Using the indirect fluorescent antibody test and sera from 10 proved cases of invasive amoebiasis, the effects of absorption of IgG on observed titres of amoeba-specific IgM and IgA were investigated. In addition, results of cellulose acetate precipitin tests were compared with anti-amoebic antibody levels. Antiamoebic IgM was found at titres of 1:14 to 1:112 after IgG absorption in four cases. Anti-amoebic IgA was detected in sera from four cases, but the maximum titre was 1:28. There was no relationship between the presence of amoeba-specific IgM or IgA and the result of the precipitin test, but a raised anti-amoebic IgG level was consistently found where the precipitin test was positive. However, sera with raised amoeba-specific IgG levels did not invariably give a positive precipitin reaction.
利用间接荧光抗体试验以及来自10例确诊侵袭性阿米巴病患者的血清，研究了IgG吸收对观察到的阿米巴特异性IgM和IgA滴度的影响。此外，还将醋酸纤维素沉淀试验结果与抗阿米巴抗体水平进行了比较。在4例患者中，IgG吸收后抗阿米巴IgM的滴度为1:14至1:112。在4例患者的血清中检测到抗阿米巴IgA，但最高滴度为1:28。阿米巴特异性IgM或IgA的存在与沉淀试验结果之间没有关系，但沉淀试验呈阳性时，抗阿米巴IgG水平始终升高。然而，抗阿米巴IgG水平升高的血清并非总是产生阳性沉淀反应。
