Assessment of Preparation of Samples Under the Field Conditions and a Portable Real-Time RT-PCR Assay for the Rapid On-Site Detection of Newcastle Disease Virus.

Newcastle disease virus (NDV), also known as virulent forms of avian paramyxovirus serotype 1 (AMPV-1), is the causative agent of Newcastle disease affecting many species of birds and causing heavy losses to the poultry industry worldwide. Early, rapid and sensitive detection of the viruses or the viral nucleic acids is very important for disease diagnosis and control. This study aimed to evaluate sample preparation under field conditions and the application of a real-time RT-PCR method in the portable T-COR4 platform for the rapid, on-site detection of NDV on a farm.
