The mouse adrenal tumor cells (Y-1 strain) and the Chinese hamster ovary cells, two routinely used tissue culture assays for Escherichia coli heat-labile enterotoxin (LT), were used to detect serum antitoxin responses in culture-positive patients from several well-defined sources. There was no correlation between a significant antitoxin response and isolation of LT-producing E. coli in two "domestic" diarrheal outbreaks. Serum samples from a third group of individuals in a rural cholera-endemic area consistently demonstrated significant rises in neutralizing antibody to LT.
小鼠肾上腺肿瘤细胞(Y - 1株)和中国仓鼠卵巢细胞是两种常用于检测大肠杆菌不耐热肠毒素(LT)的组织培养分析方法,被用于检测来自几个明确来源的培养阳性患者的血清抗毒素反应。在两次“家庭内”腹泻暴发中,显著的抗毒素反应与产LT大肠杆菌的分离之间没有相关性。来自霍乱流行农村地区第三组个体的血清样本始终显示出针对LT的中和抗体显著升高。
