Sera collected from 2,564 inhabitants of different areas in Hyogo Prefecture, Japan, were examined for antibody to Toxoplasma gondii by enzyme-linked immunosorbent assay. The overall prevalence rates of male (11.6%) and female populations (7.6%) were significantly different (P < 0.001). The prevalence also depended on age of the population. Of 11 districts three, being far from the sea and occupied mainly by mountains with relatively high altitudes (95-195 m), showed a significantly lower average prevalence (5.0%) than the other districts with altitudes of 3-58 m, a part of which was adjacent to the sea (10.6%; P < 0.001). The average prevalence obtained in two districts with annual rainfall of 1,862-2,062 mm (16.8%) was significantly higher than that obtained in six districts with annual rainfall of 1,026-1,204 mm (8.6%; P < 0.001).
对从日本兵库县不同地区的2564名居民采集的血清进行了酶联免疫吸附测定，以检测弓形虫抗体。男性（11.6%）和女性人群（7.6%）的总体患病率存在显著差异（P<0.001）。患病率还取决于人群的年龄。在11个区中，有3个区远离大海，主要为海拔相对较高（95 - 195米）的山区，其平均患病率（5.0%）显著低于其他海拔为3 - 58米且部分与海相邻的区（10.6%；P<0.001）。年降雨量为1862 - 2062毫米的两个区的平均患病率（16.8%）显著高于年降雨量为1026 - 1204毫米的六个区（8.6%；P<0.001）。
