heads.
According to the information of provincial control of veterinary science, by the source of bird influenza in the Rostovskaya province of steel the wild filantropnye birds: sparrows, rooks.

Re: Russia: Poultry H5N1 Confirmed

http://www.ncbi.nlm.nih.gov/pubmed/18756811
The paper presents the results of interpreting the epizootic outbreak etiologically
associated with high-virulent influenza virus A/H5N1 among domestic and wild birds
in the Zernogradsky and Tselinsky districts of the Rostov Region.
Epizooty was characterized by a high infection rate in the synanthropic birds of a
ground-based complex. RT-PCT revealed influenza virus A/H5 in 60% of pigeons
and crows and in around 20% of starlings, and in 10% of tree sparrows.
Fifteen viral strains from chickens (Gallus gallus domesticus), Indian ducks
(Cairina moschata), rooks (Corvus frugilegus), rock pigeons (Columba livia),
tree sparrows (Passer montanus), common starlings (Sturnus vulgaris),
and great white herons (Egretta alba) were isolated and deposited in the
State Collection of Viruses of the Russian Federation.
Full-sized genomes of 5 strains were sequenced and deposited in the
international database GenBank. The isolated strains belong to the
Quinhai-Siberian (2.2) genotype, an Iranian-Northern Caucasian subgroup,
they are phylogenetically closest to the strain A/chicken/Moscow/2/2007
(inducing epizooty among poultry in the near-Moscow Region in February 2007)
and have 13 unique amino acid replacements as the consensus of the Quinhai-Siberian
genotypes in the proteins PB2, PA, HA, NP, NA, and M2, by preserving thereby
4 unique replacements first describes for the strain A/chicken/Moscow/2/2007.
The findings are indicative of a different mechanism that is responsible for bringing
the virus into the northeastern part of the Azov Sea area in September 2007
(during the fall migration of wild birds) and in December 2007 in the south-western
Rostov Region where a human factor cannot be excluded. Mass infection of
synanthropic birds endangers the further spread of epizooty, including that in
the central regions of the Russian Federation in spring after near migrants
return after wintering.
