Antibiotics commonly block biochemical pathways important for the growth of Bacteria.
Antibiotics commonly block biochemical pathways important for bacteria. But virus do not use these pathways at all, and that is the reason why antibiotics do not work against viral infections. In example, Penicillin blocks the formation of cell wall in bacteria.Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.
- Only bacterial infections can be killed with antibiotics.
- The common cold, flu, most coughs, some bronchitis infections, most sore throats, and the stomach flu are all caused by viruses. Antibiotics won’t work to treat them.
