Detection and Identification of(Protozoa: Apicomplexa) by Molecular and Ultrastructural Studies in Naturally Infected Korean Cattle () from Daejeon, Korea.

Abstract

To survey the prevalence ofinfections, 210 heart samples were collected from Korean native cattle () at an abattoir in Daejeon Metropolitan City, Republic of Korea. Sarcocysts were detected form 31 specimens (14.8%) and identified asvia transmission electron microscopy. The wall ofhas flattened protrusions that did not contain fibrils or microfilaments. The protrusions arose irregularly from the base, contained a fine granular substance, lacked internal microfilaments, and measured approximately 0.21-1.25 μm in length and 0.05-0.07 μm in width. Sequence analysis revealed 99.5% homology to. This is the first report on the prevalence ofin native cattle from the Republic of Korea.
