Staph infections can cause many types of infections. Most commonly, staph infections cause skin and soft tissue infections, such as boils, impetigo or cellulitis. Less commonly, staph infections cause internal infections of the blood, heart valves, heart implants, such as pacemakers and catheters, spleen, bones and joints. Staph bacteria can also cause pneumonia, meningitis, urinary tract infections (especially in people with a urinary catheter) and food poisoning. ::: body-ad-mobile zones:: 232632,232343,227373,232642 types:: 5 disclaimer:: ADVERTISEMENT typeFilter:: display adCount:: 1 :::
