Dynamic changes of INF-γ and IL-4 in the peripheral blood of mouse infected with Mycoplasma suis / 中国人兽共患病学报

ABSTRACT

The changes in the levels of IFN-γ and IL-4 in peripheral blood of mice infected with Mycoplasma suis were investigated in the present study, in which BALB/c mice were infected with Mycoplasma suis and the levels of IFN-γ and IL-4 in peripheral blood of mice were determined by means of ELISA assay 3, 5 and 7 days after infection. The results showed that the lower level of IFN-γ and higher level of IL-4 could be demonstrated 3 and 5 days after infection in comparison with those of the control groups respectively(P0.05) . It is evident from this result that determination of the levels of IFN-γ and IL-4 in peripheral blood of mice may constitute an additional sero-diagnostic index to infection with M.suis and provide the experimental data for the studies in the serology and immunology of this infection.
