Staphylococcus infection, also known as staph infection, is a type of bacterial infection caused by Staphylococcus bacteria. The infection can range from mild to severe and can affect various parts of the body, including the skin, respiratory tract, and bloodstream. There are several synonyms for staphylococcus infection, including staphylococcal disease, staphylococcal infection, staphylococcus aureus infection, and MRSA infection (Methicillin-resistant Staphylococcus aureus). Other related terms include septicemia, cellulitis, and impetigo. Staph infections are commonly treated with antibiotics, but some strains of bacteria have become resistant to traditional treatments. Practicing good hygiene habits, such as washing your hands regularly, can help reduce the risk of contracting a staph infection.
