Fig. 3From: Epidemiology and genotypic diversity of human metapneumovirus in paediatric patients with acute respiratory infection in Beijing, ChinaPhylogenetic relationships of the strains detected in HMPV-infected children. a NJ-tree constructed based on the partial N gene sequences (813 bp) of HMPV strains. b NJ-tree constructed based on the whole genome sequences of HMPV strains. The reference strain is marked with a ▲, and the strains analysed in this study are marked with ●. The country of origin for each reference and sample sequence is indicated by the following country codes: AR, Argentina; AU, Australia; CA, Canada; CN, China; JP, Japan; NL, Netherlands; PE, Peru; and US, United States of AmericaBack to article page
