  1. Classification of Bacteria

  2. Macroscopic Appearance • Color - pigment produced by bacteria

  3. Macroscopic Appearance • Texture - may be gloss, stringy, smooth, dull, dry & powdery, etc. Other: shape, size, elevation, odor, etc.

  4. Shape - Primary Classification • Cocci (coccus) = spherical

  5. Shape - Primary Classification • Bacilli (bacillus) = rod shaped

  6. Shape - Primary Classification • Sprilla (spirillum) = spiral shaped

  7. Arrangement • Diplo- = pairs of bacteria • Strepto- = chains of bacteria • Staphylo- = clusters of bacteria • Tetra = groups of four bacteria • Sarcinae = groups of eight bacteria

  9. Arrangement

  10. Response to Gram Stain • Determined by the biochemistry of the bacterial cell wall Gram+ bacteria = purple Gram- bacteria = reddish-pink *medically important test to identify bacteria

  11. Response to Gram Stain

  12. Other Methods of Classification • Nutrition • Oxygen requirements • Other unique features: pili, capsules, endospores, or flagella

  13. End
