We report a rapid competitive enzyme-linked immunosorbent assay to screen Salmonella typhimurium strains for cholera-related enterotoxin antigens. Polymyxin B extracts of bacterial cells from syncase-glucose broth cultures of 7 of 15 strains gave positive results. The specificity of the test was confirmed with known heat-labile-enterotoxin-positive and -negative Escherichia coli strains which gave significantly different values.
我们报告了一种快速竞争性酶联免疫吸附测定法,用于筛选鼠伤寒沙门氏菌菌株中的霍乱相关肠毒素抗原。15株菌株中的7株在合酶 - 葡萄糖肉汤培养物中的细菌细胞多粘菌素B提取物检测结果呈阳性。用已知的热不稳定肠毒素阳性和阴性大肠杆菌菌株进行验证,结果显示有显著差异,从而证实了该测试的特异性。
