DHAKA, Sept. 26 (Xinhua) -- Some 6,000 chickens were culled at Sahapur village in Sadar sub-district in Bangladesh's northwestern Bogra district, 170 km of capital Dhaka Tuesday night following the detection of avian influenza virus in a poultry farm.
The private news agency UNB on Wednesday reported that Nakul Saha, owner of the poultry farm, took several dead chickens for laboratory test on suspicion that they might have died of bird flu.
The laboratory test confirmed that the chickens died of avian influenza.
The avian influenza virus was first detected in a poultry farm in Savar, 25 km west of the Dhaka in March this year. Laboratory test results showed the existence of influenza virus of H5N1 variety. Tens of thousands of poultry birds were culled.
