在体外培养中,非感染者末梢血内的白细胞能粘附于马来丝虫微丝蚴。由于抗体与微丝蚴鞘膜的反应,或由于正常血清中的不耐热因子而促使产生细胞的粘连反应。这种促使产生粘连反应的抗体可能是 IgG 类,因为:1) 用直接免疫荧光表明仅仅从丝虫病人的血清中测得高滴度的 IgG 抗鞘膜抗体;2)加入低浓度的与 IgG Fc 部分结合的葡萄球 In vitro culture, leukocytes in the peripheral blood of non-infected individuals adhere to the microfilariae of Malay filariasis. Due to the reaction of the antibodies with the microfilaria sheath, or due to the non-heat-resistant factors in normal serum, cell adhesion reactions are induced. Such an antibody that causes an adhesion reaction may be of the IgG class because: 1) direct immunofluorescence indicates that only high titers of IgG anti-coat antibodies are measured from the sera of filariasis patients; 2) Fc part-bound grape ball
