Join the fight against antibiotic resistance

The development of antibiotics was one of the most important advances of medicine. Now, because of the overuse and misuse of antibiotics, bacterial infections that were once easily cured with antibiotics are becoming harder to treat.

This is due to antibiotic resistance. It has been identified by the WHO as one of the greatest threats to human health today.

For health professionals  

Prescribing a routine course of antibiotics significantly increases the likelihood of an individual carrying a resistant bacterial strain – resistant bacteria can be spread to family, friends and the broader community. To minimise antibiotic resistance, Australian guidelines recommend that an antibiotic should only be prescribed:

  • when benefits to the patient are likely to be substantial
  • with the narrowest spectrum to treat the likely pathogen
  • at the appropriate dose and for the appropriate duration.

Staphylococcus aureus that is methicillin-resistant (MRSA), and therefore resistant to all β-lactam antibiotics, is widespread, with skin and soft tissue infections among the most common sources. Although most of the data describe the problem in hospital settings, there is an emerging picture of antibiotic resistance in community settings across Australia.
