The fight against germs, Koch and bacteriology; aseptic surgery Flashcards
Who was Koch
A german doctor who was interested in Pasteur’s ideas
What did Koch do that was significant against anthrax
He proved scientifically that it was anthrax microorganisms causing anthrax.
What methods did Koch do to investigate Anthrax
Stained and photographed microorganisms.
What happened to Koch after he published his methods of investigating diseases?
He was invited to Berlin and was funded by the government
What was Pasteur doing after the finding of the Germ Theory
In 1878 he published his theory of infection linking infection to microorganisms
How did Pasteur’s assistant help find vaccinations
Pasteur’s team was experimenting on chicken cholera. Then his assistant went on holiday leaving a culture exposed. When he returned he injected that culture to the chickens. When there was no reaction they reinjected it was a fresh batch but nothing happened. Pasteur understood this and this helped pave a way to develop vaccinations on other vaccines.
How did Koch and Pasteurs work on vaccines combine
Pasteur in 1881 using his and Koch’s work publicly vaccinated cows and sheep against anthrax and they didn’t die.
What other vaccines did Pasteur develop after his work on chicken cholera
1885 he vaccinated a boy of rabies with his rabbit vaccine he had been working on
What did Koch do with his understanding after developing methods to study diseases with anthrax
He and his team in Berlin identified the microorganisms causing cholera in 1883 and tuberculosis in 1882. Also were the first to experiment with using agar jelly to grow cultures. Finally he started using chemical dyes to dye microorganisms to make it easier to study them under microscoeps
What was Pasteur and Koch’s relationship like?
They were rivals of some sort, as during the period of their investigations in vaccines Germany and France were at war. Both governments backed them with funding. Though they didn’t work together but they published them in scientific journals where they could build off each others work. Such as with the development of the anthrax vaccine.
What year did Koch find the microorganism causing blood poisoning
1878
What did Koch invent in 1878
A steam sterilizer to kill microorganisms for medical equipment. this was built off his rival Pasteur’s work on heat killing microorganisms
What effect did understanding of microorganisms increasing have on operation rooms
new techniques appeared and surgeons were attempting to prevent microorganisms getting anywhere near a open wound. Other than the sterilization of equipment and wound, surgeons wore clean clothes, put masks over their mouths, wore rubber gloves, and there were no longer any spectators
What was Lister experimenting with outside of antiseptic techniques
Around 1880 he was experimenting with options to solve the issue of blood loss as pain and infection were now solved. Previously open vessels were closed by either cauterization or tied close by ligatures but would become hard and could become a new source of infection. Then he found cat gut
What were some benefits of using catgut for blood loss
It was less likely to cause infection, could dissolve in the body after surgery, and others.
