'against'[1] and σηπτικός, sēptikos, 'putrefactive'[2]) is an antimicrobial substance or compound that is applied to living tissue to reduce the possibility of sepsis, infection, or putrefaction.Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection).Ignaz Semmelweis showed already in 1847-1848 that hand washing prior to delivery reduced puerperal fever.[5] Despite this, many hospitals continued to practice surgery in unsanitary conditions, with some surgeons taking pride in their bloodstained operating gowns.In 1867 Joseph Lister published seminal paper Antiseptic Principle of the Practice of Surgery, where he explained this reduction in terms of Louis Pasteur's germ theory.
