DONKEY KLOSSIELLOSIS IN KENYA

Out of eight donkeys examined, two had gametogonic and sporogonic stag es of Klossiella equi in their kidneys. Gametogonic stages included mi crogametocytes and macrogametocytes, some of them in syzygy. They were found in enlarged parasitophorous vacuoles situated in epithelial cel ls of the renal tubules. Sporonts were seen in the epithelial cells pr otruding into the tubular lumen while sporoblasts, sporocysts and spor ozoites were found freely in the tubular lumen. Entire sporocysts were rarely encountered but sporozoites liberated from the ruptured sporoc ysts could be seen. No inflammatory reaction could be attributed to th e presence of these parasites.
