Pathogenicity of Avian Paramyxovirus Serotype-3 in Chickens and Turkeys

چکیده
Members of the family Paramyxoviridae are pleomorphic enveloped viruses that contain a single-stranded, non-segmented RNA genome of 13-19 kilobases (Lamb and Parks, 2007). These viruses have been isolated from many species of avian, terrestrial and aquatic animals around the world. Some members of the family Paramyxoviridae are well known human (measles, mumps, respiratory syncytial virus and various human parainfluenza viruses) and animal (rinderpest virus, canine distemper virus and Newcastle disease virus [NDV]) pathogens, while the pathogenic potential of many others is still unknown. The family is divided into two subfamilies, Paramyxovirinae and Pneumovirinae. Subfamily Paramyxovirinae is further divided into five genera: Rubulavirus, Respirovirus, Henipavirus, Morbillivirus and Avulavirus. Subfamily Pneumovirinae is divided into two genera: Pneumovirus and Metapneumovirus (Mayo, 2002).

Isolation and pathogenicity identification of avian paramyxovirus serotype 1 (Newcastle disease) virus from a Japanese quail flock in Iran
Newcastle disease virus (NDV) was isolated and identified for the first time from a flock of Japanese quail suspected to ND in Iran. Birds of the flock aged variously, and some of them died from the disease. Loss of appetite, weakness and decrease in egg production, diarrhea and nervous symptoms were the main clinical signs in the birds. Hemorrhagic lesions of the intestinal tracts and proventr...
متن کاملExperimental 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 pa...

Characterization of isolated pigeon paramyxovirus-1 (PMV-1) and its pathogenicity in broiler chickens were studied. Two hundred and thirty-two samples collected from 50 unvaccinated pigeons lofts suspected to Newcastle disease from private houses and bird markets from Ahvaz, Iran. Swab samples from cloaca and oropharynx of live pigeons and from trachea, lung, liver, spleen, kidney, brain, prov...
