The big news in lupus research at the moment is the discovery that chronic Staphylococcus aureus infections can cause lupus, or a lupus-like autoimmune condition in mice.
Mayo Clinic researchers have been studying the link and the next step is to see if the same thing happens in humans as in mice - to see if the infections are cause, or exacerbate, lupus in people who are genetically prone to it.
The long-term hope of this research is to be able to prevent or reduce lupus flares.
