目的 调查福建省松溪县肺吸虫虫种 ,第一、二中间宿主及其感染率。方法与结果 有两种肺吸虫 ,即斯氏狸殖吸虫和泡囊狸殖吸虫 (经实验动物感染证实 ) ,分布于东部和西部乡村。全县发现福建拟钉螺和放逸短沟蜷两种螺蛳 ,只有前者为斯氏狸殖吸虫和泡囊狸殖吸虫的第一中间宿主 ,其感染率为 0 7% (4/ 5 6 9)。全县有 3种溪蟹 ,即福建华溪蟹、南海角肢溪蟹、福建马来溪蟹 ,其充当第二中间宿主 ,携带斯氏狸殖和泡囊狸殖囊蚴 ,感染率为 5 6 0 6 (37/ 6 6 ) ,平均每只蟹和每g蟹组织携带囊蚴分别为 14 2 2和 1 2 8个。结论 松溪县为福建省北部肺吸虫病高度流行区。斯氏狸殖吸虫为重要致病虫种 ,主要第一、二中间宿主分别为福建拟钉螺和福建华溪蟹。
Objective To investigate the parasites, the first and second intermediate hosts and their infection rate in Songxi County, Fujian Province. Methods and Results There are two types of paragonimiasis, namely, the genus Clostridium spp. And the vesicular colony (confirmed by experimental animal infection), distributed in the eastern and western villages. The county found Fujian snail snail and let go Cairina short groove curled two snail, only the former for the genus Schistis and Epiphyllous oviparous first host, the infection rate was 0 7% (4/5 6 9) . The county has 3 kinds of crabs, that is, Fujian huaxi crabs, South China Cape crab limbs, Fujian Malay crab, which serves as the second intermediate host, carrying Sesbanchia brevis and bursa of genitalium infection rate of 5 6 0 6 (37/6 6), with an average of 14 2 2 and 128 respectively for each crab and each g crab tissue. Conclusion Songxi County is a highly endemic area of paragonimiasis in the northern part of Fujian Province. Trichogramma colony is an important pathogenic species, the main first and second intermediate hosts were Fujian snail and Fujian huaxi crab.
