Antibiotic Resistance (cont.)


Antimicrobial is a general term given to substances including medicines that kill or slow the growth of microbes.

Microbe is a collective name given to bacteria (e.g., Staphylococcus aureus, which causes some staph infections), viruses (e.g., influenza, which causes the flu), fungi (e.g., Candida albicans, which causes some yeast infections), and parasites (e.g., Plasmodium falciparum, which causes malaria)

Examples of antimicrobial agents:

  • Tetracycline (one antibiotic used to treat urinary tract infections )
  • Oseltamivir or Tamiflu® (antiviral that treats the flu)
  • Terbinafine or Lamisil® (antifungal that treats athlete's foot)


An antibiotic is a medicine designed to kill or slow the growth of bacteria and some fungi. Antibiotics are commonly used to fight bacterial infections, but cannot fight against infections caused by viruses.

Example of an antibiotic:

  • Azithromycin or Zithromax (Z-Pak)®
  • Vancomycin is the last line of defense for certain methicillin-resistant Staphylococcus aureus (MRSA) infections.
