Even before the medical community had embraced the germ theory, two physicians had observed that the use of sloppy methods and contaminated instruments during surgery led to increased mortality of the surgical patient.
The best advantage of aseptic techniques is that harmful microbes are not introduced. For example in the surgical field or determining what microbe has caused what disease. An disadvantage is the cost of specialized clothing, materials, and sterilized instruments.
Aseptic.
It was Semmelweis who first introduces antiseptics to prevent disease. The first sterlization ( not complete) was given by Pasteur, known as pasteurization.
Semmelwise discovered childbirth fever. Semmelwise is known for his advocacy in handwashing.
He was the first physician to use disinfection in a hospital setting. He used "carbolic acid" solution to disinfect medical apparatus in the operating room and strict hand-washing techniques to ensure midwives did not transfer infection from one patient to another.

Isolation is the use of physical separation and strict aseptic technique for a patient who either has a contagious disease or is immunocompromised.
Louis Pasteur demonstrated that bacteria can cause diseases which made a big turn in society
Short answer is Koch's postulates. Long answer you can't ascribe any scientific data you may gather to a bunch of bacteria on a plate or in a culture, as you won't know which of the bacteria gave you the result you observed. So if you are trying to figure out which bacteria causes a disease, inoculating a mix of bacteria won't tell you which one causes the disease. Isolating each one using aseptic technique and then inoculating individually and finding the disease in one animal will tell you which bacteria caused to disease.
He is Edward Jenner . He demonstrated the first safe vaccination procedure to treat a smallpox disease. Btw. I'm Kazy Quijano Malazarte. visit me on facebook! :)) Dadzlil_me@yahoo.com
B. anthracis was the first bacterium conclusively demonstrated to cause disease, by Robert Koch in 1876
Semmelweis noticed that the death rates in mothers during pregnancy was unusually high. He noticed that the doctors in his hospital were going straight from examining diseased dead bodies in the morgue to delivering babies, and thought that perhaps this meant that they were transferring disease from the corpses to the mothers. He suggested that all doctors thoroughly wash their hands between patients, and almost immediately the death rate fell. This was the first time that the idea of infectious disease (passing disease via a pathogenic medium, i.e. bacteria and viruses) was considered. before this, contracting diseases was put down to chance.
