influenza viruses and paramyxoviruses in ducks in the atlantic flyway, 1977-1983, including an h5n2 isolate related to the virulent chicken virus.from 1977 to 1983, waterfowl migrating along the atlantic flyway were annually monitored for orthomyxoviruses and paramyxoviruses in an area in central new york state. a total of 168 influenza isolates were obtained from 1,430 waterfowl. twenty-four combinations of hemagglutinin and neuraminidase subtypes were detected, with as many as 12 found in a single year. one combination, an h5n2 isolate in 1982, was closely related to the virulent chicken virus that appeared in pennsylvania in 1983. the ...19853833237
evaluation of newcastle disease virus immunoassays for waterfowl using a monoclonal antibody specific for the duck immunoglobulin light chain.in the present study a monoclonal antibody (mab 14a3) was tested for its reactivity against serum immunoglobulin y (igy) of several waterfowl species, and subsequently for its applicability as anti-species antibody in common immunoassays. western blot analyses demonstrated its broad cross-reactivity with the serum igy light chain of different duck species: muscovy duck (cairina moschata), mallard (anas platyrhynchos), white-winged wood duck (asarcornis scutulatus), common pintail (dafila acuta). ...200818568660
phylogenetic analysis of newcastle disease viruses isolated from waterfowl in the upper midwest region of the united states.this study was conducted to characterize newcastle disease virus (ndv) isolates obtained from waterfowl from the upper midwest region of the united states. a total of 43 ndvs were isolated by inoculation of cloacal samples in embryonated chicken eggs. these isolates were obtained from 24 mallards, seven american green-winged teals, six northern pintails, four blue-winged teals, and two wood ducks. partial sequences of fusion gene were analyzed to determine the pathotypes and genotypes involved.200919891788
wood ducks (aix sponsa) as potential reservoirs for avian influenza and avian paramyxoviruses.influenza a viruses (iavs) and avian paramyxoviruses (apmvs) are important pathogens of poultry worldwide, and both commonly occur in wild waterfowl, especially ducks in the family anatidae. although wood ducks (aix sponsa) are members of the anatidae, their behaviour differs from most other species in this family, which could affect the transmission of iavs and apmvs. we collected cloacal and oropharyngeal swab and blood samples from more than 700 wood ducks across nine states in the eastern un ...201525695149
