FIG 1.

Tissue burden of C. parvum organisms in the ileum and stool shedding of challenged mice, as altered by nutritional status. C57BL/6 mice, nourished or malnourished, were challenged with 2 × 10⁷ unexcysted oocysts per mouse and then euthanized 20 or 72 h later in order to determine the level of ileal tissue burden of organisms and parasite shedding. The number of parasites per milligram of tissue or stool was determined by quantitative PCR. Data are shown as the mean ± standard error of the mean (SEM) (n = 3 mice per group). *, P < 0.05 for malnourished infected versus nourished infected.
