Staphylococcus epidermidis

Staphylococcus epidermidis is a species of bacteria that is part of the normal human flora. It is typically harmless, but can cause disease in immunocompromised individuals or in those with indwelling medical devices.

Overview

Staphylococcus epidermidis is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus. It is part of the normal human flora, typically found on the skin and mucous membranes. Although it is usually non-pathogenic, it can cause disease in immunocompromised individuals or in those with indwelling medical devices.

Pathogenesis

Staphylococcus epidermidis is capable of forming biofilms on plastic surfaces, such as those found in medical devices. This can lead to infection, particularly in individuals with weakened immune systems. The bacteria can also cause endocarditis, particularly in those with artificial heart valves.

Treatment

Treatment of Staphylococcus epidermidis infections typically involves the use of antibiotics. However, the bacteria is often resistant to many common antibiotics, making treatment difficult. In some cases, removal of the infected device may be necessary.

Prevention

Prevention of Staphylococcus epidermidis infections involves good hygiene practices, particularly in healthcare settings. This includes regular hand washing and sterilization of medical devices.
