The recent development of a sensitive and specific test (Enzyme-linked immunosorbent assay) for Toxocara canis infection has made it possible to study the epidemiology of this parasite in man. Antibody to Toxocara was measured in veterinarians, kennel workers, nurses, laboratory technicians, and clerical personnel in an animal hospital (Animal Medical Center, New York, NY) in order to determine the risk of infection in persons with varying degrees of occupational and home exposure to pet dogs. Antibodies were found in 8 (11 per cent) of 73 employees, and the prevalence and intensity of antibody was not statistically associated with either job exposure or dog ownership. However, antibody was not detected in any of the 14 employees who denied both past and present dog ownership. Additional studies using larger numbers of sera are required to determine the significance of these findings.
最近针对犬弓首蛔虫感染研发出了一种灵敏且特异的检测方法（酶联免疫吸附测定法），这使得研究该寄生虫在人类中的流行病学情况成为可能。为了确定在职业和家庭中与宠物狗接触程度不同的人群的感染风险，我们对纽约动物医疗中心的兽医、犬舍工作人员、护士、实验室技术员以及文职人员进行了犬弓首蛔虫抗体检测。在73名员工中，有8人（11%）检测出抗体，抗体的流行率和强度与工作接触或养狗情况均无统计学关联。然而，在14名既否认过去也否认现在养狗的员工中，未检测到任何抗体。需要使用更多血清样本进行进一步研究，以确定这些发现的意义。
