Estimating the term…
The present invention provides a recombinant, attenuated infectious laryngotracheitis virus comprising the infectious laryngotracheitis viral genome which contains a deletion in the glycoprotein gG gene. This attenuated virus is useful as a vaccine against infectious laryngotracheitis virus. The present invention also provides a recombinant, attenuated infectious laryngotracheitis virus comprising the infectious laryngotracheitis viral genome which contains a deletion in the US2 gene, UL47-like gene, ORF4 gene or glycoprotein g60 gene. The present invention also provides a method for distinguishing chickens or other poultry vaccinated with a recombinant infectious laryngotracheitis virus which produces no glycoprotein gG from those infected with a naturally-occurring infectious laryngotracheitis virus.
A recombinant infectious laryngotracheitis virus comprising an infectious laryngotracheitis viral genome which contains a deletion in the unique short region of the infectious laryngotracheitis viral genome, wherein the deletion is in the glycoprotein G (gG) gene.
