Staphylococcus is a genus of bacteria that can cause a wide range of infections in humans. These infections can range from minor skin infections, such as boils and impetigo, to more serious infections, such as sepsis, pneumonia, and endocarditis.
Staphylococcus bacteria are commonly found on the skin and in the nasal passages of healthy individuals. However, when the skin is broken or the immune system is compromised, these bacteria can enter the body and cause infection. Staphylococcus infections are often spread through contact with infected individuals or contaminated surfaces.
Symptoms of a staphylococcal infection can vary depending on the type of infection and the individual affected. Minor skin infections typically present as red, swollen areas of skin that may be tender to the touch. More serious infections, such as sepsis, can cause fever, chills, and low blood pressure.
Treatment for staphylococcal infections typically involves antibiotics, such as methicillin, vancomycin, or linezolid, depending on the antibiotic resistance profile of the infecting strain. In some cases, drainage or surgical removal of infected tissue may also be necessary.
Prevention of staphylococcal infections involves practicing good hygiene, such as washing hands frequently and avoiding close contact with infected individuals or contaminated surfaces. Individuals who are at higher risk for staphylococcal infections, such as those with weakened immune systems or who are hospitalized, may also be given prophylactic antibiotics to prevent infection.
