后元线虫科广州管元线虫(Angiostrong-yius cantonensis)是寄生于野鼠肺内的一种动物寄生虫。人因接触幼虫寄生的中间宿主如螺类等而感染,侵入人体的幼虫移行至中枢神经系统后就表现为以嗜酸粒细胞增多为主要特征的嗜酸粒细胞增多性脑膜脑炎(以下简称“酸脑”)。这类疾病在一些东南亚国家和太平洋区域岛屿上呈散在性或暴发性流行由来已久。以前因认识不足,大多数病例误诊或漏诊。近10多年来因引起重视,报道日益增多。管元线虫也存在于我国,并在我国广东最先发现,但至今国内尚未见到临床病例报告。现将国外资料综述如下: Post-Nematoda Angiostrong-yius cantonensis is an animal parasite that parasites in the voles of wild rodents. Infected by contact with the intermediate host parasitic larvae such as snails, etc., invade the human larva migrate to the central nervous system after the performance of eosinophilia is characterized by eosinophilic meningoencephalitis (hereinafter referred to as “Acid brain”). It has been a long-standing epidemic or outbreak of these diseases on some Southeast Asian countries and Pacific islands. In the past, due to lack of understanding, most cases were misdiagnosed or missed. Over the past 10 years due to attention, reported increasing. Guan Yuan nematodes also exist in our country, and first discovered in Guangdong, China, but so far no clinical case reports have been seen in China. Now foreign materials summarized as follows:
