Fluorescence microscopy
Study Notes
- Microscopes used in clinical practice are light microscopes.
- Compound light microscopes are the most common in microbiology.
- Electron microscopes provide higher magnification for observing small microorganisms.
- Brightfield microscopy is commonly used with stained preparations.
- Darkfield microscopy is used for observing bacteria such as treponemes and leptospires.
- Phase-contrast microscopy allows examination of live unstained organisms.
- Fluorescence microscopy uses fluorochromes to stain specimens.
- Excited molecules emit light of different wavelengths in fluorescence microscopy.
- Auramine differential staining is an application of fluorescence microscopy.
- Rapid diagnostic kits use fluorescent antibodies for identifying many pathogens.
