Abstract A kinetics study and characterisation of target excreted/secreted antigens of immunoglobulin (Ig) G, M, A and E antibodies were realised by Western blotting with immune sera of mice inoculated with three strains ofToxoplasma gondii: RH, C56 and S3. IgG antibodies of the immune sera recognised the major proteins of the three excreted/secreted antigen preparations with molecular masses of 30, 45, 63 and 77 kDa. IgM antibodies recognised proteins revealed by IgG antibodies but with variable intensities; some proteins were revealed during a short period. IgA antibodies did not recognise the 35-kDa antigen or the antigens inferior to 28 kDa. The RH excreted/secreted antigens were revealed with the highest intensity. The IgE antibodies were briefly detected in trace amounts during period from the 20th to the 35th day. The RH strain with its excreted/secreted antigens had the best antigenicity and is a good model for immunoprotection studies.
