   In general, the lecture contradicts the idea that antibiotics are “wonder drugs” as the reading states. On the contrary, antibiotics are not wonder drugs because the resistance of bacteria to antibiotics.

   According to the reading, the discovery of penicillin and other antibiotic drugs saved many lives that were threatened by dangerous diseases such a pneumonia and tuberculosis. In the twentieth century, penicillin was first a wonder drug because it can cure streptococcus infections. Furthermore, streptomycin found to be potent against tuberculosis. However, the lecture made the point that this is not true in the present. Today tuberculosis is a major illness again because the new strain of bacteria is resistant to antibiotics.

   According to the lecture, bacteria have developed effective weapons against some drugs, for example, penicillin. They evolve to counteract antibiotics. It happens when a few cells of bacteria survive because they have the resistance gene. Then new strains of bacteria appeared. After that, antibiotics may attack but they do not kill all disease infections. This serious problem today is the resistance of bacteria to antibiotics.

   In the past, antibiotic drugs could attack and kill diseases, but this is not true today. Therefore, it is necessary to develop new wonder drugs to fight disease.
