The first cases of infection caused by avian metapneumoviruses (aMPVs) were described in turkeys with respiratory disease in South Africa during 1978. The causative agent was isolated and identified as a pneumovirus in 1986. aMPVs have been detected in domestic nonpoultry species in Europe, but tests for the detection of these viruses are not available in the United States. To begin to understa...
The contribution of cleavage activation of the fusion F protein of human metapneumovirus (HMPV) to replication and pathogenicity in rodents and nonhuman primates was investigated. Recombinant HMPVs were generated in which the naturally occurring trypsin-dependent cleavage sequence (R-Q-S-R downward arrow) was replaced by each of three sequences whose cleavage in vitro does not depend upon added...
Human metapneumovirus (HMPV) is a common virus that can cause respiratory problems ranging from mild upper respiratory tract disease to respiratory failure requiring mechanical support. Here, we report a case of a 32-month-old male with a previous history of asthma, who developed respiratory failure two weeks after onset of cough and rhinorrhea and required extracorporeal membrane oxygenation (...
