How do sporozoites of rabbit Eimeria species reach their target cells?

In all the studies performed on the invasion of the rabbit by sporozoites of 4 Eimeria species it was shown that the sporozoites first penetrate the duodenal epithelium; and then very quickly appear within the IELs of the duodenal epithelium. A few hours later they are found in IELs of their specific site of multiplication. The relationship between an "extraintestinal" route for sporozoites and the IELs homing phenomenon is therefore an exciting hypothesis.
