Virulent Newcastle disease virus (NDV) is the worlds most lethal poultry virus. It attacks the digestive, nervous and respiratory systems and can cause up to 100% mortality in susceptible chicken. The disease can be controlled by vaccination which is usually administered individually, by intranasal, or intraocular routes, and the vaccine needs refrigeration.
This kind of vaccine made it impractical and difficult to administer to free range chickens. The requirement for a cold chain linking the manufacturer of the vaccine to the recipient chicken makes using the vaccine very expensive.
Researchers of the Faculty have been successful in selecting V4 strain of NDV for extreme heat resistance by sequential heat treatment and selection, and incubating the cultures up to 56oC. The researchers also found ways to supply the vaccine on some form of food, thus avoiding the need to catch chicken individually. This vaccine can also be administered by conventional routes.
The vaccine has been commercialised by Malaysian Vaccine and Pharmaceutical Sdn. Bhd. since 1993.
