Scientists have developed a potential vaccine against Newcastle disease


Researchers develop potential vaccine against Newcastle disease

Scientists have developed a new vaccination that could help farmers eradicate Newcastle disease from their flocks.

Researchers at Auburn University, Alabama developed a vaccine that has shown to protect birds from both Newcastle disease and infectious laryngotrachetis (ILT).

While vaccines for ILT already exist, treatments currently available are not entirely successful in preventing periodic outbreaks, and can even cause permanent latent infections in flocks.

Funded by USPOULTRY and the USPOULTRY Foundation, scientists wanted to develop a new treatment using gene technology that was more effective and safe to use.

Jospeh Giambrone, the project’s principal investigator, said the new vaccine was created by inserting a gene from the ILT virus into the B1 Newcastle disease virus — one of the most commonly used vaccines for controlling Newcastle disease.

The process results in a vaccine that encourages an immune response against both diseases, Giambrone added.

Scientists are now evaluating the safety of the vaccine and its ability to protect against the two viruses when it is safe to use at the hatchery in day-old broiler chicks.

Giambrone said he hopes the vaccine will become an important tool in maintaining bird health without establishing a permanent infection in broiler flocks.
