Abstract

The prevalence of helminths in pigs was investigated in five rural communities situated on the embankment of Dongting Lake in Zhiyang County, Hunan Province, People's Republic of China, in an area known to be endemic for Schistosoma japonicum. The helminth prevalences identified on the basis of faecal egg count analysis were: Oesophagostomum spp. (86.7%), Ascaris suum (36.7%), Metastrongylus spp. (25.8%), Strongyloides spp. (25.8%), Trichuris suis (15.8%), Globocephalus spp. (6.7%), Gnathostoma spp. (4.2%), Schistosoma japonicum (5.0%) and Fasciola spp. (1.3%). Post mortem examinations of a small number of pigs depositing eggs of different helminth species revealed the presence of Oesophagostomum dentatum, O. quadrispinulatum, A. suum, Metastrongylus apri, M. pudendotectus, T. suis, G. hispidum and Ascarops dentata. Prevalences of all helminths, with the exception of Oesophagostomum spp., were higher in young pigs (< 8 months old) compared with adult pigs. Prevalences of trematodes were very low, especially for S. japonicum which had decreased dramatically compared with previous reports from this area of P.R. China, whereas prevalences of nematodes were generally in agreement with those reported from other Yangtze River Provinces. Results from helminth prevalence studies in pigs, conducted in other provinces of P.R. China between 1987 and 1997, are presented and discussed. It was concluded that a government helminth control programme, implemented in 1995 to control S. japonicum infection in pigs in Hunan Province, may have resulted in a greatly reduced prevalence of S. japonicum in pigs in this region.

中华人民共和国洞庭湖区（湖南省）猪蠕虫的流行和分布情况

本研究调查了位于中华人民共和国湖南省益阳市洞庭湖大堤上的五个农村社区（该地区是日本血吸虫的流行区）中猪的蠕虫感染率。根据粪卵计数分析确定的蠕虫感染率为嗜食道真菌（86.7%）、蛔虫（36.7%）、甲线虫（25.8%）、强线虫（25.8%）、猪毛滴虫（15.8%）、球虫（6.7%）、鹅口疮（4.2%）、日本血吸虫（5.0%）和法氏囊虫（1.3%）。对少量沉积有不同蠕虫虫卵的猪进行的死后检查显示，猪体内存在牙形食道寄生虫（Oesophagostomum dentatum）、O. quadrispinulatum、A. suum、Metastrongylus apri、M. pudendotectus、T. suis、G. hispidum 和 Ascarops dentata。与成年猪相比，幼猪（8 个月大）的蠕虫感染率更高，但食道口器虫属除外。震颤线虫的流行率非常低，尤其是日本震颤线虫的流行率与中国该地区以前的报告相比大幅下降，而线虫的流行率与长江其他省份的报告基本一致。本文介绍并讨论了 1987 年至 1997 年期间在中国其他省份进行的猪蠕虫感染率研究结果。结论是，政府于 1995 年在湖南省实施了一项蠕虫控制计划，以控制猪的日本线虫感染，该计划可能已大大降低了日本线虫在该地区猪中的流行率。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
