Microscopy Techniques in Bacterial Diagnosis
Microscopy remains the cornerstone of bacterial pathology. The Gram stain divides bacteria into Gram‑positive and Gram‑negative. This simple test guides therapy and classification.
The acid‑fast stain detects organisms like Mycobacterium tuberculosis. Its resistance to decolorization reveals critical pathogens.
The dark‑field microscopy highlights delicate organisms invisible under normal light. It is vital for diagnosing Treponema pallidum, the agent of syphilis.
Together, these methods provide rapid, reliable insights. They remain essential even in the age of molecular diagnostics.
