Infectious laryngotrachitis virus (ILTV) causes a highly contagious and acute infection in domestic and wild birds results in significant restrictions in the poultry industry, trade sanctions, and a severe economic slump. This requires increase in the public health level and use of control strategies such as vaccination. Reversion of virulence after reactivation of the latent virus and evident of possible outbreak are the major problems following vaccination. Peptide vaccines may improve control and produce long-term protection against ILTV.
