虱病疾病描述

来源:华人健康网 | 发布时间:2010-12-17 10:55:56 | www.chinesejk.com
虱属于昆虫纲,虱目,是体外寄生虫,种类很多,如人虱、牛虱、狗虱、猪虱、鸡虱、鸭虱、猫虱、鼠虱,分别寄生在人和动物的体表。根据口器构造与取食习性可分两大类:一类为刺吸型口器,以刺吸人和动物血为食,又称吸虱,如人虱、牛虱;另一类是咀嚼型口器,以皮屑、羽毛为食,称啮虱,如鸡虱、鸭虱等。吸虱均寄生于哺乳动物。
虱叮刺皮肤所引起的皮肤病称虱咬症,或称虱病。虱叮咬皮肤不仅引起皮肤损害,而且又是斑疹伤寒、回归热、战壕热等传染病的媒介。
虱发育过程分卵、稚虫(又称若虫)、成虫三个时期。人虱可产卵300个左右,寿命30~60 d。
