Molecular Analysis of Human Metapneumovirus Detected in Patients with Lower Respiratory Tract Infection in Upper Egypt

Figure 3

Phylogenetic tree of partial F gene sequences of Egyptian HMPV. The tree was generated with Neighbor-Joining method with 1,000 bootstrap replicates and rooted to Avian metapneumovirus C (AMPV-C). Reference sequences representing the different HMPV genetic lineages were additionally included in the analysis. Egyptian viruses are shown in boldface. These viruses are identified by the geographic location, patient number, type of specimen, and year of isolation. The scale bar represents 2% of nucleotide changes between close relatives.
