目前,用于血吸虫病免疫诊断的最常用的抗原是成虫抗原和虫卵抗原,由于这两种粗抗原的成分复杂,且与其他寄生虫感染血清存在着较严重的交叉反应,血吸虫病诊断的特异性不高,生产的试剂不宜标准化。近年来,随着分子生物学的迅猛发展,很多生物学技术已经用于寄生虫学(病)研究。运用分子克隆等技术可以获得大量纯化的
At present, the most commonly used antigens for immunodiagnosis of schistosomiasis are adult and egg antigen, which have complex cross-reactivity with other parasite-infected sera due to the complex composition of the two crude antigens. The diagnosis of schistosomiasis Specificity is not high, the production of reagents should not be standardized. In recent years, with the rapid development of molecular biology, many biological techniques have been used in parasitology (disease) research. The use of molecular cloning and other techniques can be a large number of purified
