RESUMO

To describe epidemiologic characteristics of norovirus infection and its genotype in Shenzhen area of 2010. Stool specimens were collected from four monitoring point and detected by reverse transcription polymerase chain reaction (PT-PCR). Positive PCR products were purified and sequenced, and the sequences were performed by Clustal W and MEGA 4.0 programs, then genotype was identified and phylogenetic tree was constructed. Nucleotide sequence analysis revealed that 79 strains of NV belonged to norovirus genogroup II and 6 belonged to genogroup 1 of all 85 positive products. While 55 strains belonged to G II/4(2006b), 16 strains belonged to G II/4(2008 variant), 2 strains belonged to G II /1, 4 strains belonged to G II/5, 2 strains belonged to G II/11, 1 strain belonged to GII/4, 2 strains belonged to GII/5, 3 strains belonged to GI/6. The main genogroups of norovirus in Shenzhen ware GI and G II. G II /4 was one of the most major genotype of norovirus , while G II /4(2006b) variant was identified as the predominant strain in Shenzhen area.
