Study Notes
Semmelweis's Contribution
- Semmelweis identified a critical link between sepsis in obstetric wards and preventing childbirth fever transmission.
- He implemented a handwashing policy using chloride of lime, calcium hypochlorite, and calcium chloride between patient interactions that significantly reduced mortality rates to about 2.4% (from 18%).
Pasteur's Work
- Pasteur's work focused on the observation that specific yeast strains performed the process of converting sugar into alcohol.
- This observation is linked to the process of "pasteurization".
Lister's Contribution
- Lister pioneered a method of reducing microorganisms on surgical wounds and incisions.
- He used bandages treated with carbolic acid (phenic acid) which killed microorganisms.
Identification of Microbial Pathogens
- Crucial discoveries identified the causative agents for various diseases including anthrax, tuberculosis, gonorrhea, and diphtheria.
- These advancements occurred in the latter half of the 19th century.
