Who are the two scientists credited with developing methods to prevent infections through antiseptic practices?

• A. Edward Jenner and Louis Pasteur
• B. Louis Pasteur and Joseph Lister
• C. Salk and Sabin
• D. Roentgen and Crick

Answer: (B)

Antiseptic practices to prevent infections hinge on the idea that microorganisms cause disease and that contamination can be controlled. Joseph Lister pioneered antiseptic technique in surgery by using carbolic acid to clean wounds, instruments, and dressings, which dramatically cut infection rates after operations. Louis Pasteur provided the scientific foundation with germ theory, showing that microbes are responsible for disease and that preventing their spread through proper sanitation and sterilization is possible. Put together, their work established how infections can be prevented through antiseptic methods in medical care. The other options refer to vaccines or unrelated discoveries: Jenner developed the smallpox vaccine, Salk and Sabin worked on polio vaccines, and Roentgen and Crick are known for X-rays and the structure of DNA, not antiseptic practices.
