Evaluation of the activation of peritoneal macrophages and production of intracellular nitric oxide in CD1 mice infected with T. gondii RH: (a) the percentage of activated macrophages in the peritoneal cavity is increased in treatments with lactobacilli, regardless of whether they are alive or dead, compared to the control group; (b) there is an increase in the production of nitric oxide in the group treated with immunobiotic compared to the other two groups. Data were combined from two individual experiments with three to five mice per group. Values represent the means ± SD. * p < 0.05; ** p < 0.01. PBS) phosphate buffered saline; IB) immunobiotic; PP) paraprobiotic; MFI) mean fluorescence intensity.
