Pirbright reveals new method to study poultry virus (IBV) which could reduce the need to use birds in research
An enzyme called trypsin boosts the growth of infectious bronchitis virus (IBV) strains in lab cell cultures, scientists at The Pirbright Institute have shown. This finding could enable researchers to study strains of the poultry virus that were previously inaccessible and potentially provide alternative vaccine production methods, which currently rely on eggs, therefore reducing the numbers of birds needed for research and vaccine production.
