Attenuated live infectious laryngotracheitis virus (ILTV) vaccines are widely used in the poultry industry to control outbreaks of disease. Natural recombination between commercial ILTV vaccines has resulted in virulent recombinant viruses that cause severe disease, and that have now emerged as the dominant field strains in important poultry producing(More)
Australian strains of infectious bronchitis virus (IBV) have been evolving independently for many years, with control achieved by vaccination with local attenuated strains. Previous studies have documented the emergence of recombinants over the last 20 years, with the most recent one, Ck/Aus/N1/08, detected in 2008. These recombinants did not appear to be(More)
Recent phylogenetic studies have identified different genotypic lineages of infectious laryngotracheitis virus (ILTV), and these lineages can recombine in the field. The emergence of virulent recombinant field strains of ILTV by natural recombination between commercial vaccines belonging to different genotypic lineages has been reported recently. Despite(More)
Infectious laryngotracheitis virus (ILTV) is an alphaherpesvirus that infects chickens, causing upper respiratory tract disease and significant losses to poultry industries worldwide. Glycoprotein G (gG) is a broad range viral chemokine-binding protein conserved amongst most alphaherpesviruses, including ILTV. A number of studies comparing immunological(More)
Although sequencing of the 3' end of the genome of Australian infectious bronchitis viruses (IBVs) has shown that their structural genes are distinct from those of IBVs found in other countries, their replicase genes have not been analysed. To examine this, the complete genomic sequences of the two subpopulations of the VicS vaccine, VicS-v and VicS-del,(More)
