Describe the following illustrations.

• Describe the following illustrations.
• Do you know the man in the picture?
• Can you predict the theme of the topic?

Read and guess the meanings of following word combinations:

development of particular microbe certain conditions to be attenuated pathogenic activity

become a vaccine theory of microbes on the surface of the object to be heated to a temperature of…. principles of asepsis

Read the text and find the sentences with Pasteur’s theory.

• Asepsis
• If all the works carried out by the great French researches Pasteur were divided into three groups, they would form three great discoveries.
• The first one might be formulated thus: “Each fermentation is produced by the development of a particular microbe”.
• The second one might be given this formula: “Each infection disease is produced by the development of a particular microbe within the human organism”.
• The third one might be the following: “The microbe of an infectious disease, under certain conditions, is attenuated in its pathogenic activity; from a microbe it becomes a vaccine.”

In 1878 while delivering his lecture on the theory of a microbes at the Academy of Sciences in Paris Pasteur said that if he were a surgeon, who knew of the dangers produced by microbes existing on the surface of every object, particularly in hospitals, not only should he use clean instruments, but after washing his hands with the greatest care, he would employ only those bandages and charpie which had been heated to a temperature of 130 to 150 C.

• In 1878 while delivering his lecture on the theory of a microbes at the Academy of Sciences in Paris Pasteur said that if he were a surgeon, who knew of the dangers produced by microbes existing on the surface of every object, particularly in hospitals, not only should he use clean instruments, but after washing his hands with the greatest care, he would employ only those bandages and charpie which had been heated to a temperature of 130 to 150 C.
• If he employed the water he would heat, it to a temperature of 110 to 120 C, since observation had shown the clearest water to contain still greater number of microbes.
• Had those principles of asepsis, on which Pasteur insisted, not been strictly followed in medicine thousands and thousands of human lives would have been lost because of sepsis.

Answer the questions:

• Where was Pasteur from?
• How many groups of his discoveries can
• you name?
• How is formulated his first discovery?
• What about other discoveries?
• What did he say about bandages, charpie, instruments?
• What would have happened if the main principles of asepsis had not been followed?

Do the activity “true”or “false”:

• The first one theory of Pasteur is about fermentation that is produced by the development of a particular microbe.
• The microbe of an infectious disease, under certain conditions, is attenuated in its pathogenic activity; from a vaccine it becomes a microbe.
• In 1878 Louis Pasteur delivered the lecture on the Theory of microbes at the Academy of Sciences in London.

If he were a surgeon, he would employ only those bandages and charpie which had been heated to a temperature of 130 to 150 C.

Do you know other scientists who had a contribution in the development of Asepsis?

• Write a short report about one of them.
