Avian Metapneumovirus Subgroup C Infection in Chickens, China
Figure 1. . . Genetic relatedness between the matrix (M) protein gene of members of avian metapneumoviruses (aMPV) and human metapneumovirus (hMPV). Phylogenetic tree was constructed on the basis of the neighbor-joining clustering method by using MEGA 5.10 software (www.megasoftware.net). Bootstrap values (based on 500 replicates) are indicated at each branching point. Reference strains obtained from GenBank are indicated. The M sequence of the isolate JC used in the phylogenetic analysis has been deposited in GenBank under accession no. JX422020. Scale bar indicates estimated phylogenetic divergence.
