Sometimes, understanding the invisible means changing how we prevent its spread.
In October, Mad About Micro turns to Joseph Lister, the British surgeon whose pioneering work transformed approaches to infection control and laid the foundations for modern antiseptic practice.
Inspired by Louis Pasteur’s work on microorganisms, Lister recognised that microbes in the environment could contaminate wounds and cause infection. In the 1860s, he began introducing antiseptic techniques into surgical practice, including the use of carbolic acid to disinfect wounds, instruments and dressings.
The results helped demonstrate something revolutionary for the time: infection was not simply an unavoidable consequence of surgery. By controlling microbial contamination through effective antiseptic practices, the risk of infection could be significantly reduced.
Lister’s work helped establish principles that remain fundamental to infection control today: understanding where microbial risks exist, preventing contamination and using effective methods to control harmful microorganisms.
While the tools and technologies have advanced considerably, that principle remains unchanged. Whether in healthcare, laboratories, veterinary environments or food production, effective infection and contamination control depends on science that proves what works.
This month, we explore how Lister helped turn our understanding of microorganisms into practical prevention, and how the science of controlling microbes continues to protect people, animals, products and environments today.
This is where understanding microbes changed the standard of clean.
Follow the Mad About Micro series throughout 2026 as we explore the minds, methods and moments that continue to shape modern microbiology.
