Antibiotics & Antibiotic resistance



- Antibiotics are powerful drugs, but they are not the cure for all that ails you. Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria

- Antibiotic resistance is a   form of drug resistance whereby some (or, less commonly, all) sub-populations of a microorganisms , usually a bacterial species, are able to survive exposure to one or more antibiotics.

- Overuse of broad-spectrum antibiotics, such as second- and third-generation cephalosporins, greatly hastens the development of methicillin resistance.


- Other factors contributing towards resistance include incorrect diagnosis, unnecessary prescriptions, improper use of antibiotics by patients, and the use of antibiotics as livestock food additives for growth promotion.

- NEVER take an antibiotic to treat a viral infection, such as the flu or common cold. An antibiotic can only treat infections that are bacterial, not viral.
