ABSTRACT
AimTo explore the kinetic change of the IgG,T-cell subsets and IL-2 level from the mice infected with T. Spiralis. Methods The level of specific IgG A band IL-2 was determined by ELISA,the percentage of CD4+and CD8+ T-cells were examined by flow cytometry on 7, 14,21,28,35 days after mice infected with T. spiralis respectively. ResultAfter infected with T. spiralis,the level of IgG in mice rised gradually,and reached its peak on the 35th day. The change of T-cell subsets showed that CD4+T cells decreased,which CD8+Tcells increased. The ration of CD4+/CD8+cells decreased,and which was the obvious on the 14thday. It did not recover to normal level even on the 35th day. The IL-2 of level reached the peak on the 7th day after infected,then IL-2 level decreased quickly and lower than that of normal mice on 35th day after infected. Conclusion When the acute phase of T. spiralis infection,the immune function of host was inhibited. The protective immunity of against T. spiralis infection was cellular immunity mainly ,in cooperation with humoral immunity.
