Abstract	Newcastle disease virus (NDV) strains are classified as having high (velogenic), intermediate (mesogenic), or low (lentogenic) pathogenesis and virulence in chickens. Recent studies have established that the hemagglutinin-neuraminidase (HN) protein plays an important role in viral tropism and virulence. A monoclonal antibody (AVS-I) has previously been shown to be specific for lentogenic strains of NDV (Srinivasappa et al., Avian Dis. 30:562-567, 1986) and is routinely used to identify these strains. We have used competition antibody binding assays with a previously characterized panel of monoclonal antibodies, binding to chimeric HN proteins, and the characterization of an escape mutant to localize the binding site of AVS-I to the extreme carboxy terminus of the protein. In addition, we have shown that AVS-I does recognize at least one mesogenic strain and one velogenic strain of the virus, calling into question the potential of this antibody as a diagnostic reagent for avirulent NDV strains.
