The Project ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Morphology of and types of TB bacilli Mycobacterium Tuberculosis (2–4μm x 0.3–0.5μm) Mycobacterium bovis (1.5–1.9μm) Mycobacterium avium (1.0–1.8μm x 0.5μm) Mycobact. kansasii ( usually 4–5μm x 0.3μm)

Test Example: ZN stained slide (sputum smear at 40x magnification after image processing)

Test Example: Auramine stained slide (sputum smear at 6 3 0 x magnification after image processing) EDGE DETECTION

Results --- specificity for a single bacillus Auramine stain ZN stain
