Prevalence of avian metapneumovirus subtype B in live bird market in Gilan province, Iran
Avianmetapneumovirus (aMPV), also known as avian pneumovirus or turkey rhinotracheitis virus, is the causative agent of turkey rhinotracheitis and swollen head syndrome in chickens. Four aMPV subgroups (A-D) have been reported previously based on their genetic and antigenic differences. Evidence suggests that the live bird markets (LBMs) play an important role in the epidemiology of the avian v...
متن کاملAvian Metapneumovirus Subgroup C Infection in Chickens, China
Avian metapneumovirus causes acute respiratory tract infection and reductions in egg production in various avian species. We isolated and characterized an increasingly prevalent avian metapneumovirus subgroup C strain from meat-type commercial chickens with severe respiratory signs in China. Culling of infected flocks could lead to economic consequences.
متن کاملExperimental infections of broilers with avian Metapneumovirus subtype A and B
Avian Metapneumovirus (aMPV) affects both turkeys and chickens. The virus is associated with swollen head syndrome (SHS) in broilers. Most of the studies regarding aMPV have been done in turkeys. Not much is known about the pathogenesis and immune response to aMPV in broilers. Therefore, our objectives were to study the pathogenesis and immune responses of broilers experimentally infected with ...
متن کاملIsolation and characterization of avian metapneumovirus from chickens in Korea
Avian metapneumovirus (aMPV) causes upper respiratory tract infections in chickens and turkeys. Although the swollen head syndrome (SHS) associated with aMPV in chickens has been reported in Korea since 1992, this is the study isolating aMPV from chickens in this country. We examined 780 oropharyngeal swab or nasal turbinate samples collected from 130 chicken flocks to investigate the prevalenc...
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...
