A total of 87 brains from harvested and collected wapiti and red deer (Cervus spp.) were examined grossly and microscopically between 1973 and 1977 in a 2104 ha. preserve. Prevalence of infection significantly increased from 26.6% of the sample in 1973 to 64.3% in 1975 (P less than .05). A decline to 47.7% in 1977 (P greater than .05) was not significant. However, the number of clinical cases was significantly higher in 1976-1977 (P less than .02) than previously reported in 1973-1975.
1973年至1977年期间,在一个2104公顷的保护区内,对87个取自马鹿和赤鹿(鹿属)的大脑进行了大体和显微镜检查。感染率从1973年样本的26.6%显著上升至1975年的64.3%(P<0.05)。1977年降至47.7%(P>0.05),差异不显著。然而,1976 - 1977年临床病例数显著高于1973 - 1975年之前报告的数量(P<0.02)。
