Debate over spontaneous generation
evidence-proscons.

• Francesco Redi Maggots appeared only if flies
  were allowed to leave their eggs on the meat.
• John Needham Claimed that the microbes developed
  spontaneously from the fluids.
• Lazzaro Spallanzani Showed that nutrient fluids
  heated after being sealed in a flask did not grow.

  by Bacillus brevis, from soil.

13
Modern Developments in Micro.

• Recombinant DNA Technology.
• Immunology Rebecca Lancefield proposed a
  classification system based on certain components
  in the cellwalls of the bacteria.
• Virology Dmitri Iwanowski reported that the TMV
  was small enough to pass through bacterial
  filters.
