Some 6,000 chickens have been culled at Sahapur village in Sadar sub-district in Bangladesh's northwestern Bogra district, 170 km of capital Dhaka, following the detection of avian influenza virus in a poultry farm.
The private news agency UNB Wednesday reported that the 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 H5N1 virus. Tens of thousands of poultry birds were culled at that time.
