Abstract: Recently a faecal sample from an 8-month-old calf from the Taranaki district was found to contain a large number of coccidial oocysts (960,000 oocysts per gram). After sporulation in a 2.5% potassium dichromate solution and concentration by sugar flotation, these were identified as being predominantly Eimeria zurnii. A small number of yellowish-brown oocysts distinguished by their thick radially-striated walls, obvious micropyle and absence of any oocyst or sporocyst residual body, were also present. These latter oocysts, which were of a pyriform shape and measured 38 μ long and 30 μ wide (mean of 10), were identified, according to the description of Joyner et al (1966) as being Eimeria bukidnonensis, a coccidian species previously unrecorded in New Zealand cattle. Eimeria bukidnonensis was first described by Tubangui (1931) from the faeces of a bull in the Philippines…
