Antibiotic Resistance

Some bacteria can evolve mechanisms that make them resistant to the effects of antibiotics, rendering treatments less effective or ineffective.

Causes of Antibiotic Resistance

Includes overuse or misuse of antibiotics, over-prescription by doctors, and inappropriate use in agriculture.

MRSA

Methicillin-resistant Staphylococcus aureus, a well-known example of antibiotic-resistant bacteria.

Antibiotics vs Viruses

Antibiotics kill bacteria but have no effect on viruses, which require antiviral drugs for treatment.

Responsible Use of Antibiotics

Antibiotics should only be prescribed when necessary to limit the development of resistant bacteria.

Effectiveness of Antibiotics

Antibiotics target specific components of bacterial cells, making them effective against bacterial infections.

Treatment for Viral Infections

Viral infections are typically treated with antiviral drugs that work differently than antibiotics.

Essential Use of Antibiotics

Using antibiotics only when necessary reduces the opportunity for bacteria to adapt and evolve resistance mechanisms.

Example of Resistance Development

MRSA developed resistance to methicillin due to misuse and overuse of antibiotics.
