Staph infections are caused by staphylococcus bacteria, types of germs commonly found on the skin or in the nose of even healthy individuals.
Most of the time, these bacteria cause no problems or result in relatively minor skin infections.
The symptoms of a staph infection depend on the type of infection: Skin infections can look like pimples or boils.
They may be red, swollen, and painful.
Sometimes there is pus or other drainage.
The antibiotic will vary depending on the type of infection.
In severe cases of staph infection, doctors use IV (intravenous) antibiotics to kill the bacteria.
