    those bacteria that ferment lactose
  2. Gram pos rods
    • Bacillus & Clostridium species
    • Categorize as to:
    • Aerobic or anaerobic
    • Sporeformers
    • Catalase reaction
    • Starch hydrolysis reaction
  3. Bacillus
    • Gram Pos rods
    • Single, facultative aerobes
    • sporeformers
    • Most are motile
    • Catalase +
    • Hydrolyzes starch (pos)
  4. Clostridium
    • Gram Pos rods
    • Anaerobic
    • spore formers
    • most not motile

    • Non-motile Eukaryotes:
    • Unicellular yeast cells
    • reproduce by budding

    • Penicillium notatum, Aspergillus niger
  21. Penicillium vs aspergillus: how they look
    • Aspergillus looks like cauliflower 
    • Penicillin looks like cadavar hands
  22. Protozoa

    • Trophozoite form: motile, reproduce, cause disease
    • Cyst form - Non motile, resting (dormant, non reproducing) resistant. gets into body first as cyst, then transforms into tropazoile
  25. Amoebas (sarcodia)
    • move by pseudopods
    • includes:
    • entamoeba histolytica (causes amoebic dysentery)
