Mrsa deadly bacteria
MRSA is the acronym for methicillin-resistant Staphylococcus aureus. MRSA is a “staph” microbe (bacteria) that does not get better with the type of antibiotics that normally cure staph infections.
Most staph is spread by skin-to-skin contact (touching). A doctor, nurse, other health care providers, or visitors to the hospital may have staph in their body that can be spread to a patient.
MRSA infections can also occur in healthy people who have not recently been in the hospital. Most of these infections are on the skin or, less often, in the lungs. People who may be at risk include:
MRSA infection in people in medical facilities tends to be serious. These infections can be in the bloodstream, heart, lungs or other organs, urine, or at the site of recent surgery. Some symptoms of these serious infections may include:

This disease is usually localized to the skin and soft tissues and causes localized abscesses that can be treated with the antibiotics to which MRSA still responds, vancomycin and rifampicin. However, in some cases, MRSA degenerates into necrotizing fasciitis and when it enters the bloodstream it spreads throughout the body. Mortality in these cases rises to about 30 %.
“This technique is very powerful as it combines the location and timing of immune responses in live animals. Unfortunately, our initial goal, which was to investigate the role of MSPs in skin infections, proved too complicated to study using skin imaging because collagen and fat prevented us from obtaining relevant data with SD-IVM. Our interest then turned to staphylococcal bacteremia and its influence on the liver,” explained Dr. Surewaard.
By injecting MRSA into the bloodstream, Dr. Surewaard found that the Kupffer cell, a specialized macrophage located in the liver, captured 90% of the bacteria. He then devoted his research to finding out how these bacteria do or do not survive the Kupffer cells and the mechanisms involved.
Staphylococcus aureus is sexually transmitted
Methicillin-resistant Staphylococcus aureus infection is caused by a type of staph that has become resistant to many of the antibiotics used to treat common Staph infections.
Most methicillin-resistant Staphylococcus aureus infections occur in people who have been in hospitals or other health care settings, such as nursing and convalescent homes and dialysis centers. When it occurs in these settings, it is referred to as healthcare-associated methicillin-resistant Staphylococcus aureus. Healthcare-associated methicillin-resistant Staphylococcus aureus infections are usually associated with invasive devices or procedures, such as surgeries, intravenous catheters or artificial joints. Healthcare-associated methicillin-resistant Staphylococcus aureus infection can be transmitted by healthcare providers touching people with dirty hands or by people touching dirty surfaces.
Meaning of MRSA
MRSA is usually spread by contact with infected skin. In addition, it can be spread through contact with materials or surfaces that have come in contact with something infected (e.g., towels, clothing, faucets, doorknobs).
MRSA skin infections can occur in any work environment. However, certain factors can be conducive to the spread of MRSA. Risk factors are summarized as follows: crowds, frequent contact with other people’s skin, affected skin condition (cut, scrape or rash), contaminated items and surfaces, and poor hygiene.
Workplaces where these factors frequently occur include: schools and child care centers, student dormitories, military barracks, and correctional institutions.
Cleaners and disinfectants can cause irritation and may even be responsible for contributing to health problems such as asthma or skin conditions, so it is important to follow label instructions and use them accordingly.
