Source Information: Specimen collected in
Method of Identification Confirmation: Before evaluating the viral throat culture specimen for hMPV, it was found to be negative by routine viral culture for other common respiratory pathogens including: influenza A; influenza B; parainfluenza 1, 2, and 3; adenovirus; and RSV. The specimen was evaluated for hMPV by an RT-PCR procedure targeting the F gene (347bp amplicon) as published in JID 2003:187; 785-90. This testing resulted in a (3+) band and was reproducible upon repeat testing. The specimen was inoculated onto two LLC-MK2 shell vials. The cell culture media was aliquotted and frozen at -70° on days 7, 14, 20, and 23. No CPE was observed until three weeks. Supernatants were positive for hMPV by the above RT-PCR procedure. The 7-day supernatant gave a (2+) RT-PCR bands, the 14, 20, and 22 day supernatant gave (3+) bands. The sample was typed by sequencing PCR products of a partial region of the G gene and compared to our hMPV sequence library and NCBI.
