Avian metapneumovirus (aMPV) emerged as an important respiratory pathogen causing acute respiratory tract infection in avian species. Here we used a chicken aMPV subgroup C (aMPV/C) isolate to inoculate experimentally BALB/c mice and found that the aMPV/C can efficiently replicate and persist in the lungs of mice for at least 21 days with a peak viral load at day 6 postinoculation. Lung patholo...
A simple and efficient collection method using hypotonic burst to isolate virions from infected cultured cells is described. Distilled water treatment of avian metapneumovirus (AMPV)-infected cells with thorough mixing and repeated pipeting was considerably faster for virion collection in avian cells compared to the widely used freeze-thaw (F-T) method (30 min vs. 3-4 h). This method was also m...
78 Abstract Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problem for human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamily Pneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ...
Human metapneumovirus (HMPV) is a pathogen associated with respiratory tract infection and is related to avian pneumovirus. Typically, children, the elderly, and those who are immunocompromised are the most susceptible to HMPV infection; however, the virus can infect persons of all ages. In otherwise healthy individuals, HMPV infection is generally self-limiting, but immunocompromised individua...
Avian metapneumovirus (aMPV) causes diseases like rhinotracheitis in turkeys, swollen head syndrome in chickens and avian rhinotracheitis in other birds. Causing respiratory problems, aMPV adversely affects production and inflicts immense economic losses and mortalities, especially in turkey flocks. In recent years, several serological and molecular studies have been conducted on this virus, es...
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...
