Why do rates of antimicrobial resistant UTI differ across the world?

It’s well known that rates of antibiotic resistance differ between countries and that previous exposure to antibiotics increases resistance. A recent study in the BMJ looked at rates of resistance in paediatric UTI’s across the globe.

Meningitis: An unexpected adverse effect of antibiotics

Another recent case-control study examining the effects of antimicrobial prescribing on the microbiome and how it affects human health has recently been published. This study aimed to determine if antibiotic prescriptions in the previous year resulted in an increased risk of meningitis.

Antibiotic Resistance: Facts and Figures

While we spend a lot of time talking about reducing antibiotic resistance it can difficult to get a feel for the size of the problem. The team at BioMerieux have put together some facts and figures that help quantify the problem.

What does Gram negative rod resistance mean for us clinically?

Enterobacteriacae (gram negative rods) include E. coli, Salmonella and Klebsiella sp. which are important human pathogens. Resistance of the Enterobacteriacae to antibiotics, particularly beta-lactams, is a growing clinical problem. Over use of antibiotics has changed the natural evolution of bacteria creating mobile genes that rapidly spread resistance through populations. Even in countries with controlled antibiotic use have […]

Some antimicrobial stewardship success stories

The NPSMedicinewise 2014-2015 Annual Report was released this week listing the achievements the organisation has made in improving the health of Australians. NPSMedicinewise is active in the fight against antimicrobial resistance and have successfully improved the use of antimicrobials in Australia over this time period.

What is the best way to treat skin abscess?

Skin (staphylococcal) abscesses (boils) are often treated with antimicrobials, but are they really needed?
