Abstract:
A molecular epidemiological analysis of newly isolated strains of EV71 in West Pacific Region was carried out. VP1 region of recently isolated EV71 were sequenced. Phylogenetic analysis had revealed 2 major genogroup B and C. Basing on nucleotid sequences in VP1 region, those 2 genogroups were divided into sub-groups of B1,B2,B3,B4 and C2,C2,C3,C4. North Vietnam isolated EV71 strains and 4 Shanghai isolate EV71 strains had composed a new genogroup belonging to C4 sub-group genes. South Vietnam isolated EV1 strains and Thailand recently isolated EV71 strains had composed special genogroup belonging C1 sub-group genes
