Explanation:
Before Joseph Lister was inspired by Pasteur's germ theory to perform sterile operations, doctors harmed more patients with infections than they helped with surgery.
This was because doctors didn't do enough to prevent the spread of bacteria through surgical equipment and in the end they ended up causing more problems for their patients than the help they gave.
