Human Viral Isolate Reference Sheet

 

 

Catalogue Item Name: hMPV-4

 

Isolate Published name: Peru1-2002

 

GenBank Accension number: DQ393715

 

Classification:  Human metapneumovirus (hMPV)  Strain: G gene, B2

 

Publication: This viral isolate was presented as Peru1-2002 in the phylogram published in Emerg Infect Dis 2006:12:347-350.

 

Passage: 1  Culture Host:  LLC-MK2 cells 

 

Time Period Host cells Infected:  7, 14, 20, and 22 days

 

Original Source Information: Specimen collected in South America in October 2002 from a 4 year-old patient with a flu-like illness. 

 

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.
