Recovery of human metapneumovirus genetic lineages a and B from cloned cDNA.

ABSTRACT: Human metapneumovirus (hMPV) is a newly discovered pathogen associated with respiratory tract illness, primarily in young children, immunocompromised individuals, and the elderly. The genomic sequence of the prototype hMPV isolate NL/1/00 without the terminal leader and trailer sequences has been reported previously. Here we describe the leader and trailer sequences of two hMPV isolates, NL/1/00 and NL/1/99, representing the two main genetic lineages of hMPV. Minigenome constructs in which the green fluorescent protein or chloramphenicol acetyltransferase genes are flanked by the viral genomic ends derived from both hMPV lineages and transcribed using a T7 RNA polymerase promoter-terminator cassette were generated. Cotransfection of minigenome constructs with plasmids expressing the polyme
