摘　　要：目的了解广州北郊新丰县并殖吸虫自然流行分布状况。方法在调查点山溪中捕捉溪蟹,解剖查找并殖吸虫囊蚴。用检获囊蚴饲喂人工感染家猫,检查感染家猫粪便找虫卵,解剖人工感染虫卵检查阳性家猫,查找并殖吸虫成虫。结果蟹体斯氏狸殖吸虫囊蚴感染率:61.40%(35/57)。感染度:2.23个囊蚴/只蟹,0.44个囊蚴/克蟹。蟹种为平远南海溪蟹。解剖两只人工感染阳性猫检获卫氏并殖吸虫成虫12条。结论广州北郊新丰县斯氏狸殖吸虫中度自然疫源地(Ⅲ级)。斯氏狸殖吸虫是我国主要致病并殖吸虫,该疫源地存在是一个潜在公共卫生危害地,必须引起高度重视。Objective To determine the distribution of paragonimus infection in Xinfeng County located in the north suburban Guangzhou.Methods Freshwater crabs were collected from a site in north suburban Guangzhou to evaluate paragonimus prevalence.Paragonimus metacercariae from infected crabs were used to artificially infect domestic cats and conduct stool surveys,and the recovered adult worms were isolated from cats whose stool samples had paragonimus eggs.Results While the natural infection rate of Pagumogonimus skrjabini in the crabs was 61.40% （35/57）,the number of metacercariae per infected crab and per gram infected crab were 2.23 and 0.44,respectively.The infected crabs were identified as Nanhai potamon pingyuanense.A total of 12 adult worms of Pagumogonimus skrjabini were found from two positive cats artificially infected with detected metacercariae.Conclusion Our analysis revealed an endemic focus of Pagumogonimus skrjabini in Xinfeng County located in the north suburban of Guangzhou.Public awareness and advocacy are needed to draw attention to this new endemic focus since it poses a potential health problem of Pagumogonimus skrjabini,one of the most predominant species of known to cause paragonimiasis in China.
