Morphology of 6 Eimeria species recovered from examined sheep. a Eimeria parva unsporulated oocyst. Note the lack of micropyle and polar cap. Inset: The sporulated oocyst has ovoid sporocyst, each sporozoite has central vacuole Scale bar = 25 µm. b Eimeria pallida unsporulated oocyst. Note the imperceptible micropyle (arrowhead). c Eimeria marsica unsporulated oocyst. Note the inconspicuous micropyle (arrowhead). d Eimeria crandallis unsporulated oocyst and sporulated oocyst. Inset: The sporulated oocyst has rounded or ovoid sporocyst and each has two vacuoles Scale bar = 25 µm. e Eimeria ovinoidalis unsporulated oocyst. Note the presence of micropyle without a polar cap (arrowhead). f Eimeria arloingi unsporulated oocyst. Note a distinct micropyle and the polar cap is lid-like and easily dislodged (arrowhead). Scale bar = 10 µm. Inset: The sporulated oocyst has elongated sporocysts and their sporozoite has large vacuole at the broad end. Scale bar = 25 µm
