A seroprevalence study of cysticercosis, Trypanosoma cruzi, and plasmodia species and screening for active malaria was conducted among a randomly selected group of 138 Hispanic and Haitian migrant farmworkers. A random sample of labor camps in eastern North Carolina was selected. Blood samples were tested by Indirect Fluorescent Antibody techniques for plasmodial antibody and by enzyme-linked immunosorbent assay (ELISA) for cysticerci and T. cruzi antibodies. Questionnaires collected demographic data and medical history of the workers and family. Blood films stained with Leukostat stain were examined for plasmodia species. The seroprevalence of cysticercosis was 10 percent, T. cruzi 2 percent, and plasmodia species 4.4 percent. One case of active malaria (Plasmodium vivax) was demonstrated. The clinical significance of seropositivity was not determined, but these results suggest that a small but significant number of farmworkers are infected with cysticercosis, T. cruzi, and malaria. Migrant health clinicians should be aware of the possible presence of these infections. Greater observance and enforcement of sanitation regulations in farmwork is needed to prevent transmission of cysticercosis.
在随机抽取的138名西班牙裔和海地流动农场工人中开展了一项关于囊尾蚴病、克氏锥虫、疟原虫种类以及活动性疟疾筛查的血清流行率研究。研究选取了北卡罗来纳州东部的劳动营作为随机样本。采用间接荧光抗体技术检测血样中的疟原虫抗体，采用酶联免疫吸附测定（ELISA）检测囊尾蚴和克氏锥虫抗体。通过问卷调查收集工人及其家属的人口统计学数据和病史。用白细胞染色剂染色的血涂片用于检查疟原虫种类。囊尾蚴病的血清流行率为10%，克氏锥虫为2%，疟原虫种类为4.4%。发现1例活动性疟疾（间日疟原虫）病例。血清阳性的临床意义尚未确定，但这些结果表明，有一小部分但数量可观的农场工人感染了囊尾蚴病、克氏锥虫和疟疾。流动健康临床医生应意识到这些感染可能存在。需要加强对农场工作卫生法规的遵守和执行，以预防囊尾蚴病的传播。
