Extract

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 oocysts 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.
