Miyazaki avian flu almost identical to one in China
The avian flu that killed thousands of chickens in
Miyazaki Prefecture is almost identical to the one that sparked the epidemic in
The same H5N1
strain is believed to have caused an epidemic in South Korea in November last
year. The National
Institute of Animal Health in Tsukuba
, Ibaraki Prefecture, has been
analyzing the virus after obtaining samples from dead chickens at a poultry farm
in Kiyotake, Miyazaki Prefecture
, in mid-January. The experts, citing test
results of DNA samples, said the highly virulent strain of the virus might have
been carried by migratory birds from China to Japan.
The test results showed that the strain found on the Kiyotake farm was at
least a 99% match in terms of DNA sequencing with the H5N1 strain confirmed in
in May 2005. Scientists were shocked by the birds' deaths because they had
shared the view that wild fowl, in general, would not develop symptoms stemming
from avian flu.
