Abstract

The present study was arranged to include the use of four serological testes for diagnosis of toxoplasmosis in infected mice with treated or non treated tissue cysts and these tests included that latex agglutination test, modified latex agglutination test, IgM-ELISA and IgG-ELISA; the results showed the efficiency of modified latex agglutination test in the diagnosis of toxoplasmosis. On the other hand this study included that the effect of three chemical substances on the antibodies titers of infected mice with treated tissue cysts with these substances, the results showed that efficiency of saturated salt solution of NaCl, acetic acid and tartaric acid to increase antibodies titer in treated mice with these substances and then can be use these substances as food additive for decrease the infection reissue with toxoplasmosis by increase the efficiency of host immune response.
