| characterization of field isolates of newcastle disease virus using antipeptide antibodies. | a recent australian field isolate of newcastle disease virus (ndv) was analyzed with antipeptide antibodies capable of differentiating between the sequences at the cleavage activation sites of fusion proteins of different ndv pathotypes. the isolate was found to have the same fusion protein cleavage activation signal as the v4 isolate of the queensland strain of ndv. however, the isolate failed to react with an antibody specific for the carboxyl-terminal extension on the hemagglutinin/neuraminid ... | 1994 | 8002877 |

| a cross-sectional survey of australian chicken farms to identify risk factors associated with seropositivity to newcastle-disease virus. | several outbreaks of virulent newcastle-disease occurred in australia in 1998-2000. we conducted a cross-sectional survey of 753 australian chicken farms to identify risk factors associated with the seroprevalence of chicken flocks with newcastle-disease virus (ndv). we had a 99.7% response rate to the survey and the overall prevalence of ndv seropositive farms was 39.8%. associations were analysed for the layer, chicken-meat and breeder production sectors in sector-specific logistic-regression ... | 2006 | 16950528 |
