Tsuji和Yokogawa(1972)应用免疫扩散和免疫电泳方法证明日本血吸虫盐水粗提物不仅与同属的曼氏血吸虫具有共同抗原成分,而且与其它吸虫,如并殖吸虫、肝片形吸虫、华枝睾吸虫等,甚至与某些绦虫及线虫,也具有共同抗原成分。该报告未见姜片虫有关资料。国内近年有不少报道血吸虫病免疫诊断中与姜片虫感染有不同程度交叉反应。本院寄生虫学教研室(1979)作间接血凝(抗原为血吸虫卵冷浸液),与姜片虫感染者血清交叉反应率为12～21.6%,血吸虫皮试(抗
Tsuji and Yokogawa (1972) demonstrated that the crude extract of Schistosoma japonicum has not only common antigen components with Schistosoma mansoni belonging to the same genus, but also with other flukes, such as Paragonimus, Hepatitis schistosomica, and WCS. Flukes, etc., and even some aphids and nematodes also have common antigenic components. The report did not see any information on ginger insects. In recent years, many domestic reports of schistosomiasis immunodiagnosis have different degrees of cross-reaction with ginger insect infections. The parasitology department of the hospital (1979) used indirect hemagglutination (antigen is a cold immersion of schistosome egg), and the serum cross-reactivity rate between the infected and ginger insects was 12 to 21.6%. The schistosomiasis skin test (resistance
