[Effect of the absence of vitamins in the diet on the excretion of giardia cysts: experimental study].

We have studied the effect of vitamin absence in the diet on the evolution of an experimental giardiasis in mice inoculated with Giardia muris cysts. Our study shows that although there is no decrease in the intestinal parasitation, the peak is delayed, and there is a significant decrease in the cysts elimination in stools. These features may have their clinical significance.
