Eimeria stiedai in rabbits: the presence of an oocyst residuum.
Observations on 5 different isolates of Eimeria stiedai from pure infections in laboratory-reared rabbits have confirmed the presence of an oocyst residuum. This structure was seen in 89--100% of the oocytes in cultures prepared both from the liver and from the faeces at different times during the patent period. The residuum consisted of 1--7 or more granules situated centrally in the oocyst and partially concealed by 4 sporocysts. The differential diagnosis of E. stiedai and E. coecicola is discussed.
