متن کاملProtective efficacy of commercial live vaccines against very virulent infectious Bursal disease virus (vvIBDV) in Ghana
In spite of the intensive and varied vaccination procedures to control Infectious Bursa Disease (IBD), the emergence of a very virulent (vv) IBD pathotype in Ghana has led to high economic losses in the poultry industry. The potencies of two live intermediate IBD vaccine strains (TAD and Nobilis D78) and an intermediate-plus (hot) vaccine strain (228E) used in Ghana were evaluated by challengin...
