A survey was performed to investigate the infection status of fishborne trematode (FBT) metacercariae in freshwater fish from Guangxi Zhuang Autonomous Region, China. A total of 307 freshwater fish of 31 species were collected from 5 administrative regions of Guangxi Zhuang Autonomous Region. They were examined by artificial digestion method from July 2003 to August 2004. No metacercariae were detected in fish from Fusui-xian. In fish from Mashan-xian and a market in Nanning, 3 species of metacercariae, Haplorchis taichui, Haplorchis pumilio, and Centrocestus formosanus, were mainly detected. Metacercariae (8 in number) of Clonorchis sinensis were found in 1 Chanodichthys dabryi purchased from a market in Nanning. In fish from Yangshuo, Metagonimus yokogawai metacercariae were detected from all 18 fish species examined. Total 13 C. sinensis metacercariae were found in 3 out of 10 Hemibarbus maculatus from Yangshuo. All 7 Zacco platypus from Yangshuo were infected with 8-112 Echinochasmus perfoliatus metacercariae. In fish from Binyang-xian, H. pumilo metacercariae were mainly detected in all 5 fish species examined, and only 1 metacercaria of C. sinensis was found in a Hemiculter leucisculus. From the above results, it was confirmed that some species of freshwater fish play a role of second intermediate hosts for FBT in Guangxi Zhuang Autonomous Region, China. In particular, 4 species of intestinal flukes, M. yokogawai, H. taichui, H. pumilio, and C. formosanus, were prevalent in fish hosts, whereas C. sinensis metacercariae were detected only in 3 fish species.
为调查中国广西壮族自治区淡水鱼体内食源性吸虫(FBT)囊蚴的感染状况,从广西壮族自治区5个行政区共采集了31种307尾淡水鱼,并于2003年7月至2004年8月采用人工消化法进行检测。扶绥县的鱼未检测到囊蚴。在马山县和南宁市某市场的鱼中,主要检测到3种囊蚴,即泰氏嗜眼吸虫、微小嗜眼吸虫和台湾棘带吸虫。从南宁市某市场购买的1尾达氏鲌体内发现8枚华支睾吸虫囊蚴。在阳朔县的鱼中,所检测的18种鱼均发现了横川后殖吸虫囊蚴。阳朔县10尾斑条花鳅中有3尾发现了总计13枚华支睾吸虫囊蚴。阳朔县所有7尾宽鳍鱲均感染了8 - 112枚叶形棘隙吸虫囊蚴。在宾阳县的鱼中,所检测的5种鱼均主要检测到微小嗜眼吸虫囊蚴,仅在1尾麦穗鱼中发现1枚华支睾吸虫囊蚴。从上述结果证实,中国广西壮族自治区部分淡水鱼种类可作为食源性吸虫的第二中间宿主。特别是,4种肠道吸虫,即横川后殖吸虫、泰氏嗜眼吸虫、微小嗜眼吸虫和台湾棘带吸虫在鱼类宿主中普遍存在,而华支睾吸虫囊蚴仅在3种鱼中被检测到。
