^aInfection index: number of infected cells per 200 examined cells; ^bintracellular proliferation: number of parasites per 200 examined cells; ^cmedium alone. SP: scrambled synthetic peptide containing the same amino acids of KP in a different order. ^∗∗P < 0.01, ^∗∗∗P < 0.001, as determined by one-way ANOVA with Dunnett post hoc test vs. control.
