What are Antibiotics?
Antibiotics (from Greek means bĺos – life) are substances of biological origin, synthesized by microorganisms, which tend to both inhibit growth of pathogenic microorganisms, and completely destroy them.
100 years ago people died of diseases such as meningitis, pneumonia and many other infectious diseases. Their deaths were caused by absence of any antimicrobial agents. It turns out that antibiotics have saved people from extinction. Exactly with their help, it is managed to reduce mortality rate of patients with different infectious diseases in hundreds, and sometimes thousands of times.
Nowadays, it is created over 200 antimicrobial agents, among which more than 150 antibiotics are used for children’ treatment. Their intellectual names often confound people having no relation to medicine. How to understand sense in abundance of fancy terms? All antibiotics are divided into groups – depending on method of exposure to microorganisms:
- The first group – bactericidal antibiotics, they work on microbes, destroying them.
- The second group – bacteriostatic antibiotics, they inhibit bacteria growth.
