For direct identification of toxigenic colonies ofClostridium botulinum type E, suspected colonies are uniformly suspended in a phosphate buffer containing 0.5% (w/v) gelatin and 0.05% (w/v) Tween 20. After centrifuging, the supernatant is tested for botulinal toxin by an enzyme-linked immunosorbent assay (ELISA). The assay is specific for this type as it did not react with culture filtrates of otherClostridium species, including non-toxigenic 'E-like' organisms.
为了直接鉴定 E 型肉毒梭菌的产毒菌落,将可疑菌落均匀悬浮在含有 0.5%(w/v)明胶和 0.05%(w/v)吐温 20 的磷酸盐缓冲液中。离心后,通过酶联免疫吸附测定(ELISA)检测上清液中的肉毒毒素。该检测方法具有特异性,因为它不会与其他梭菌属的培养滤液发生反应,包括非产毒的“E 样”生物体。
