在广西那坡县并殖吸虫流行区，从采集的弯肢溪蟹中发现异盘并殖吸虫囊蚴感染率达９８．５０％（１９７／２００），平均含囊蚴数——每蟹、每克分别是１２９．２３个、４．６１个。有一只４７克重雄蟹含囊蚴６６５３个，为目前最高纪录。按疫区等级划分，属超高度并殖吸虫疫源地。经统计学分析，两性溪蟹的感染度（每蟹含囊蚴数）随体重的增加而呈上升趋势，有显著差异（Ｐ＜０．０５），而感染率、每克含囊蚴数均与体重、性别无明显关系（Ｐ＞０．０５）。囊蚴在蟹体的分布，以鳃叶最多（３２．４４％），其余依次是头胸肌（２４．４３％）、步足（２５．２２％）、螯肢（７．２２％）、内脏（６．４５％）、肝（２．４８％）和腹部（０．７６％）。上述各部位的感染率依次是：１００％、９７．９７％、９４．９２％、８３．７６％、８５．２８％、７０．５６％和４４．６７％
In Pampaii prevalence area in Napo County, Guangxi Province, the infection rate of Paragonimus erythraea was 98.50% (197/200). The mean number of metacercariae - per crab, Each gram is 129.23, 4.61. A 47 gram male crabs with 6653 metacercariae, is currently the highest record. Divided by the epidemic area, is a high degree of paragonimiasis foci. The statistical analysis showed that the infection rate (cercariae per crab) of C. sexta had an upward trend with the increase of body weight (P <0.05), while the infection rate, number of cercariae per gram No significant relationship with body weight and gender (P> 0.05). The distribution of metacercariae in the crab body was the highest (32.44%), followed by the head and chest muscle (24.43%), walking foot (25.22%), chelonian (7.22%), (6.45%), liver (2.48%) and abdomen (0.76%). The infection rates of the above parts were as follows: 100%, 97.97%, 94.92%, 83.76%, 85.28%, 70.56% and 44.67%
