目的:调查广州北部(从化市、增城市、龙门县、新丰县)山区淡水螺、淡水蟹感染并殖吸虫尾蚴、囊蚴的情况,了解并殖吸虫流行分布状况。方法采集山溪螺蛳、溪蟹,检查并殖吸虫尾蚴、囊蚴,鉴定并殖吸虫虫种。结果从化市良口镇螺蛳尾蚴感染率0.32%,螺种为放逸短沟蜷;溪蟹囊蚴感染率100%,蟹种为平和华溪蟹。吕田镇螺蛳尾蚴感染率0.03%,螺种为拟钉螺;溪蟹感染率为36.73%,蟹种为平远南海溪蟹。龙门县南昆山尾蚴感染率0.15%,螺种为放逸短沟蜷;溪蟹囊蚴感染率为100%,溪种为平和华溪蟹。增城市、新丰县各调查点收集的螺蛳、溪蟹均未检测到尾蚴及囊蚴。结论首次发现广州北部山区从化市良口镇、南昆山为卫氏并殖吸虫超高度疫源地(Ⅰ级)。吕田镇为斯氏狸吸虫中度疫源地(Ⅲ级)。
目的:調查廣州北部(從化市、增城市、龍門縣、新豐縣)山區淡水螺、淡水蟹感染併殖吸蟲尾蚴、囊蚴的情況,瞭解併殖吸蟲流行分佈狀況。方法採集山溪螺螄、溪蟹,檢查併殖吸蟲尾蚴、囊蚴,鑒定併殖吸蟲蟲種。結果從化市良口鎮螺螄尾蚴感染率0.32%,螺種為放逸短溝踡;溪蟹囊蚴感染率100%,蟹種為平和華溪蟹。呂田鎮螺螄尾蚴感染率0.03%,螺種為擬釘螺;溪蟹感染率為36.73%,蟹種為平遠南海溪蟹。龍門縣南昆山尾蚴感染率0.15%,螺種為放逸短溝踡;溪蟹囊蚴感染率為100%,溪種為平和華溪蟹。增城市、新豐縣各調查點收集的螺螄、溪蟹均未檢測到尾蚴及囊蚴。結論首次髮現廣州北部山區從化市良口鎮、南昆山為衛氏併殖吸蟲超高度疫源地(Ⅰ級)。呂田鎮為斯氏貍吸蟲中度疫源地(Ⅲ級)。

Objective To investigate the species of freshwater snails, crabs and their natural infection of Paragonimus cercaria, metacercariae in northern suburban of Guangzhou, and understand the distribution of Paragonimus. Methods The freshwater snails and crabs were collected from mountain streams to detect the cercaria and metacercariae of Paragonimus and their identify categories. Results The average infection rate of cercaria in Liangkou town, Lvtian town (Conghua city) and Nankunshan (Longmen county) was 0.32%, 0.15% and 0.03%, respectively. The snail species in both Liangkou town and Nankunshan was identified as Semisulcospira libertina, Tricula in Lvtian town. The average infection rate of metacercariae in Liangkou town, Lvtian town and Nankunshan was 100%, 36.73% and 100%, respectively. The crab species in both Liangkou town and Nankunshan were identified as Sinopotamon pinheense, and Nanhaipotomon pinyuanense in Lvtian town. The cercaria and metacercariae were not found in the samples of freshwater snails and crabs in Zengcheng city and Xinfeng County. Conclusions It,s the first report that Liangkou town and Lvtian town of Conghua city in northern suburban of Guangzhou is the ultra- high infectious focus of Paragonimus westermani infection(GradeⅠ), and Nankunshan town is the moderate infectious focus of Paragonimus skrjabini. (GradeⅢ).
