Abstract

Toxoplasma gondii is a parasitic protozoa present in warm – blood animal organisms. To complete its life cycle, the parasite must come into the cat´s body, because it can multiply only in the members of the cat family. In its lifetime the parasite meets various hosts, like intermediate and even blind hosts. To ensure the possibility of its reproduction while it is in the intermediate host, the parasite had to develop some abilities. The ability which T. gondii has, is the ability to manipulate with the host´s behaviour. The parasite influences mice´s behavior, in the way that the parasite decreases their innate fear of cats and in this way, a mouse becomes an easy prey, and the parasite manages to get into the cat. People are blind hosts for T. gondii. Parasite remains forever „ imprisoned“ in the human body because there is almost no possibility that the man. Recently, it has been also proved that it has an impact on changes of human behavior. T. gondii is a cause of various diseases of fetuses, and even their deaths. It has been proved that toxoplasmosis is associated with schizofrenia, because in the serum of many schizophrenics T. gondii antibodies were found, and many schizophrenics at some period of their life had contacts with domestic cats. The study of this parasite and its impact on humans, explained many mechanisms of diseases and the ways drugs act.
