Principle

1. Fixation    2. Staining with crystal violet    3. Treatment with iodine (forms a crystal violet-iodine complex)    4. Decolorization with 95% ethanol    5. Counterstaining with safranin or diluted fuchsin

CASE  3

Nasal Discharge Color- Mechanism: Neutrophil death → Myeloperoxidase → Yellow-green color- Viral progression: Color change normal in late stages (day 4-7)- Bacterial indicators:    - Duration >7 days or no improvement by day 10    - High fever with severe headache/facial pain- Initial improvement followed by worsening

Inspiration

It is divided into multiple grades from \"clear and transparent\" to \"immediately forms a white clot\

Formation Causes and Mechanisms

Creatine kinase isoenzyme (CK-MB)

- Gram-positive bacteria:    - Thick peptidoglycan layer    - Retains the crystal violet-iodine complex after decolorization → purple  - Gram-negative bacteria:    - Thin peptidoglycan layer + high lipid content in outer membrane    - Loses the complex during decolorization → takes up red counterstain → red

Steps

Changes during the typical meningitis stage

All indicators gradually return to normal.

Examination sequence

Observe the color of the cerebrospinal fluid

Gram staining classifies bacteria into Gram-positive (purple) and Gram-negative (red) based on differences in their cell wall structure and chemical composition.  - Developed by Hans Christian Gram in 1884.
