What is methicillin-resistant Staph epidermidis?

A bacterial organism that is responsible for the difficult-to-treat infections in humans and responsible of hospital-acquired-infections. Methicillin-Resistant Staphylococcus epidermidis. Also called “Methicillin-Resistant Staphylococcus epidermidis”, inhabit typically on human epidermis (skin).

Why is Staphylococcus epidermidis resistant to methicillin?

However, the main mechanism of methicillin resistance in S. aureus is through the expression of a foreign PBP, PBP2a (not to be confused with PBP2), that is resistant to the action of methicillin but which can takeover the transpeptidation (cross-linking) reactions of the host PBPs.

What is the best antibiotic for Staphylococcus epidermidis?

Penicillin G, semisynthetic penicillinase-resistant penicillins, and cephalosporins are effective for the treatment of methicillin-sensitive Staph. epidermidis infections. Vancomycin is the drug of choice for infections caused by methicillin-resistant organisms.

Is Staph epidermidis a MSSA?

The staphylococcal infections that are resistant to penicillinase-resistant penicillins are termed MRSA (methicillin-resistant Staphylococcus aureus) or MRSE (methicillin-resistant Staphylococcus epidermidis).

What does a wound with MRSA look like?

Sometimes MRSA can cause an abscess or boil. This can start with a small bump that looks like a pimple or acne, but that quickly turns into a hard, painful red lump filled with pus or a cluster of pus-filled blisters.

Does epidermidis have capsules?

Many Staphylococcus epidermidis strains possess capsule or slime layers and consequently the staphylococcal cell surface should be regarded as a soft, polyelectrolyte layer allowing electrophoretic fluid flow through a layer of fixed charges.

Is MSSA a bacteremia?

MSSA Bacteremia occurs when the MSSA bacteria enter your bloodstream. This is a serious infection that has a high risk of complications and death. Once it’s in the bloodstream, the infection often spreads to other organs and tissues within the body such as the heart, lungs, or brain.

Is staph epidermidis contagious?

Staph infections are contagious through person-to-person contact. If an individual with staph has a wound that oozes, someone who comes into contact with this liquid can contract the infection.

What color is Staphylococcus epidermidis?

Cellular morphology and biochemistry S. epidermidis is a very hardy microorganism, consisting of nonmotile, Gram-positive cocci, arranged in grape-like clusters. It forms white, raised, cohesive colonies about 1–2 mm in diameter after overnight incubation, and is not hemolytic on blood agar.

What is MRSA and how dangerous is it?

MRSA is dangerous because it can penetrate the blood stream and can spread the bacteria easily and is because of the fact that people are unknowledgeable with regards to this. Prevention is better than cure. MRSA is incurable or hard to cure and fatal therefore, we have to really take good care of ourselves.

What diseases are caused by MRSA?

MRSA can cause many other symptoms, because once it gets into your bloodstream, MRSA can settle anywhere. It can cause abscess in your spleen, kidney, and spine. It can cause endocarditis (heart valve infections), osteomyelitis (bone infections), joint infections, breast mastitis, and prosthetic device infections.

What antibiotics is MRSA resistant to?

MRSA stands for methicillin-resistant Staphylococcus aureus, which is a type of Staphylococcus aureus that is resistant to the antibacterial activity of methicillin and other related antibiotics of the penicillin class.
