The best way to directly observe spirochetes is through _____ microscopy.

Question

Quizplus · Accepted Answer

Spirochetes are thin, spiral-shaped bacteria with a unique motility pattern. They are difficult to visualize using bright-field, fluorescent, or phase-contrast microscopy due to their thinness and low contrast. Dark-field microscopy is the best way to directly observe spirochetes, as it uses oblique illumination to create a bright background against which the spiral shape of the bacteria can be visualized. Electron scanning microscopy is also useful for high-resolution imaging but is not typically used for routine diagnostic purposes.
