isolation of newcastle disease virus from teals (anas crecca) in iran.eight of 30 teals (anas crecca) died several days following capture and newcastle disease virus (ndv) was isolated from all eight. brains from the dead birds were homogenized and inoculated into chicken embryos. the allantoic fluid from the embryos were inoculated into 10 domestic chickens susceptible to ndv and 10 chickens immunized against ndv. eight of 10 (80%) susceptible chickens died, while the immunized chickens remained healthy. anti-ndv serum showed complete homology against ndv and the ...1979480525
avian influenza viruses and paramyxoviruses in wintering and resident ducks in texas.cloacal swabs were collected from teal (anas crecca, anas cyanoptera, anas discors), mottled duck (anas fulvigula) and northern pintail (anas acuta) in brazoria county, texas, usa, during february 2001, mottled ducks during august 2001, and blue-winged teal (a. discors) during february 2002. prevalence of avian influenza virus (aiv) infections during each sampling period were 11, 0, and 15%, respectively. the hemagglutinin (h) subtypes h2 and h7 were detected in both years, while the h8 subtype ...200516244076
[monitoring influenza a virus and newcastle disease virus in migratory waterfowls in sanjiang natural reserve of heilongjiang province].in order to monitor the present situation of avian influenza virus (aiv) and newcastle disease virus (ndv) in migratory waterfowls effectively, 158 tracheal and cloacal swab samples for wild birds were collected from sanjiang natural reserve during migratory seasons in october 2005, april 2006 and october 2006.200819160826
complete genome sequence of a newcastle disease virus strain belonging to a recently identified genotype.we report the first complete genome sequence of a strain that presents some pathogenicity and that belongs to a recently characterized genotype of avian paramyxovirus type 1 (apmv-1). this virus, isolated from the common teal, presents the most divergent genome within class i of apmv-1.201323405340
