近年来我县于夏秋季时有因不明高热而死亡的猪只,这是继1977年上海市猪弓形虫病暴发流行后持续至今的散在发病。为了解我县人群中有否弓形虫感染,我们于1984年9～12月,对密切接触生猪的易感人群进行了调查。 调查对象为本县21个乡镇食品站的屠宰工人122例、肠衣加工工人46例及近年来猪弓形虫病发病率较高的猪饲养场的饲养员64例,共计232例。 In recent years, my county died of unknown heat during the summer and autumn. This is the second consecutive epidemic following the outbreak of swine toxoplasmosis in Shanghai in 1977. In order to find out whether Toxoplasma gondii infection is present in our county population, we conducted a survey in September-December 1984 on susceptible populations closely exposed to live pigs. In the survey, 122 slaughtering workers, 46 cases of cashew workers and 64 pig feeders with a high incidence of pig’s toxoplasmosis were found in 21 township food stations in the county, a total of 232 cases.
