Study Notes
Milestones in Microbiology
- Ernst Ruska is the founder of the electron microscope.
- Lady Mary Wortley Montagu introduced variolation for immunizing against smallpox.
- Alexander Fleming discovered the most commonly used antibiotic substance of the last century, penicillin.
- The additional fifth criterion introduced subsequently to Koch's postulates is the requirement for the microbial isolate to recreate the disease in an animal model.
- It is challenging to apply Koch's postulates to study all human diseases because many diseases cannot be replicated in an animal model.
- The basis of molecular Koch's postulates introduced by Stanley Falkow is the identification of a specific gene or protein that is responsible for the pathogenesis of the disease.
- Paul Ehrlich is known as the father of chemotherapy.
- Paul Ehrlich proposed the side chain theory for antibody production, suggesting that antibodies are produced by the immune system as a response to the presence of foreign substances.
- The 'Gram stain' was developed to differentiate between different types of bacteria based on the composition of their cell walls.
- Paul Ehrlich discovered Salvarsan as the first effective medicinal treatment for syphilis.
