Vancomycin and Teicoplanin are used to treat MRSA infections.
Because the oral absorption of vancomycin and Teicoplanin is very low, these agents must be administered intravenously to control systemic infections.
Some CA-MRSA strains are susceptible to trimethoprim-sulfamethoxazole , doxycycline and clindamycin.
Both CA-MRSA and HA-MRSA are resistant to traditional anti-staphylococcal beta-lactam antibiotics.
MRSA infections are transmitted from person to person by direct contact with the skin, clothing, or area that had recent physical contact with a MRSA-infected person.
MRSA can begin an infection of the skin, a wound (often a surgical site), or a location where medical devices are placed (catheters, IV lines, or other devices).
Cellulitis, abscess, or draining pus is often one of the first signs and symptoms of MRSA infections.
It’s important to finish all doses – even if your symptoms fade. Stopping early can cause the infection to come back – and can allow the MRSA bacteria to develop resistance against the few antibiotics that still work.

Attention to personal hygiene is key to avoiding MRSA infections.

Wash your hands frequently, especially if visiting someone in a hospital
Make sure all doctors, nurses, and other health care providers wash their hands before examining you
Do not share personal items with another person
Cover all wounds with a clean bandage, and avoid contact with other people’s soiled bandages
Avoid common whirlpools or saunas if another participant has an open sore
Make sure that shared bathing facilities are clean

What is mrsa ?
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that is highly resistant to some antibiotics.
MRSA is a strain of Staphylococcus aureus (S. aureus) bacteria.
Staphylococcus aureus is a common type of bacteria that normally live on the skin and sometimes in the nasal passages of healthy people.

CA-MRSA Community-acquired MRSA
HA-MRSA Hospital-acquired MRSA

The bacteria can cause infection when they enter the body through a cut, sore, catheter, or breathing tube. This infection can be minor and local (for example, a pimple), or more serious (involving the heart, lung, blood, or bone).
MRSA is especially troublesome in hospitals where patients with open wounds, invasive devices and weakened immune systems are at greater risk of infection than the general public.
