In the body, specific white blood cells called neutrophils throw nets loaded with antibacterial compounds on invading bacteria in order to kill them. This process is called NETosis, and is especially effective on the pathogen staphylococcus aureus.
However, people with lupus, an auto-immune disease, are more prone to getting staph, because their neutrophils do not net properly due to an abundance of calprotectin, (dark purple spots) resulting in increased susceptibility to the pathogen, which occurs in yellow clusters. Lupus commonly affects women, particularly women of color, however the disease is very hard to diagnose, so outwardly there are no differences between a carrier and a non-carrier on the street.
