A seroepidemiological survey for toxocaral infection was performed using samples from children and adult women in the Yamaguchi area of Western Japan. An enzyme-linked immunosorbent assay using excretory--secretory antigen was applied to these sera. Of samples tested, 3.1% from children and 3.7% from women were positive. It was found that regression analysis of positive rates by age between 20 and 70 or more years was significant in the positive direction. The positive rates from urban, rural and fishing areas were 5.7, 3.9 and 1.7% respectively. Also, the rates from northern, western and eastern parts in the research area were 5.7, 4.7 and 0.5% respectively. These findings suggested that environmental factors are important for toxocaral infection. Further, the rate for 108 samples who answered that they have owned dogs was 6.2% compared to 2.9% of 422 respondents who denied an experience of owning dogs. This fact suggested that attention should be paid to dog breeding for prevention and control of toxocaral infection in man.
在日本西部山口地区，对儿童和成年女性的样本进行了弓首蛔虫感染的血清流行病学调查。对这些血清采用了使用排泄-分泌抗原的酶联免疫吸附测定法。在所检测的样本中，儿童样本的阳性率为3.1%，女性样本的阳性率为3.7%。研究发现，20岁至70岁及以上人群的阳性率按年龄进行回归分析呈显著的正向关系。城市、农村和渔业地区的阳性率分别为5.7%、3.9%和1.7%。此外，研究区域北部、西部和东部的阳性率分别为5.7%、4.7%和0.5%。这些发现表明环境因素对弓首蛔虫感染很重要。此外，在108名回答养过狗的受访者中，阳性率为6.2%，而在422名否认有养狗经历的受访者中，阳性率为2.9%。这一事实表明，在预防和控制人类弓首蛔虫感染方面，应关注养狗问题。
