本文观察了浙南六县浙江华溪蟹体内两种肺吸虫囊蚴的分布情况。证明囊蚴在溪蟹体内的寄生部位因虫种而异。卫氏肺吸虫囊蚴在足、胸肌最多,背壳、内脏等处较少;在足关节附近囊蚴较多,蟹之眼、腮亦可检出。三平正肺吸虫囊蚴主要分布在蟹的心脏。实验表明,寄生在溪蟹体内的囊蚴在蟹体破碎时脱落,易污染水源或餐具造成感染。本文同时就囊蚴在溪蟹体内的分布与脱落情况,与流行病学关系作了初步分析。
This article observed the distribution of two Paragonimus spp in Zhejiang Huaxi crab in six counties of southern Zhejiang. Proved that the metacercaria parasites in the crab body due to different species. Paragonimus westermani metacercaria in the foot, the most pectoralis, dorsal shell, internal organs, etc. less; in the vicinity of the foot joints more metacercaria, crab eye, gills can be detected. Sanping positive Paragonimus larvae are mainly distributed in the heart of crab. Experiments show that the parasites in crab body cercariae shed when the crab broken, easy to contaminate water or tableware cause infection. In the meantime, the etiology and epidemiology of metacercariae in crabs were analyzed.
