Neospora caninum treatment induces tumor cell death. a Tumors harvested on day 21 after tumor inoculation from mice treated with PBS or N. caninum tachyzoites were stained with H&E. The top row shows the entire tumor area; the bottom row shows enlargement of a section of the tumor bed; bars = 500 μm and 50 μm. b Quantification of the percentage of cell death areas for each treatment group (mean ± SD; n = 5). Data were analyzed by the two-tailed Student t-test (b). *P < 0.05, **P < 0.01, ***P < 0.001
