目的评价旋毛虫肌幼虫排泄分泌(excretory-secretory,ES)抗原诊断早期旋毛虫病的价值。方法应用旋毛虫肌幼虫ES抗原Western blot对旋毛虫感染后6~11d的小鼠血清及19d的早期旋毛虫病人血清进行检测,并与感染后35d的晚期旋毛虫病人和其他...目的评价旋毛虫肌幼虫排泄分泌(excretory-secretory,ES)抗原诊断早期旋毛虫病的价值。方法应用旋毛虫肌幼虫ES抗原Western blot对旋毛虫感染后6~11d的小鼠血清及19d的早期旋毛虫病人血清进行检测,并与感染后35d的晚期旋毛虫病人和其他寄生虫病人血清的检测结果进行比较。结果 Western blot分析显示,肌幼虫ES蛋白中的2条蛋白带(41.5、55kDa)可被旋毛虫感染后7~11d的小鼠血清识别,6条蛋白带(41.5、44.1、45、55、61和65.2kDa)能被早期和晚期旋毛虫病人血清识别,阳性反应率均为100%(15/15);这6条蛋白带与裂头蚴病人和健康人血清无交叉反应,但与其他寄生虫病(血吸虫病、并殖吸虫病、华支睾吸虫病、棘球蚴病及囊尾蚴病)患者血清具有明显的交叉反应(19.12%~38.23%)。结论旋毛虫肌幼虫ES抗原中的41.5kDa^65.2kDa蛋白带可与旋毛虫感染早期血清反应,但与其他蠕虫病患者有明显的交叉反应。展开更多
