T. gondii can infect the gut mucosa by direct invasion of epithelial cells in the small intestine and these cells may respond directly to infection promoting a local immune response. C57BL/6 mice orally infected with a high parasitic load of T.gondii are highly susceptible, presenting a lethal ileitis. Recently, it was demonstrated that pretreatment with STAg protects C57BL/6 mice against intestinal pathology in oral T. gondii infection. To investigate the mechanisms induced by STAg in the small intestine in oral T.gondii infection, BALB/c and C57BL/6 mice were treated with STAg 48 hours before oral infection with 30 ME-49 cysts and sacrificed at 8 days of infection. Previous treatment with STAg were able of decrease parasitism and pathology in peripheral organs of BALB/c and C57BL/6 mice and induced a increase in amounts of goblet cells, IgA positive cells, Paneth cells and expression of cryptidin in the small intestine of both lineages of mice, moreover BALB/c mice presented higher amount of these cells comparing with C57BL/6 mice. The results suggests that STAg is able of promoting protective mechanisms in both lineages of mice, although these protection is more evidenced in BALB/c mice, and these mechanisms could be in part mediated by increase in goblet, Paneth and local secretion of IgA in the small intestine of mice orally infected with T.gondii.
