    Love affair with parasites


    From scabies to flesh-eating fire fish (okay we made that one up), Dr Deborah Holt knows, and loves, parasites. We find out why.

    Researchers discover a new silver species of Staphylococcus


    Scientists from a pioneering Northern Territory-based research project have uncovered two new species of staphylococcus. One of the two has been officially registered as Staphylococcus argenteus, or more commonly Silver Staph.

    Pain free golden staph treatment cleared for use in remote communities


    A northern Australian research team has provided reassuring support for the continued use of an oral treatment option for patients with skin infections, finding that there has been inaccurate reporting of resistance to the recommended antibiotic.
