An agent that fights against the growth of microorganisms is known as an antimicrobial. The use of these essential agents dates back to 2000 years ago. The application of antimicrobials found in plants seemed an excellent remedy for treating infections.

In the year 1928, the first natural antimicrobial fungus was discovered known as Penicilliumrubens. Penicillin was the name given to it in 1942.  Thus, the use of these agents in forming medicines to treat different infections is prevalent even today.

Antimicrobial medicines have classifications based on the microorganisms they fight. Antibiotics, for example, are known for their ability to resist different bacteria. Similarly, antifungals are effective in dealing with fungi. While antiseptic are those that are useful in preventing the spread of an infection or an illness. The functional classification is also another type of differentiation of antimicrobial agents. Examples of this differentiation include biostatic and microbicidal.

Due to the variety of uses of antimicrobial agents, their functions vary considerably. Here are some examples:

Antibacterial
They are known to be helpful in treating all kinds of respiratory tract infections. These drugs have significantly reduced the mortality rates that showed up as a result of prolonged bacterial infections left untreated. However, the same class of drugs is the most common when it comes to misuse as a viral infection shows no improvement when an antibacterial agent is used to treat it.

Antifungal
Treatment for problems such as ringworm, thrush, and athlete’s foot through the ability of these medicines to eliminate the presence of the fungal organism. While keeping the host undamaged, this substance does its job.

Antivirals
Used as a treatment method for illnesses caused by retroviruses, these drugs do not bring any harm to the host. There are many antiviral drugs found to be useful in the treatment of viruses such as HIV, Herpes, and Viral Hepatitis.
