Comparison of Pathogenicity and Serologic Response of Four Commercial Infectious Bursal Disease Live Vaccines.
Various commercial vaccines for immunization of broiler chickens against infectious bursal disease (IBD) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. In this study the pathogenicity and serologic response of four IBD vaccines, cloned D78®, Bursine-2®, Bursimune® and Cevac Gambo-L®, were evaluated in specific pathogen f...
متن کاملProtective efficacy of commercial live vaccines against very virulent infectious Bursal disease virus (vvIBDV) in Ghana
