| 本文报告广东梅县地区(七县市)1982~84年肺吸虫病流行病学调查概况。结果证实梅县地区的一些山区为广东省肺吸虫病的流行区。查实1科2种的淡水螺类、2科2种的淡水蟹类、2科3种的食肉类动物为流行区肺吸虫的第一、第二中间宿主和保虫宿主,其肺吸虫的携带率分别为0.18%(40/22,015)、62.0%(589/950)、47.6%(20/42)。人群肺吸虫抗原皮试阳性率平均为6.6%(512/7,738),以男性和青少年儿童(5~30岁)较高。流行区致病虫种主要为卫氏肺吸虫。台湾南海溪蟹首次在广东发现,其作为卫氏肺吸虫和三平正肺吸虫的第二中间宿主,尚属国内第一次证实。 |

| A general epidemiological survey of paragonimiasis in Meixian county, Guangdong Province in the period from 1982 to 1984 was reported. It showed that certain mountainous regions in this county are endemic areas and that two species of the freshwater snails of same family accounted for the first intermediate hosts and two species of the freshwater crabs in different families are the second intermediate hosts. Another three species of carnivore (term) belonging to two families acted as the final hosts. The infection rates of them were found to be 0.18% (40/22,015), 62.0% (589/950) and 47.6% (20/42). As shown by the intradermal tests made on 7,738 persons with crude antigen of adult paragonimus, there were 512 positives (6.6%) in the chosen endemic area. The positive rate of men was higher than women and the 5~30 age group was higher than others. The common species of paragonimus in this area were Paragonimus westermani Kerbert, 1878. In the survey, we have found Nanhaipotamon formosanin Parisi, 1916 which had never been reported in Guangdong Province, and it was the first time in China to show that the Nanhaipotamon formosanin Parisi, 1916 in the second intermediate host of Paragonimus Westermani and Euparagonimus cenocopiosus Chen, 1962. |
