Abstract
Infectious laryngotracheitis (ILT) is a significant viral disease of chickens in many countries around the globe. In this report the status of ILT in Australia has been used as a model to evaluate the evolution of the ILT viruses (ILTVs). Due to its geographical isolation, Australia harbored a distinct lineage of ILT viruses (ILTV) up to 2007. However examination of the ILT viruses (ILTV) involved in outbreaks between 2007 and 2009 has revealed that many of the outbreaks were caused by two new viral genotypes, class 8 and class 9. These two recombinant viruses were found to emerge as a result of recombination between previously existing live vaccine strains (SA2 and A20), and another live va..
