Abstract:
Objective To investigate the correlation between gut microbiota and hepatitis B virus(HBV) infection at different stage. Methods 84 patients aged 25 ~ 40 were enrolled in the study,the ALT,AST and HBV antigens and antibodies qualitatively detected. Then they were divided into four groups based on HBV related antigens and antibodies qualitative detection according to guideline for chronic HBV infection:48 in the protective antibody positive group where vaccine injection was performed for producing protective antibodies ,14 in the HBV recovery group 9 in chronic HBV infection group And 13 in antibody negative group where vaccine injection was done. Their fecal samples were collected and total DNA were extracted and subjected to enterobacterial repetitive intergenic consensus sequence polymerase chain reaction(ERIC-PCR). After ERIC-PCR,gel electrophoresis and genetool software were used to analyse the differences in the amount of bands and the position of main bands between groups. Results The amounts of bands in the antibody negative and chronic HBV infected groups were significantly smaller than the protective antibody group and HBV recovery group. The position of main band in the protective antibody group and HBV recovery group were wildly spread within groups ,and most main bands in the HBV recovery group were above 282 bp. The main bands in the antibody negative and chronic HBV infected groups were centralized in 60 ~ 70 bp. Conclusions Compared with the protective antibody group and HBV recovery group ,the richness of gut microbiota in the antibody negative and chronic HBV infected groups are significantly decreased and lack of microbiota above 200 bp in ERIC-PCR.
