Interpretive Summary:

Technical Abstract: Distribution of genetic groups (genogroups) of Newcastle disease virus (NDV) isolated during 1986 to 2005 in the U.S. from 209 waterfowl and shorebirds (W&S) and 17 live bird market (LBM) samples was investigated. Waterfowl and shorebirds viruses were distinct from vaccine viruses and from the virulent genotypes that cause severe disease in poultry. Most genogroups were widely distributed across the US and present in multiple bird species with evidence of rapid genomic changes. The majority of Class I viruses found in US LBM in 2005-06 (15/17) belong to the same genogroup that infected mallard samples from the same region in 2004.
