体内外的寄生虫中,有多种可引起宿主皮肤损害,本文对可引起皮肤病的寄生虫种概述如下: 一、原虫引起的皮肤病: 和医学有关的原虫虽有好多种,但引起皮肤病的并不多(见附表)。其致病机制:(1)媒介昆虫的直接接种:如当感染性的后循环锥虫随采采蝇的唾液侵入人体后,可在皮肤里停留1～2星期,直接引起局部的炎症反应,称“锥虫性下疳”;(2)原虫的直接扩散,如滴虫性外阴瘙痒症,阿米巴脓肿向皮肤破溃;(3)经淋巴液或血液的转移,可形成许多结节,如扩散型皮肤利什曼
In vivo and in vitro parasites, a variety of host skin lesions can cause damage, this article can cause skin diseases parasite species are summarized as follows: First, the protozoa caused by skin diseases: and medical-related protozoa Although there are many, but cause the skin Not many illnesses (see attached table). Its pathogenesis: (1) direct inoculation of vector insects: such as when the infectious retrovirus trypanosomes with tsetse saliva invade the human body, can stay in the skin for 1 to 2 weeks, a direct result of the local inflammatory response, (2) the direct spread of protozoa, such as trichomonas genital pruritus, amoeba abscess to the skin ulceration; (3) the lymph or blood can be transferred to form many nodules, Such as proliferation of skin Leishman
