OBJECTIVE: To learn the rabies genome molecular characteristics and compare the difference of China rabies lineages.
METHODS: The complete genomes of 12 strains from different China rabies lineages were amplified and sequenced, and all the China street strain genomes (total 43), Arctic and Arctic-like genomes were aligned using ClustalX2, the genome homologies were analyzed using MegAlign software, and the phylogenetic trees were constructed by MEGA 5.
RESULTS: First Arctic-like rabies genome in China (CQH1202D) was reported, and we supplemented the rabies genome data of China, ensuring at least one genome was available in each China lineage. The genome size of China V (11908nt) is obviously shorter than other lineages' (11923-11925nt) for the difference of N-P non-coding regions. Among different lineages, the genome homologies are almost under 90%. CQH1202D (China IV lineage) has close relationship with strains from South Korea and they share about 95% genome similarities.
CONCLUSION: The molecular characteristics of 6 different China rabies lineages were compared and analyzed from genome level, which benefits for continued comprehensive rabies surveillance, rabies prevention and control in China.
