| specificity of chicken secondary in vitro lymphoproliferative responses to a parakeet isolate of avian paramyxovirus-3. | partially inbred chickens of the birmingham b2 subline were primed with paramyxovirus-3/parakeet/netherlands/449/1975 (pmv 449), and secondary in vitro spleen cell responses were investigated with respect to virus specificity and histocompatibility restriction. pmv 449-primed spleen cells responded to stimulation with syngeneic lymphocytes infected with pmv 449 and other avian paramyxoviruses of the same serogroup, and showed a low level of cross-reaction with newcastle disease virus. yucaipa (p ... | 1988 | 18766707 |
| prevalence of antibodies to different avian paramyxoviruses in commercial poultry in the united states. | avian paramyxoviruses (apmvs) other than newcastle disease virus have been isolated from feral avian species and have the potential to cause clinical disease. the objective of this study was to investigate the apmv antibody prevalence in commercial poultry settings. sera from 100 commercial, layer-type and broiler-type (broiler-breeder and broiler) chicken flocks were analyzed on a random basis. pooled serum samples from each flock were tested for the presence of antibodies to apmv-1, -2, -3, -4 ... | 2008 | 19166066 |
| complete genome sequence of avian paramyxovirus-3 strain wisconsin: evidence for the existence of subgroups within the serotype. | the complete consensus genome sequence was determined for avian paramyxovirus (apmv) serotype 3 strain wisconsin. the genome is 16,182 nucleotides (nt) in length, consisting of six non-overlapping genes in the order of 3'-n-p/v/w-m-f-hn-l-5', with a 55-nt leader at its 3' end and a 681-nt trailer at its 5' end. comparison of the apmv-3 strain wisconsin nt and the aggregate predicted amino acid (aa) sequences with those of apmv-3 strain netherlands revealed 67% and 78%, identity, respectively. th ... | 2010 | 20079781 |
| isolation and characterization of avian paramyxovirus type 3b from farmed namibian ostriches (struthio camelus f. dom.). | meat and skin from farmed ostriches are valuable products for european consumers. the eu regulations require that ostrich products deamed for export need to come from ostriches that are free of antibodies against newcastle disease virus (avian paramxovirus type 1, apmv-1). after the detection of antibodies against apmv-1 in one of five ostrich farms in namibia, attempts were made to isolate the causative virus. no apmv-1 but an avian paramyxovirus type 3 (apmv-3) was isolated from five pharyngea ... | 2010 | 20329642 |
| status of wild birds in bulgarian zoos with regard to orthomyxovirus and paramyxovirus type 1 infections. | newcastle disease virus (ndv) and avian influenza virus (aiv) are pathogens of major economic and social importance, and the diseases they cause are often devastating, particularly in domestic poultry. both viruses are naturally found in a wide variety of wild birds, particularly aquatic species, where asymptomatic infection typically occurs. wild birds are therefore considered to be a natural reservoir for both viruses. wild birds kept in captivity are in an environment that promotes transmissi ... | 2010 | 20521660 |
| experimental avian paramyxovirus serotype-3 infection in chickens and turkeys. | avian paramyxoviruses (apmv) are divided into nine serotypes. newcastle disease virus (apmv-1) is the most extensively characterized, while relatively little information is available for the other apmv serotypes. in the present study, we examined the pathogenicity of two divergent strains of apmv-3, netherlands and wisconsin, in (i) 9-day-old embryonated chicken eggs, (ii) 1-day-old specific pathogen free (spf) chicks and turkeys, and (iii) 2-week-old spf chickens and turkeys. the mean death tim ... | 2010 | 20663473 |
| evaluation of the newcastle disease virus f and hn proteins in protective immunity using a recombinant avian paramyxovirus type-3 vector in chickens. | newcastle disease virus (ndv) belongs to serotype 1 of the avian paramyxoviruses (apmv-1) and causes severe disease in chickens. current live attenuated ndv vaccines are not fully satisfactory. an alternative is to use a viral vector vaccine that infects chicken but does not cause disease. apmv serotype 3 infects a wide variety of avian species but does not cause any apparent disease in chickens. in this study, we constructed a reverse genetics system for recovery of infectious apmv-3 strain net ... | 2011 | 21525340 |
| avian paramyxovirus serotypes 2-9 (apmv-2-9) vary in the ability to induce protective immunity in chickens against challenge with virulent newcastle disease virus (apmv-1). | the avian paramyxoviruses (apmvs) belong to the genus avulavirus of family paramyxoviridae. the apmvs are classified into nine serotypes on the basis of hemagglutination inhibition (hi) and neuraminidase inhibition (ni) assays, although some serologic cross-reaction exists. newcastle disease virus (ndv), which constitutes serotype 1 (apmv-1), is an important pathogen of poultry, but the pathogenic potential of the other apmv serotypes is poorly understood. although antibodies to apmv -2 to -9 ar ... | 2012 | 22222870 |
