Staphylococcus is a bacteria class that look like a bunch of grapes when looked at under a microscope. It belongs to the family Micrococcaceae of the order Eubacteriales. That information will help you research the many types of Staph on the internet. Staph, for short(also seen as the letter "S"), have many species. Some produce toxins outside the body (exotoxins) that are destructive to the body tissues, and some cause toxins inside the body (endotoxins) and are the cause of a common type of food poisoning. Usually Staph is treated with antibiotics, but there are strains of Staph that are resistant to antibiotics. When you bathe with antibacterial soaps, all bacteria are killed, the good and the bad. When you use it long enough, bacteria become "immune" to the effect and it isn't useful anymore. You can have your doctor take a sample of fluid from the boil to have the type of Staph identified and tested for antibiotics that will be effective against the type your husband has.
