2. - A technique used to enhance the contrast of microorganisms under a microscope, important in Koch’s work to visualize bacteria.
3. - A disease caused by the bacterium Bacillus anthracis, which Koch was the first to link to a specific microorganism.
7. - The introduction of a pathogen or antigen into a body to stimulate the production of antibodies, a practice influenced by the understanding of diseases from Koch’s research.
9. Theory of Disease - The theory that specific diseases are caused by specific kinds of microorganisms, a concept Koch helped to solidify.
10. - An organism, such as a bacterium or virus, that causes disease.
12. - A microscopic organism, such as a bacterium, virus, or fungus, which was central to Koch’s research.
14. - The study of bacteria, a field in which Robert Koch made significant contributions.
15. - A serious infectious disease caused by the bacterium Mycobacterium tuberculosis, which Koch identified as the causative agent.

1. - The process of separating a specific organism from a mixed culture, a method Koch used to identify disease-causing bacteria.
4. - A substance that prevents the growth of disease-causing microorganisms, indirectly related to Koch's work on bacteria.
5. - The study of how diseases spread and can be controlled, a field influenced by Koch’s discoveries.
6. - A protein derived from Mycobacterium tuberculosis, developed by Koch as a diagnostic tool for tuberculosis.
8. - The process of growing bacteria in a controlled environment, which Koch used to isolate specific pathogens.
11. Postulates - A set of criteria established by Robert Koch to prove that a specific microorganism causes a specific disease.
13. - An instrument used for viewing very small objects, such as bacteria, that Koch utilized in his research.
