Abstract

Specificities of Japan by geography, culture, and low incidence for Toxoplasmosis were examined in this epidemiological study. 1 731 human sera were examined by several immunological tests but these results are related with Agglutination-Latex test. The sera came from North (Hokkaido), Middle (Tokyo area) and South (Okinawa). The ratio for the whole Japan towards Toxoplasmosis is 24.7% but the increase of antibodies with age is late: rate of positivity 4.6% up to 17 years old and nearly 30% after 30 years old. Cats, business, climate do not seem to influence the human infection. It is consumption of meat and particularly raw meat which influence the results: 40.8% positive results among eaters of raw meat and 22% among those not eating meat or eating it well cooked.

摘要

在这项流行病学研究中，对日本在地理、文化以及弓形虫病低发病率方面的特异性进行了调查。通过多种免疫学检测对1731份人体血清进行了检测，但这些结果与胶乳凝集试验相关。血清来自北部（北海道）、中部（东京地区）和南部（冲绳）。全日本弓形虫病的感染率为24.7%，但抗体随年龄增长的上升较晚：17岁以下阳性率为4.6%，30岁以后接近30%。猫、职业、气候似乎并不影响人类感染。影响检测结果的是肉类消费，尤其是生肉：食用生肉者的阳性结果为40.8%，不食用肉类或食用熟透肉类者的阳性结果为22%。
