【摘要】 目的　探讨改进检测肠毒性大肠菌不耐热肠毒素的方法。方法　采用改进平板免疫溶血试验方法并建立微量被动免疫溶血试验法。结果　微量被动免疫溶血试验和平板免疫溶血试验敏感度一致。结论　微量被动免疫溶血试验比平板免疫溶血试验法简化了试验步骤,节约时间,并保留了原方法敏感度高、结果易判断的优点。更多还原

【Abstract】 Objective To improve the testing method for heat-liable enterotoxin(LT) of ETEC. Methods To alter plate immunohemolytic test for LT .Results The sensitivity of micro-impassive-immunohemolytic test is equal to plate imnunohemolytic test.Conclusion The micro-impassive immunohemolytic test is more simple, less time and easier to judge than plate immuohemolytic test.更多还原
