蠊缨滴虫(Lophomomas blattarum)是一种动物源性寄生原虫,由其引起人体感染的案例之前偶有报道[1],近年来呈上升趋势,但其流行规律、传播途径、致病机制目前尚不明确。宁波市医疗中心李惠利医院在不足半年时间内,发现4例蠊缨滴虫引起的肺部感染,现结合文献,对案例进行讨论。 Lophomomas blattarum is an animal-derived parasitic protozoal that has occasionally been reported occasionally for human infections [1] and has been on the rise in recent years, but its prevalence, route of transmission and pathogenesis are currently still uncertain. In less than half a year, Li Huili Hospital of Ningbo Medical Center found 4 cases of pulmonary infection caused by Trichomonas aeruginosa. Now, with reference to the literature, the case is discussed.
