Analysis of the genetic sequences of the H5N1 viruses detected in Germany and Czechoslovakia this past week indicate both are genetically similar, and likely derived from a common source.

BERLIN, June 28 (Reuters) - The deadly strains of bird flu that has killed birds in the Czech Republic and southern Germany are similar and most likely have a common origin, Germany's top state veterinary laboratory said on Thursday.
The Czech Republic reported finding the deadly H5N1 strain of avian influenza virus at two poultry farms and in a dead swan. Germany has found the virus in a number of wild birds in the eastern state of Saxony and southern state of Bavaria.
Germany's Friedrich Loeffler Institute said it compared the viruses found in a wild swan near the Bavarian city of Nuremberg with samples from a Czech turkey farm and found that they had a 99.2 percent match.
"The degree of similarity points to an as yet undetermined common origin for both viruses," the institute said in statement.
The institute said it was not clear if there was a direct connection bewteen the outbreaks in Bavaria and Czech Republic but said they appeared to be the highly pathogenic Asian strain of H5N1 circulating in the Middle East.
Last year, some 13 European Union member states had confirmed cases of bird flu -- Germany, Austria, Denmark, Italy, Greece, Britain, the Czech Republic, Poland, Slovakia, Slovenia, Sweden, France and Hungary.
