摘要
本文报告刚刺颚口线虫Gnathostoma hispidum和棘颚口线虫Gnathostoma spinigerum流行学和动物实验。证明我国有40种动物充当它们的第一、二中间宿主和转续宿主,其中30种是这两种病源共同宿主。首次报告猕猴Macaca mulatta可作刚刺颚口线虫的第二中间宿主和转续宿主。用刚刺颚口线虫晚第三期幼虫经皮肤感染家猫和小白鼠均得阳性。调查和实验结果表明刚刺颚口线虫和棘颚口线虫的生物学和流行学特性十分相似,显示它们都是人兽共患的寄生虫。文中讨论刚刺颚口线虫的传播途径和人体感染问题。
This paper reports the epidemiology of two species of Gnathostoma, Gnathostonma hispidum and G. spinigerum, and tests of G. hispidum larvae in animals. The examinations and experimental studies found that in China, 40 species of animals served as the first and second intermediate hosts and paratenic hosts of these parasites. Among them, 30 species are common hosts of both G. hispidum and G. spinigerum. Our test has first proved that Macaca mulatta can be infected with both the early 3rd-stage larvae of G.hispidum in cyclops and the advanced 3rd-stage larvae in the fish, thus acting as both second intermediate host and paratenic host. The domestic cat and white mouse were experimentally made on the intact and acratched skin penetration thorugh using both the early 3rd-stage larvae in cyclops and the advanced 3rd-stage larvae in fish. The results were all positive, but only the advanced 3rd-stage larvae obtained from the fish possessed the powe of infectivity. The surveys of epidemiology and tests of animals showed that the characters of epidemiology and biology of G. hispidum were quite similar to G. spinigerum. By this reason, the authors believe that human may be infected by eating uncooked vertebrate hosts containing G. hispidum larvae or drinking water carrying the larvae in cyclops.Comments are made as regards the methods of trasmission and human infection of G.hispidum.
