Superbug Resistance to Antimicrobial Nanosilver

A group of widely-occurring bacteria has been able to overcome the antimicrobial activity of nanosilver upon prolonged exposure.

We are and always have been at constant war against pathogens, not only in extreme situations such as epidemics but also on a daily basis. Along the way we have encountered a vast number of antimicrobial agents, each with unique target microorganisms and potency. These antimicrobials range from natural forms of disinfectant, such as moulds and plant extracts, to more sophisticated engineered chemicals including antiviral drugs.

Vets Versus Pets: Methicillin Resistance in Animals and Their Doctors

By Darren Trott, David Jordan, Mary Barton, Sam Abraham & Mitchell Groves

Humans and animals intimately sharing the same environment will inevitably be exposed to each other’s microbiota. When one of those organisms is a drug-resistant pathogen, disease prevention gets complex.

Staphylococcus aureus is responsible for a wide range of opportunistic infections in both humans and animals. In humans, infections with methicillin-resistant S. aureus (MRSA), which first appeared in the 1960s, have traditionally been acquired in hospital.

Resistance to Antibiotics

By Roy Robins Browne

Many of us take antibiotics for granted, but rising bacterial resistance is having major health consequences.

The World Health Organization has declared resistance to antibiotics to be one of the greatest threats to human health. This strong statement raises several questions.

  • What is antibiotic resistance, and why is it a threat to health?
  • Why does antibiotic resistance occur?
  • What can we do about it?

Life without antibiotics – the rise and rise of superbugs

By Matthew Cooper

Heralded as a “miracle of modern medicine” when they were first discovered, antibiotics have been overused for so long that most have become ineffective.

Stories about superbugs (bacteria resistant to antibiotics) now feature regularly in the news. This morning it’s about babies in a Melbourne hospital testing positive for a bacteria that antibiotics can’t beat.
