MRSA infection is caused by Staphylococcus aureus bacteria — often called "staph." MRSA stands for methicillin-resistant Staphylococcus aureus.
It's a strain of staph that's resistant to the broad-spectrum antibiotics commonly used to treat it. MRSA can be fatal.

Northern Ireland scientists find a new weapon in MRSA war

The following report was taken from two sources:
The Worldview blog
A new weapon that could help wipe out the deadly MRSA virus has been developed by researchers from Northern Ireland.
Experts from Queen’s University have discovered new agents that can kill colonies of MRSA and other antiboitic resistant hospital-acquired
The antimicrobial agents also prevent any growth of the potentially lethal bacteria.
The breakthrough was made by a team of eight researchers from the Queen's University Ionic Liquid Laboratories (QUILL) Research Centre led by Brendan
Gilmore, a lecturer in Pharmaceutics, and assistant director of QUILL Dr Martyn Earle. The discovery has been published in the |scientific journal,
Dr Earle said: “We have shown that, when pitted against the ionic liquids we developed and tested, biofilms offer little or no protection to MRSA,
or to seven other infectious microorganisms.
“Our goal is to design ionic liquids with the lowest possible toxicity to humans while wiping out colonies of bacteria that cause hospital acquired
Many types of bacteria, such as MRSA, exist in colonies that stick to the surfaces of materials. The colonies often form coatings, known as biofilms,
which protect them from antiseptics, disinfectant, and |antibiotics.
Ionic liquids, just like the table salt sprinkled on food are salts. They consist entirely of ions — electrically-charged atoms or groups of atoms.
Unlike table salt, however, which has to be heated to over 800 degrees celsius to become a liquid, the ionic |liquid antibiofilm agents remain |liquid
at the ambient temperatures found in hospitals.
One of the attractions of ionic liquids is the opportunity to tailor their physical, chemical, and biological properties by building specific features
into the chemical structures of the positively-charged ions (the cations), and/or the negatively-charged ions (the anions).
Microbial biofilms are not only problematic in hospitals, but can also grow inside water pipes and cause pipe blockages in industrial processes.
Mr Gilmore added: “Ionic liquid based antibiofilm agents could potentially be used for a multitude of medical and industrial applications. For
example, they could be used to improve infection control and reduce patient morbidity in hospitals and therefore lighten the financial burden to
healthcare providers. They could also be harnessed to improve industrial productivity by reducing biofouling and microbial-induced corrosion of
