| Abstract: | The MET95 strain of a lentogenic Newcastle disease virus (NDV) isolated from a broiler in Japan, showed unique hemagglutination (HA) activity. The MET95 strain failed to show HA when examined by rapid glass plate method although they showed HA titer of 1:1,024 by micro-plate method. This unique HA was also observed after the MET95 strain was passaged ten times in chickens. The failure of HA by rapid glass plate method was not shown in any other NDVs examined. |
