Response B       Score:_____

   I will describe how the resistance of bacteria to antibiotics. First, it’s big problem in the hospitals. Hospitals used antibiotics in 1950, but resistance appearing a problem. The reason is danger of hospital infection is very bad so people had better stay home a hospital.

   Second, penicillin was a wonder drug in 1940. You gave a man in hospital 10000 penicillin and he cured the disease. But today you give 24 penicillin but he might die. The reason is bacteria smart so very difficult treat pneumonia and other disease in a hospital. Several people die – because the reason is the resistance of the bacteria to antibiotics.

   Third, how does this happen is you dose a colony of bacteria with an antibiotic. The colony killed except a few cells. This is a dangerous problem in a hospital because people may die. Doctors think tuberculosis was a defeated disease but the increase is by 20%.

   The changes the view of antibiotics as ‘wonder drugs’ by resistance of bacteria to antibiotics. It’s a big problem today and doctors can’t find drugs to cure the disease such as tuberculoses. Penicillin and other antibiotic drugs were wonder drugs in 1940-so it’s necessary to have a different view of antibiotics today.
