Binding affinity of early oocysts to basal lamina components. Several basal lamina components were tested for oocyst binding, including laminin, collagen IV, or the combination of laminin, entactin, and collagen IV (Lam, Ent, Col IV). BSA was used as a negative control. The number of oocysts per field were counted and shown as fold change values compared to BSA. The average number is shown for three experiments on days 2 and 6 and for two experiments on day 3. Error bars represent standard deviation. Student’s T Tests were performed to compare each group to BSA, and * = p < 0.05, ** = p < 0.01
