Abstract:
OBJECTIVETo study the prevalence of SEN virus (SENV) infection in CHB patients in five cities of China.
METHODSA nest-polymerase chain reaction (nPCR) was used for detection of SENV-D and SENV-H in sera of 595 CHB patients from 5 cities of China and 96 normal individuals from Beijing. A total of 7 SENV strains were analyzed by direct sequencing.
RESULTSThe prevalence rates of SENV in CHB patients and normal individuals were 61.3% and 62.5%, respectively (chi(2) = 0.047, P = 0.829). The prevalence rates of CHB patients between 5 cities were different. Nucleotide sequence analysis showed that the homology between 4 SENV-D strains was 91% - 98% and 95% - 98% between 3 SENV-H strains isolated from 5 cities in China.
CONCLUSIONSENV-D/H were prevalent in CHB patients of China and their prevalence rates were similar to that in normal individuals.
