A staphylococcal infection or staph infection is an infection caused by members of the Staphylococcus genus of bacteria.Once the bacterium has been identified as the cause of the illness, treatment is often in the form of antibiotics and, drainage of the infected area.However, many strains of this bacterium have become antibiotic resistant; for those suffering these kinds of infection, the body's own immune system is the only defense against the disease.[1]

Signs and symptoms

Staph infection is normally characterized by redness, pus, swelling, and tenderness in the areas infected, though each type of skin infection caused by staph bacteria is different.[2]


Staph infection can occur due to open wounds, weakened immune system, proximity to an infected individual and post surgical infection.[3][4]


In terms of the diagnosis of Staph infection, one finds that a physical exam, culture (via nasal, stool, or tissue sample) and imaging tests are done.[2]


Staph infection classification is divided into coagulase positive (Staphylococcus aureus) and coagulase negative (S. epidermidis).[5][6]


Treatment for staph infection varies depending on the type and severity of infection, common treatments are antibiotics, topical creams, and drainage/cleaning of infectious wounds.[7][8]


Staphylococcus bacteria is one of the leading community-acquired bacteria and a cause for concern among healthcare professionals, especially new antibiotic-resistant strains.[9][10]
