Effects of dissolved oxygen and pH on the expression of a type HBGA-like in pacific oyster

Objective: To study the effects of dissolved oxygen and pH on the expression of A type HBGA-like in pacific oysters. Methods: The HBGAs-like in the pacific oysters were isolated and extracted, and the human HBGAs were used for typing. The A type HBGAs was detected by ELISA method, and the P/N value was calculated. The content changes of A type HBGA-like in the guts and gills of pacific oysters were detected by changing the dissolved oxygen content and pH of seawater under artificial simulation conditions. Results: The HBGA-like of different tissues of oysters were classified, and the A type HBGA-like of gut and gill were selected as the main research type of subsequent experiments; the artificial simulation experiment results showed that the high pH could improve the expression of A type HBGA-like in pacific oysters gills, and the high dissolved oxygen can also improve the expression of A-type HBGA-like in pacific oysters guts. Conclusion: The results were consistent with the phenomenon that the norovirus outbreak usually occur in winter and spring, indicating that the seasonality of norovirus outbreak was correlated with the expression of A type HBGAs-like in oyster.
