湖北省人体寄生虫种类及分布的初步研究

INVESTIGATIONS ON SPECIES AND DISTRIBUTION OF HUMAN PARASITES IN HUBEI PROVINCE, PEOPLES REPUBLIC OF CHINA

按分层整群随机抽样法，调查了湖北省３９个县（市、区），５３２８４人．湖北省人体寄生虫平均感染率５２．０４％，确定的虫种６５种．分布于全省各县（市、区）的虫种１７种，仅见于少数地区极少数人群的少（罕）见虫种１３种．棘口科吸虫、横川后殖吸虫、猫后睾吸虫、异形异形吸虫、小杆线虫、铁线虫、美丽筒线虫和缩小膜壳绦虫等系省内首次报道．寄生虫感染和分布与地理条件、气候、社会经济基础、卫生条件、人群职业、年龄、生活习惯和生产方式等自然和社会因素有关．

persons in 39 counties (cities and districts) were investigated for human parasites by adopting the methods of stratification, clustering,random sampling.The general infection rate of human parasites was 52.04 per cent in Hubei Province. It was assured that 65 species of human parasites were in this province, including 16 species of nematodes, 17 species of protozoa, 11 species of trematodes, 5 species of cestodes and 16 species of medical insects. According to materials new available and the documentes information, there were 15 species of parasites rarely or infrequently seen in this province. It was the first time that Dioctophymma renale, Echinochasmus perfoliatus, Opisthorchis felineus, Metagonimus yokogawai, Rhabditis sp., Gongylongema pulchrum and Chilomastix mesnili were reported in Hubei Province. The distribution of human parasites and the prevalence of parasitic infections are related to natural and social ecological factors. These ecological factors involve topography, height above sea level, longitude and latitude, sunshine, atmospheric temperature, precipitation, relative humidity, social economic base, environmental sanitation, as well as age, occupation, cultural level, mode of production and habits and customs of inhabitants.
