The best way to directly observe spirochetes is ________ microscopy.

Question

Quizplus · Accepted Answer

Spirochetes are thin, coiled bacteria that are difficult to observe using traditional bright-field microscopy due to their small size and shape. Dark-field microscopy is the best way to observe spirochetes as it illuminates the specimen against a dark background, making them more visible. Fluorescent microscopy and electron scanning microscopy may also be used, but dark-field microscopy is the most common method for direct observation of spirochetes. Phase-contrast microscopy may also be used, but it is not as sensitive as dark-field microscopy for detecting thin, coiled structures like spirochetes.
