裂头蚴是曼氏迭宫绦虫的幼虫,白色长带形,约300×0.7毫米,头端膨大,中央有一明显的凹陷,具有与成虫相似的头节,但体不分节,只是体表具有不规则横皱褶,后端多呈钝圆形。活时收缩力很强,可在蛙、蛇或人体内寄生。在蛙中多寄生在大腿肌肉间隙里,在蛇中多寄生在皮下。在人体可在眼、皮下、口腔倾面部、脑甚或内脏等多处寄生导致曼氏裂头蚴病,其危害的严重性可因裂头蚴在体内移行及寄生部位的不同而不同。本病分布较广,亚洲、非洲、澳洲以及发达的欧美均有记录。我国人体感染的裂头蚴病散在于广东、浙江、福建、四川等18个省、市、自治区,感染年龄自2.5～62岁,以20～50岁为多,男女比例为2∶1。 人体感染裂头蚴病的途径和方式有以下三种:1、局部贴敷生蛙肉、蛙皮,这是主要的感染方式。我国许多地方流传蛙有“清热解毒、败火祛
Spider larvae are larvae of the manstrichial tapeworm, white long-banded, ca. 300 × 0.7 mm, with an enlarged head at the center with an obvious concavity in the center, similar to an adult’s head, but the body has no knuckles, but the body surface has no Rule horizontal folds, back-end mostly blunt round. Contractility is very strong when live, in frogs, snakes or parasites in the human body. In the frog parasitic in the thigh muscle space, more parasites in the snake subcutaneous. In the human body can be in the eyes, subcutaneous, oral leaking facial parts, brain or internal organs and other parasitic causes Mannich’s sparganosis, the seriousness of the harm may be due to the migration of spider caterpillars in vivo and parasitic sites vary. The disease is widely distributed in Asia, Africa, Australia and developed Europe and the United States have records. Sporadic lacteal disease in China is scattered in 18 provinces, cities and autonomous regions in Guangdong, Zhejiang, Fujian and Sichuan. The age of infection is from 2.5 to 62 years old, with the ratio of male to female being 2: 1. Pathogenesis of human infection sparganosis in the following three ways: 1, the local application of raw frog, frog skin, which is the main way of infection. Spread frogs in many parts of our country have "detoxification, defeat fire cured
