ABSTRACT

The gene, corresponding to the mature protein, of the major surface trophozoites antigen of Toxoplasma gondii (P30) was cloned in the pcDNA3 plasmid under the cytomegalovirus intermediate early promoter and used for the intramuscular immunization of Balb/c mice. The expression of the P30 antigen in the muscle of immunized animals was evaluated by indirect immunofluorescence. The expression of P30 antigen in the muscle of immunized animals was detected three days after immunization whereas in animals immunized with pcDNA3 plasmid and in non-immunized animals the results were negative.

Key words: Toxoplasma gondii , P30 antigen, DNA, immunization

RESUMEN

El gen del principal antígeno de superficie del trofozoito de Toxoplasma gondii (P30) fue clonado en el plásmido pcDNA3 bajo el promotor temprano de citomegalovirus y usado para la inmunización intramuscular de ratones Balb/c. La expresión del antígeno P30 en el músculo de los animales inmunizados fue evaluada tres días después por inmunofluorescencia indirecta. Se detectó la presencia del antígeno en los animales inmunizados, no así en los otros grupos.

Palabras claves: Toxoplasma gondii, antígeno P30, ADN, inmunización
