Prvalence and Morphological Identification of Eimeria bukidnonensis and E. wyomingensis in Cattle, Korea

국내(國內)소의 Eimeria bukidnonensis와 E. wyomingensis의 감염율조사(感染率調査)와 형태학적(形態學的) 특징(特徵)에 관한 연구(硏究)

To determine the prevalence and the morphological identification of two Eimeria species in fecal examinations, a total of 1092 fecal specimens collected during the period of March to December in 1987 was tested by means of flotation technique. The results obtained were summarized as follow: 1. The prevalence of two species was revealed as 1.83% and 0.92% in E. bukidnonensis and E. wyomingensis, respectively. 2. The oocysts of E. bukidnonensis measured in range of $41.3{\mu}m$ to $49.4{\mu}m(mean\;45.5{\pm}1.7){\times}28.8{\mu}m$ to $35.3{\mu}m(mean\;32.2{\pm}1.2)$, and E. wyomingensis $36.9{\mu}m$ to $44.5{\mu}m(mean\;39.8{\pm}1.7){\times}26.5{\mu}m$ to $29.9{\mu}m(mean\;28.2{\pm}0.9)$. 3. The oocysts of E. bukidnonensis appeared darker and more robust than those of E. wyomingensis. 4. The striations in the oocyst wall of E. bukidnonensis were more peculiar than in E. wyomingensis. 5. Among the morphological characteristic, the widths could be reliably taken as a differential point of view for two Eimeria species.
