ILT is an acute, highly contagious herpesvirus infection characterized by severe breathing difficulties and coughing in poultry. It spreads rapidly from bird to bird causing high mortality rates and damaging flock health and performance.
ILT is a viral infection of the respiratory tract of chickens and is found in all parts of the world where poultry are intensively raised. It is mainly spread through the respiratory tract and conjunctiva and symptoms include coughing and gasping. Causing a drop in egg production and increased morbidity rates, ILT is a major threat to poultry producers.
As there are no current treatments for ILT, preventing an outbreak of the disease is essential. Layer flocks can be vaccinated with one or two doses of modified live virus vaccine, but these may cause post-vaccination reactions. Herpesvirus of turkey (HVT) based vaccines can be applied in ovo or in the hatchery for long-term protection that is also reaction-free as HVT removes the need for a live virus and is safe to chickens.
A single-shot vaccine that provides long-term protection against both Infectious Laryngotracheitis and virulent Marek’s Disease, Innovax-ILT removes the need for transmissible live vaccines.
