   In hospital rooms of the 1800s, many people died from infections that started in uncovered, or open, wounds. A Scottish doctor named Joseph Lister guessed that germs might be causing these infections. He looked for and found a good “germ killer.” It was carbolic acid. Lister began to cover open wounds with bandages soaked in weak carbolic acid. Lister also washed his instruments and his hands with carbolic acid. He even tried spraying his operating room with carbolic acid.

   1. What did Doctor Lister begin to do to help prevent infections?

   
   

   
   

   
   

   
   

   2. What did Doctor Lister also do to try and prevent infections?

   
   

   
   

   
   

   3. What did Doctor Lister try spraying his operating room with to help prevent infections?

Lister began to cover open wounds with bandages soaked in weak carbolic acid. Lister also washed his instruments and his hands with carbolic acid. He even tried spraying his operating room with carbolic acid. The results were great. The number of infections went down. Many patients stayed alive who would have died before. Lister’s carbolic acid was the first antiseptic, or germ killer, that worked. Soon, doctors learned that steam could kill germs, too. Today, medical instruments and bandages are sterilized by putting them in hot steam. Doctors wear sterilized gloves, clothes, and masks.

   1. What Lister use that was the first of its kind to work?

   
   

   
   

   
   

   2. What did doctors later learn that could also killer germs?

   
   

   
   

   
   

   3. What is done today and what do doctors wear to prevent infections?

Today, medical instruments and bandages are sterilized by putting them in hot steam. Doctors wear sterilized gloves, clothes, and masks. Several years after Lister’s discovery of antiseptics, two other scientists found out more about fighting disease. They were Louis Pasteur and Robert Koch. Together these scientists came up with the idea of the germ theory. The theory proposed that germs, or microscopic organisms, caused diseases. Their theory, led to many other advancements in understanding the causes of diseases.

   1. Explain what doctors later discovered, and what is done today to prevent infections.

   
   

   
   

   
   

   2. Explain what happened several years after Lister’s discovery and who were they.

   
   

   
   

   
   

   3. Explain what the “germ theory” proposed and what this theory led to.
