Creators Kitano Noritoshi

Liver flukes were found last year for the first time in the Misima-Usi (Misima Cattle) by the writer. The fecal examination was made July 17―25, 1954 at Misima Island. The examination was made according to the method of Watanabe, which is commonly used in Japan. Table 1 shows that positive cattle numbered 75 in a total of 233 head (i.e ., 31%). Table 2 shows the number of positive cattle with respect to age. Table 3 shows that the number of positive cattle with both liver flukes and Paramphistomum was 56 (i.e., 80%). The ova of liver flukes were not affected by the exterminative drug ltNeo hexaron” ( 0.1 g. per. kg.) as shown in Table 4.
