[Acute nonspecific inflammatory reaction and modification of resistance to Toxoplasma gondii].

Two series of mice have been injected by peritoneal route with a suspension of Toxoplasma diluted by logarithmic progression of ratio of ten. Only one of two series had been inoculated by pleural route with inflammatory inoculum (calcium pyrophosphate microcrystals). The mice with inflammatory-treatment developed a slightly higher resistance to toxoplasmosis infection: in this group, throughout the entire experiment, mortalities have been delayed, the evolution of LD 50 showed lower titer, death rates have been lower than in the untreated group.
