The Henry oblique transmitted-light viewing technique was modified to provide a more precise, convenient, and familiar manner with which to read (score) and recognize colonies of listeriae by their distinct bluish cast. The simplified technique involved illuminating each colony directly with a high-intensity lamp while viewing it with a hand lens at a precise angle in place of a scanning light microscope.
亨利斜射透光观察技术经过改进,以提供一种更精确、便捷且为人熟悉的方式,通过李斯特菌菌落独特的蓝灰色调对其进行读取(评分)和识别。简化后的技术是用高强度灯直接照射每个菌落,同时用手持放大镜以精确角度进行观察,取代扫描光学显微镜。
