Abstract：
Intestinal trematodes are among the most common types of parasitic worms. About 76 species belonging to 14 families have been recorded infecting humans. Infection commonly occurs when humans eat raw or undercooked foods that contain the infective metacercariae. These parasites are diverse in regard to their morphology, geographical distribution and life cycle, which make it difficult to study the parasitic diseases that they cause. Many of these intestinal trematodes have been considered as endemic parasites in the past. However, the geographical limits and the population at risk are currently expanding and changing in relation to factors such as growing international markets, improved transportation systems, new eating habits in developed countries and demographic changes. These factors make it necessary to better understand intestinal trematode infections. This chapter describes the main features of human intestinal trematodes in relation to their biology, epidemiology, host-parasite relationships, pathogenicity, clinical aspects, diagnosis, treatment and control.
摘要：
肠吸虫是最常见的寄生虫类型之一。已记录到感染人类的约76种，属于14个科。感染通常发生在人类食用生的或未煮熟的食物时，这些食物含有感染性的con虫。这些寄生虫在形态上是多样的,地理分布和生命周期，这使得研究它们引起的寄生虫病变得困难。过去，许多这些肠道吸虫被认为是地方性寄生虫。然而,地理界限和面临风险的人口目前正在随着国际市场增长等因素而扩大和变化，改善运输系统，发达国家的新饮食习惯和人口变化。这些因素使得有必要更好地了解肠道吸虫感染。本章描述了人类肠道吸虫的主要特征与其生物学有关，流行病学,宿主-寄生虫关系，致病性，临床方面，诊断,治疗和控制。
