Antimicrobials
Antimicrobials
Antimicrobials (pronounced: an-ti-mi-kro-bee-uhls) are a group of substances that kill or inhibit the growth of microorganisms. The term is derived from the Greek words 'anti' meaning 'against', 'micro' meaning 'small', and 'bios' meaning 'life'.
Types of Antimicrobials
Antimicrobials can be classified into several types based on the microorganisms they act against. These include:
- Antibiotics: These are antimicrobials derived from natural sources and are used against bacteria.
- Antivirals: These are used to treat viral infections.
- Antifungals: These are used to treat fungal infections.
- Antiparasitics: These are used to treat parasitic infections.
Mechanism of Action
Antimicrobials work by interfering with the life processes of microorganisms, thereby killing them or inhibiting their growth. The mechanisms of action vary depending on the type of antimicrobial. For example, antibiotics often work by disrupting the cell wall of bacteria, while antivirals inhibit the replication of viruses.
Resistance to Antimicrobials
A major concern in the use of antimicrobials is the development of antimicrobial resistance. This occurs when microorganisms evolve mechanisms to withstand the effects of antimicrobials, making them less effective.
