Objective:To investigate changes in subsets of T cells in the spleen of mice by immunization with mix recombinant BCG-EmⅡ/3 and BCG-Em14-3-3 vaccine of Echinococcus multilocularis(Em)and against challenge with Em protoscoleces.Methods:BALB/C mice were subcutaneously and intranasally vaccinated with mix recombinant BCG vaccines respectively
then challenged with Em protoscolexes on 8w of vaccination and killed on 18w of infection to get spleen.Spleen cells were separated to measure subsets of CD4+ and CD8+T cells by FACsort
Blank vector
BCG and PBS served as control.Results:In the groups of immunization
CD4+subset increased significantly
as well as the ratio of CD4+/CD8+subset
but CD8+ subset had no change
CD4+ subset and ratio of CD4+/CD8+subset in the subcutaneous group were higher than these in the intranasal group.Conclusion:CD4+T cells subset may bear a part in protection induced in mice by mixed recombinant BCG-EmⅡ/3 and BCG-Em14-3-3 vaccine against challenge with Em protoscoleces.
