Objective@#To analyze the genetic characterization of glycoprotein M(gM.),glycoprotein L(gL) of varicella zoster virus.@*Methods@#According to the program of "Ministry of Science and Technology of China" , Based on the 12 suspected VZV patients monitored in Beijing (1 case), Shanghai (5 cases), Jilin (2 cases), Qinghai (1 case), Guangdong (2 case) and Sichuan (case) in 2007-2015. A total of 12 Vesicle fluid and throat swab samples were collected. Positive samples were identified by Agarose gel electrophoresis and two glycoproteingenes were amplified by polymerase chain reaction (PCR). Nucleotide sequences were determined and analyzed by PCR amplification of VZV positive specimens V-OKA-BK of the domestic varicella attenuated live vaccine and the Varilrix-1 of the imported attenuated live vaccine. Nucleotide sequences of VZV positive specimens, vaccinestrains (V-OKA-BK, varilrix-1) and GenBank foreign wild strains (41 strains), parentstrains (P-oka), vaccinestrains (V-oka, Varilrix, Varivax) were compared using BioEdit and MEGA 5.0.@*Results@#12 specimens were VZV positive. Compared with the vaccinestrains and the parentstrains, the GM gene of 1 positive specimen had radical mutation at 86686 sites, which resulted in amino acidmutation, 5 positive specimens had base mutation at 87844 sites, and 30 strains of foreign wild strains had the same variation at 87 844 sites. 1 positive specimens of gL gene in 101245 sites had base mutation, and led to amino acidmutation, 6 positive specimens at 101624, 101625, 101626 sites had base of loss and the foreign wild strains in these 3 sites had the same variation. Compared with the vaccinestrains, the nucleotide and amino acid homology of gM of 12 VZV positive specimens were 99.2%-100% and 98.2%-100%, respectively, and gL of those were 99.3%-100% and 98.6%-100%, respectively. Compared with 41 strains of foreign wild strains, homology of gM's nucleotides and amino acid were 99.3%-100% and 98.5%-100%, respectively; 99.1%-100% and 98.6%-100% for gL. The results of phylogenetic analysis showed that 7 VZV positive samples were on the same branch with 4 vaccinestrains and p-oka strain. Based on gL, 12 VZV positive samples were on the same branch as the vaccinestrains and p-oka strain.@*Conclusion@#This study demonstrates that the genes of gM, gL are highly conserved and remain stable immunogen, which may be involved in the attenuation of VZV and need to be further researched.
