Genetic and antigenic variation of shedding viruses from vaccinated chickens after challenge with virulent Newcastle disease virus.

Avian diseases - 1 Jun 2013

Abstract excerpt

Newcastle disease virus (NDV) isolation was attempted from La Sota-vaccinated or unvaccinated chickens exposed to the virulent NDV variant E347Kmt. Shedding viruses were purified by plaque assay and then were sequenced for HN and F genes. The amino acid sequences of the F gene of all shedding viruses were identical to the sequence of the challenge virus. However, amino acid substitution occurred at four positions...
