以免疫单扩散法和ABC－ELISA法测定50名在校大学生钩虫感染者血清的IgG、IgA、IgM和IgE水平，并比较不同感染度和男女人群间的差异。结果表明，钩虫感染者血清IgA、IgM与对照组接近，而IgG和IgE则显著高于对照组。中、重度感染者增高的程度甚于轻度感染者，提示虫体负荷与抗体水平具有一定的相关关系。感染者IgE均值较高，可能还与宿主对其它未知的混合性抗原发生反应有关。
The levels of IgG, IgA, IgM and IgE in sera of 50 university students with hookworm infection were measured by immunodominant diffusion assay and ABC-ELISA. The differences in infection rates and differences between men and women were compared. The results showed that the hookworm infection serum IgA, IgM and control group close, while IgG and IgE was significantly higher than the control group. Moderate and severe infections increased more than mild infections, suggesting that parasites load and antibody levels have a certain correlation. Infected with higher mean IgE may also be the host of other unknown mixed antigens on the reaction.
