are there different types of mrsa?

There are two types of MRSA infections: community-acquired (CA) and hospital-acquired (HA). The most common type is HA-MRSA, but CA-MRSA is becoming more common.
78326
The most common species detected were Staphylococcus epidermidis, Staphylococcus hominis, and Staphylococcus haemolyticus. These three species accounted for nearly 98% of the clinically significant isolates and 89% of the contaminants. The isolation of other species almost always represented contamination.

The use of different types of antibiotics over the years has led to the emergence of multi-resistant MRSA strains2, the result of mutations in genes coding for target proteins and through the acquisition and accumulation of antibiotic resistance-conferring genes.

Methicillin-resistant Staphylococcus aureus (MRSA) can survive on some surfaces, like towels, razors, furniture, and athletic equipment for hours, days, or even weeks. It can spread to people who touch a contaminated surface, and MRSA can cause infections if it gets into a cut, scrape, or open wound.

Some impetigo is caused by a type of bacteria called methicillin-resistant Staphylococcus aureus (MRSA). This type of bacteria is hard to kill. This type of impetigo can be difficult to treat.

Bloodstream infection If MRSA bacteria enter into the bloodstream from your skin, they can affect almost any part of the body. They can cause: septic shock (widespread infection of the blood that leads to a fall in blood pressure and organ failure) severe joint problems (septic arthritis)

MRSA bacteria are usually spread through skin-to-skin contact with someone who has an MRSA infection or who is colonised by the bacteria. C. difficile spores leave the body in an infected person's diarrhoea. The spores can then contaminate their surroundings, such as toilets, bedclothes, skin and clothing.

It's possible for a mother to pass MRSA to her baby during a normal delivery (vaginal birth). MRSA can also be passed on from other babies in the hospital if they're carrying it. If a baby develops an MRSA infection, it can be treated. Serious infections in babies caused by MRSA are rare.

Resistant bacteria are called methicillin-resistant Staphylococcus aureus, or MRSA. 2. The bacteria that can be treated by methicillin class antibiotics are MSSA.

If MRSA infections keep coming back again and again, your health care provider can help you sort out the reasons you keep getting them. Even if active infections go away, you can still have MRSA bacteria on your skin and in your nose. This means you are now a carrier of MRSA.

Methicillin-resistant Staphylococcus aureus (MRSA) infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections.

MRSA infections are not common in dogs and cats. While MRSA is a major issue in human health, dogs are more likely to be affected by a different bacterial strain called methicillin-resistant Staphylococcus pseudintermedius or MRSP. These infections usually infect dogs through skin wounds, surgical sites and ears.

MRSA is treatable. By definition, MRSA is resistant to some antibiotics. But other kinds of antibiotics still work. If you have a severe infection, or MRSA in the bloodstream, you will need intravenous antibiotics.

Cellulitis, when untreated, may rarely spread to the deeper tissues and cause serious fasciitis. Staph (Staphylococcus aureus), including methicillin-resistant strains (MRSA), is another common type of bacteria that causes cellulitis.

Staphylococcal Infections. Staphylococci are gram-positive aerobic organisms. Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia, endocarditis, and osteomyelitis.

MRSA Infections Can Be Flesh Eaters. Oct. 12, 2006 -- Drug-resistant staph infections (MRSA infections) are on the rise and may, in rare cases, cause a potentially deadly flesh-eating disease called necrotizing fasciitis.
