The Relative Levels of Neutralizing and Precipitating Antibodies Against Infectious Bursal Disease Virus and Their Correlation with Resistance to a Highly Virulent Challenge Strain

The Relative Levels of Neutralizing and Precipitating Antibodies Against Infectious Bursal Disease Virus and Their Correlation with Resistance to a Highly Virulent Challenge Strain

Maternai antibodies, even at relatively high levels protecting against mortality and gross bursal les ions, appeared to be inadequate in preventing infection with a highly virulent infectious bursal disease virus (IBDV) strain. A comparison between the sensitivity of a cell culture microtitre virus neutra/ization (VN) technique and a quantitative agar gel precipitation (QAGP) test, used to meas...

Protection against infectious bursal disease virulent challenge conferred by a recombinant avian adeno-associated virus vaccine.

The development and use of recombinant vaccine vectors for the expression of poultry pathogens proteins is an active research field. The adeno-associated virus (AAV) is a replication-defective virus member of the family Parvoviridae that has been successfully used for gene delivery in humans and other species. In this experiment, an avian adeno-associated virus (AAAV) expressing the infectious ...
