Avian influenza
Avian influenza is a viral infection found in domestic poultry and a wide range of other birds. Wild waterfowl and shorebirds are often subclinically affected carriers of the virus. In poultry, low-pathogenicity strains can cause subclinical infections; however, some strains typically cause respiratory signs or decreased egg production. Highly pathogenic strains may cause widespread organ failure and sudden death, often with high mortality rates. Diagnosis is based on detection of the viral genome or specific antibodies or on virus isolation. Antimicrobials may help control secondary bacterial infection in flocks affected by low-pathogenicity strains. Antiviral drugs are not approved or recommended. Prevention is best accomplished by biosecurity measures. Vaccines matched for antigenic type can greatly increase resistance to infection, prevent clinical signs, and decrease viral shedding in infected flocks.
Siberia outbreak threatens south, Mediterranean.
Russia cordoned off roads and slaughtered hundreds of birds on Monday to contain the advance of a bird flu epidemic toward Western Europe.
The country's top state epidemiologist warned that the bird flu outbreak in Siberia also could spread through Russia's key agricultural areas in the south and then on to the Middle East and Mediterranean countries.
"An analysis of bird migration routes has shown that in autumn 2005...the H5N1 virus...

Agriculture Minister Cees Veerman has ordered farms to keep all poultry indoors during the bird migration season to minimise the risk of an outbreak of bird flu in the Netherlands.
Farms will have to keep their poultry in sheds until the end of the year and perhaps longer.
The regulation announced on Tuesday only relates to commercially-farmed birds and not to hobby poultry because the ministry believes the latter poses a "much smaller risk".
Veerman is to talk to representatives of...

Russian veterinary officials said Tuesday, Aug. 2, that an outbreak of an avian influenza strain that can infect humans has spread to another region in Siberia, while authorities were struggling to contain the virus.
The outbreak began in the Novosibirsk region in early July and has killed thousands of domestic fowl. The veterinary service last week identified the virus as the H5N1 strain, which can fatally infect humans, but no human cases have been reported in Russia.
The same strain...

An outbreak of bird flu has also been reported in neighbouring Kazakhstan.
Russian doctors suspect that migratory birds brought the virus to Siberia, where poultry is now in quarantine.
No human cases of the...
