Toxoplasma gondii is an important zoonotic parasite with a worldwide distribution. Felids are the definitive hosts and, upon primary infection, they shed millions of oocysts into the environment. These oocysts are infectious to a wide range of warm-blooded animals, and these intermediate hosts develop tissue cysts.

Toxoplasma gondii and mucosal immunity
International Journal for Parasitology, 2004Toxoplasma gondii, an intracellular parasite infects the host through the oral route. Infection induces a cascade of immunological events that involve both the components of the innate and adaptative immune responses. Alteration of the homeostatic balance of infected intestine results in an acute inflammatory ileitis in certain strains of inbred mice ...

Effect of Toxoplasma gondii on the Thymus
Nature, 1973IT has been shown1,2 that rabbits experimentally infected with a virulent strain of Toxoplasma develop a severe lymphocyto-paenia 3 d after infection and show marked changes in the thymus, chiefly by loss of cortical lymphocytes. In a study of congenital toxoplasmosis in mice, Beverley and Henry (ref. 3 and personal communication) observed depletion of

Immunology of Toxoplasma gondii
Immunological Reviews, 2011Summary: Toxoplasma gondii is an obligate intracellular parasite. Following oral infection the parasite crosses the intestinal epithelial barrier to disseminate throughout the body and establish latent infection in central nervous tissues. The clinical presentation ranges from asymptomatic to severe neurological disorders in immunocompromised ...

The Effect of Irradiation on Toxoplasma gondii
The Journal of Parasitology, 1963Complete loss of infectivity to mice was obtained when RH and Beverley strain Toxoplasma were exposed to radiation doses of 15,400 and 12,700 rads respectively. The dose necessary to achieve loss of infectivity of Beverley strain cysts in triturated brain was similar, approximately 14,900 rads. Some cysts in intact brain, however, remained viable at 22,

Toxoplasma Gondii and Homicide
Psychological Reports, 2012In a sample of 20 European nations, the prevalence of the brain parasite Toxoplasma gondii was positively associated with national homicide rates, amplifying previous research indicating a positive association of Toxoplasma gondii with suicide rates. Possible causal mechanisms were proposed.

Immunization against Toxoplasma gondii
Parasitology Today, 1994The emergence of Toxoplasma gondii as a major opportunistic organism in immunocompromised individuals and the steady increase in economic losses due to animal toxoplasmosis have fuelled the interest in vaccine development. In this review, Fausto Araujo addresses aspects of vaccination against T.
