Abstract

Samples of feces from 1,080 cattle in Chonnam area were examined for Buxtonella sulcata, Of these, 231 cattle (21.4%) were found to be infected with the ciliate. The incidence was higher in the dairy cattle than in the beef cattle. The cysts of the ciliate are almost spherical or sub-spherical and the mean length of $79.58{pm}11.76{mu}m$ corresponds quite closely with the mean width of $77.29{pm}11.41{mu}m$. The trophozoite is characterized by the position of the cytostome near the open cytopyge and by the curved groove running down from cytostome to the end of the body. Macronuclei of the cyst and trophozoite were only stained green by MFS solution.
