Donkey klossiellosis in Kenya.
Out of eight donkeys examined, two had gametogonic and sporogonic stages of Klossiella equi in their kidneys. Gametogonic stages included microgametocytes and macrogametocytes, some of them in syzygy. They were found in enlarged parasitophorous vacuoles situated in epithelial cells of the renal tubules. Sporonts were seen in the epithelial cells protruding into the tubular lumen while sporoblasts, sporocysts and sporozoites were found freely in the tubular lumen. Entire sporocysts were rarely encountered but sporozoites liberated from the ruptured sporocysts could be seen. No inflammatory reaction could be attributed to the presence of these parasites.
