Objective A field investigation of worm eggs in dog feces,classification of crabs and metacercaria infection were carried out in Nanbai Town of Zunyi County,Guizhou Province.Methods One or two villages were selected as the survey sites in Nanbai Town of Zunyi County and the local dogs and crabs were chosen as survey objects.Worm eggs in dog feces were detected using natural precipitation method.On the base of holotype,the classification of crabs was identified.Then,crabs were mashed and metacercaria were detected.Results From November 2014 to September 2015,through this survey in Xiejia Village and Longquan Administration Village,fifty-three fresh feces of dogs were collected and three worm eggs were detected,such as Dipylidium caninum egg,Toxocara canis egg and Spirometra mansoni egg.Forty-two crabs were caught,including fourteen female adults (two larvaes) and twenty-eight male adults (nine larvaes).All these crabs were identified as Sinopotamonzunyiense by morphological method and metacercaria was not detected.Conclusion Nanbai Town of Zunyi County only has Sinopotamonzunyiense;metacercaria is not detected,which means that this local area is not a Paragonimus epidemiological region;only three worm eggs are detected in dog feces.%目的 调查贵州省遵义县南白镇家犬蠕虫卵感染情况、溪蟹种类及携带肺吸虫囊蚴情况.方法 2014年11月至2015年9月,选择遵义县南白镇谢家村和龙泉行政村作为调查点,以当地家犬和溪蟹为对象,采用自然沉淀法检查家犬粪便蠕虫卵;基于模式标本Holotype,基础鉴定溪蟹种类;捣碎溪蟹,光镜下检测肺吸虫囊蚴.结果 共采集家犬新鲜粪便53份,检出犬复孔绦虫卵、犬弓首蛔虫卵、曼氏迭宫绦虫卵,共3种蠕虫卵.共捕捉溪蟹42只(雌性14只,含幼体2只;雄性28只,含幼体9只),均为遵义华溪蟹,肺吸虫囊蚴检测均为阴性.结论 遵义县南白镇仅存在遵义华溪蟹,种类较单一;溪蟹中未查见肺吸虫囊蚴,提示当地不属于肺吸虫病流行区;家犬粪便仅查获3种蠕虫卵.
