Study Notes
Microscopy Techniques
- Electron microscope and fluorescent microscope are used to visualize viruses.
- Electron microscope uses ultraviolet rays as a light source.
- Fluorescent microscope utilizes certain dyes like Chain & pairs.
Gram Staining
- Gram staining differentiates bacteria based on their cell wall structure.
- Peptidoglycan thickness of the cell wall determines the outcome of the staining.
- Gram-negative cocci include Neisseria, Haemophilus, and Bordetella.
- 95% ethyl alcohol acts as the decolorizing agent in the staining process.
Bacterial Morphologies
- Gram-positive bacilli include Corynebacteria, Bacillus, and Clostridium.
- Spirochete and spirillum are two other bacterial morphologies.
Viral Load Measurement
- RNA or DNA identification and quantification determines the viral load.
