Questions and Answers
How did Pasteur discover the chicken cholera vaccine?
How did Pasteur discover the chicken cholera vaccine?
- Through a systematic process of elimination, testing various substances on chickens until he found one that prevented cholera infection.
- By observing that chickens exposed to an old, weakened culture of cholera microbes developed immunity, leading him to create a vaccine from this weakened culture. (correct)
- By genetically modifying cholera microbes to create a non-lethal strain that could be used as a vaccine.
- By intentionally exposing chickens to a virulent strain of cholera, observing their survival, and formulating a vaccine that mirrors this response.
What broader impact did Pasteur's understanding of microorganisms have on medical practices beyond vaccinations?
What broader impact did Pasteur's understanding of microorganisms have on medical practices beyond vaccinations?
- It had no real discernible impact, as infection was not a major worry at the time.
- It revolutionized basic hygiene practices and broadened their importance in preventing infections. (correct)
- It solely reinforced the importance of vaccination, without changing other aspects of healthcare.
- It led to the formalization of quarantine protocols, effectively sealing off infected people to prevent any spread of disease.
What was the significance of Pasteur's work to develop a vaccine for rabies?
What was the significance of Pasteur's work to develop a vaccine for rabies?
- It was significant in disproving the germ theory of disease, reinforcing older theories about disease causation.
- It marked the discovery of an effective treatment against a previously fatal and terrifying disease, demonstrating the power of vaccination. (correct)
- It was one in a series of trials that went nowhere, and did not lead to practical applications.
- It demonstrated the ineffectiveness of vaccines against viral infections, leading to the abandonment of vaccine research for viral diseases.

Study Notes
- Cholera microbes were studied in Pasteur's laboratory.
- Chickens became ill and died after inoculation with these microbes.
- In 1879, the microbe culture was abandoned for a month because Pasteur went on vacation.
- Birds inoculated with cholera microbes became ill but recovered.
- Birds inoculated with fresh cultures that had killed other birds survived.
- Pasteur realized that his chickens developed an immunity to cholera as a result of exposure to the weakened culture.
- He created a chicken cholera vaccine.
- Pasteur extended his studies to anthrax in cattle and sheep.
- Pasteur began work on a vaccine for rabies.
- In 1885, Pasteur injected his vaccine into Joseph Meister, a 9-year-old boy bitten by a rabid dog.
- Joseph Meister survived, and Pasteur became a national hero.
- Microorganisms cause disease and can spread through the air or by direct contact.
- Vaccination regimes and basic hygiene practices are crucial to preventing infection.
- Pasteur gave Meister 13 vaccine injections over 10 days, and Meister recovered.
- Pasteur devised methods to protect humanity from two deadly diseases: Anthrax and Rabies.
