What Kills MRSA?

The control and prevention of methicillin-resistant Staphylococcus aureus (MRSA) is very important, especially in a hospital setting. MRSA is one type of Staphylococcus aureus, usually, there are many Staphylococcus aureus living on your skin and in your nose, MRSA is also live among them. These bacteria are quite harmless if you remain healthy and usually do not cause any problem just by living on the skin and nose. However, if MRSA enters the blood through a cut injury or surgical wound or enters the respiratory tract or urinary tract through feeding tubes, catheters or other respiratory supports it can cause serious infections which are fatal. This especially occurs in people who are immunocompromized, misused antibiotics or who are in healthcare facilities. It is a serious infection with a higher morbidity and mortality rate and it is a multidrug-resistant bacterium, it is resistant to all beta-lactams. Therefore, it is important to follow correct control and preventive measure and treatment for MRSA infections.

What Kills MRSA?

What Kills MRSA?

Hand Wash. MRSA is mainly spread by the hands of healthcare providers. Therefore, washing hands after any kind of patient contact are important. With each patient contact, there are about 16 microorganisms per minute coming into contact with the healthcare provider’s ungloved hand and these increases with the increasing patient care time. Wearing gloves can reduce the microorganisms but there can be leaks in the gloves therefore, after each patient contact washing the hands is very important. It should be a thorough wash with proper disinfectants. This is one of the simple ways to prevent MRSA infections and cross infections easily.

Screening And Isolation Of Sources. Regular screening carried on healthcare providers and if they become positive, treatment should be carried out. Patients who become positive can be isolated and nursed separately; however, whether isolation actually helps to prevent the spread of infection is still debatable.

Using Antibiotics Cautiously. One of the main reasons for antibiotic-resistant is the inappropriate use of antibiotics by healthcare providers and by patients on their own. The substandard, excessive and unnecessary use of antibiotics causes resistance in the body. Therefore, healthcare providers should prescribe antibiotics only for the required amount of period and avoid prescribing strong and high-class antibiotics for simple infections. Patients should not use antibiotics excessively.

Staff Education. Educating and training the staff about MRSA infection, recognizing MRSA infection and the methods to prevent and control the MRSA infection is important. The staff also needs to be educated about the prudent use of antibiotics so, that MRSA infection can be reduced.

Improving Health Practices In The Community. Not only in the hospital, but even in the community spread of MRSA should be prevented. Nursing homes, dispensaries, and nurses who do home visits should also practice hand washing techniques as this is the best method to prevent transmission of MRSA infection from colonized and infected people. Proper disinfection of the equipment and place also should be carried out. Patient education regarding the importance of prevention of MRSA infection is also important.

MRSA is spread by:

  • From an infected person’s hands
  • By touching an infected surface or equipment
  • Through skin cuts and open wounds
  • Staying in overcrowded places
  • Inadequate personal hygiene

Treatment Of MRSA Infection

MRSA is carried out by 2% of the normal population and in the infection rates in the ICU setting is more than 60%. So, proper treatment of MRSA is needed. However, the antibiotics mentioned might not work for everyone as certain antibiotics can be resistant.

  • Linezolid
  • Daptomycin
  • Quinupristin
  • Vancomycin
  • Clindamycin
  • Trimethoprim-sulfamethoxazole
  • Tigacil


The control and prevention of methicillin-resistant Staphylococcus aureus (MRSA) is very important, especially in a hospital setting. There are many MRSA living on your skin and in your nose and does not cause any problem. However, if MRSA enters the blood through a cut injury or surgical wound or enters the respiratory tract or urinary tract it can cause serious infections which are fatal. The control and preventive measure are. proper hand wash, screening and isolating sources, using antibiotics cautiously, staff education, and improving health practices in the community. Treatment of MRSA is with antibiotics such as linezolid, daptomycin, vancomycin, clindamycin and trimethoprim-sulfamethoxazole.
