Staphylococcal epidermis all are true EXCEPT: (A) Sensitive to penicillin, (B) Makes slimy layer, (C) Coagulase negative, (D) Coagulase Positive
Answer is D. (D) Coagulase Positive # Staphylococcus epidermidis is a coagulase negative species of staphylococcus.> Staphylococcus epidermidis is invariably present on normal human skin.> It is nonpathogenic ordinarily but can cause disease when the host defences are breached. It is a common cause of stitch abscesses.> It has a predilection for growth on implanted foreign bodies such as artificial heart valves, shunts, intravascular catheters and prosthetic appliances, leading to bacteremia.> Hospital strains of Staphylococcus epidermidis are usually multiple drug resistant.> Endocarditis may be caused,particularly in drug addicts.
