Comparison between NJ tree of Thai rabies N genes and geographical distribution map. Neighbor-joining (NJ) tree based on 414 bp nucleotide sequences of the N genes of all 239 Thai rabies virus isolates compared with other 11 lyssavirus outgroups. Numbers along tree branches are >50% bootstrap supporting-value (1,000 replicates). The map of Thailand indicates geographical distributions of the 2 major phylogroups, TH1 and TH2, in a district-level (a subdivision of a province).
