Se estudió la capacidad como inmunógeno de la proteína SAG2 nativa del taquizoíto de T. gondii administrada por vía intranasal asociada con toxina colérica en ratones. El grupo de animales inmunizados con la proteína SAG2 sin adyuvante, presentó una menor carga de quistes cerebrales después del reto por vía oral con quistes de la cepa 76K de T. gondii. Se demostró la presencia de anticuerpos específicos contra esta proteína tanto en el nivel serológico (IgG), como en saliva (IgA), en todos los animales que recibieron la SAG2 en el esquema de inmunización.
The capacity of SAG2 native protein from the Toxoplasma gondii tachyzoite as an immunogen administered by intranasal route associated with cholera toxin in mice was studied. The group of animals immunized with SAG2 protein without adjuvant presented a smaller charge of cerebral cysts after the challenge by oral route with T. gondii 76K strain cysts. The presence of specific antibodies against this protein, both at the serological level (IgG) and in saliva (IgA), was proved in all the animals that received SAG2 in the immunisation scheme.
