Experimental Models of Ocular Toxoplasmosis
First described in Ctenodactylus gundi and simultaneously in rabbit, Toxoplasma gondii, an etiological agent of toxoplasmosis, affects different species of vertebrates and invertebrates, presenting different manifestations depending on the host. Ocular toxoplasmosis is one of the mean manifestations of toxoplasmosis in humans, affecting 2% of infected individuals in Europe and North America. Otherwise many aspects of ocular toxoplasmosis still await answer. One of the major factors limiting this process is the difficulty to obtain human samples, doing necessary the use of experimental models. By the way, animal models do not express reality of human disease. The present study defines a compilation of report cases and results that supports the choice of an ideal experimental animal model of ocular toxoplasmosis. Actual literature bears new researches contributing in the choice of a specific experimental animal model. Moreover, the choice must consider behavior, period of life, and maintenance in captivity and ocular toxoplasmosis manifestation. Previous studies contribute for a best-chosen experimental animal model, by the way fragmented information makes difficult to compare mostly animal models picked that do not present efficiency enough. In conclusion, experimental animal models are able to bring relevant information about the course of ocular toxoplasmosis.
