Introduction to Koch and 19th Century Medicine

Koch's Contributions: Robert Koch was a pioneering German scientist who made significant advances in microbiology during the 19th century. He developed techniques to identify specific bacteria that caused diseases, such as tuberculosis and cholera.

Vocabulary:

  • Bacterium: a single-celled organism that can cause disease.
  • Petri dish: a shallow dish used to culture bacteria.
  • Aseptic technique: methods to prevent contamination of cultures.
  • Koch's Postulates: a set of criteria to establish a causative relationship between a microbe and a disease.

Source A: Excerpt from Koch's own writings

'By isolating bacteria and growing them in pure cultures, we can prove which microbes cause specific diseases.' Provenance: Koch's 1884 publication on his methods.
