Infectious Diseases and Antibiotics
Antibiotics are medicines used to treat infections or diseases caused by bacteria .Antibiotics are used for a range of infections caused by bacteria, including urinary tract infections, skin infections and infected wounds. Antibiotics which affect a wide range of bacteria are called broad spectrum antibiotics (e.g. amoxicillin and gentamicin) and antibiotics that affect only a few types of bacteria are called narrow spectrum antibiotics (e.g. penicillin). Antibiotics mode of action is by blocking vital processes in bacteria, killing the bacteria, or stopping them from multiplying. This helps the body's natural immune system to fight the bacterial infection.
