This means they have the potential to become a highly pathogenic avian influenza virus. Local American states have their restrictions for the importation of chickens or meats from the infected states. Taiwan also killed chickens infected with low pathogenic avian influenza virus. Thus, Taiwan should detect avian influenza virus in the imported chicken meats from other countries. Chicken meats will be sampled at the Keelong and Kaushiung harbors and the avian influenza genome in them will be tested with AIV NP primer. The samples showing positive to NP gene will be further tested with H5- and H7- specific primers. All the samples will be tested by virus isolation. AIV isolated will be tested their pathogenicity as soon as they are isolated. The purpose of this project is to prevent the invading of AIV from other countries. No other avian influenza virus will enter Taiwan over imported meat at the 95% confidence interval level.家禽流行性感冒進口禽肉病毒分離家avian influenzaimported poultry meatsvirus isolation
