Abstract
This study aimed to investigate the protective mucosal immunity elicited by live attenuated Vibrio anguillarum in fish. Zebrafish were immunized by bath or injection way, and undertook bath challenge at 28 days post vaccination. The results implied that bath vaccination was the better delivery route for inducing the protective immunity against bath challenge in zebrafish. The expressions of genes related to Th1, Th2 and Th17 cells were measured in the mucosal tissues of vaccinated and challenged zebrafish. Gene expression profiles showed that Th17-like responses were induced in mucosal immune system by vaccination via bath and injection routes while Th1 and Th2-like responses were not remarkable. Compared to injection vaccination, bath vaccination elicited the intense Th17-like immune responses in the gut tissue of zebrafish. Additionally, in gills and skin, Th17-like mucosal immunity elicited by injection vaccination occurred later than that by bath vaccination. Our results proved the immunological importance of gut in bath vaccination and the presence of two-compartmental model for immune response in zebrafish. In conclusion, bath vaccination more efficiently elicited protective Th17-like immunity than injection vaccination in mucosal tissues of vaccinated zebrafish. In turbot, effective immune protection against wild-type V. anguillarum was obtained by bath-vaccinated and the Th17-like responses were found in mucosal and systemic tissues.
