“The new community associated MRSA strains appear to be more virulent and more easily spread between people”, says Dr Marina Morgan from the Royal Devon & Exeter Foundation NHS Trust. “These community associated versions have been found in people with few, if any, reasons to have MRSA. Typically they haven’t recently been in hospital, or and are not looking after or living with people with MRSA.”
Although more antibiotics are still effective against community MRSA than against the hospital MRSA, the community associated infections are often more virulent. Most can also produce a toxin called Panton-Valentine leucocidin, or PVL, that kills white blood cells – our bodies’ key defence against invasive bacteria.
“Although the resistant strain is not yet widespread in the UK, we have seen increasing numbers of PVL- toxin producing Staphylococcus aureus infections, mainly presenting with recurrent boils and abscesses. This excessive production of white cells to compensate for those killed by the PVL toxin leads to recurrent severe boils and abscesses. The MRSA is easily spread by close contact, such as in families, nurseries and athletic teams”, says Dr Morgan. “These new strains of bacteria appear to be able to stick to damaged skin and airways better than hospital MRSA strains, and they also multiply at a faster rate.
A minority of patients carrying these PVL-producing staphylococci can suffer severe invasive infections such as septicaemia or a lethal form of pneumonia where the lung tissue itself is destroyed by the toxins. With this type of necrotising PVL pneumonia, even with the strongest antibiotics, more than 60% of otherwise healthy young and fit people will die”.
So far community associated MRSA strains are mainly spreading in America, where they are a major cause of infection in children. Whilst doctors do not know if the bacteria could spread as rapidly in the UK, they are already worried. These new strains of bacteria appear to be able to stick to damaged skin and airways better than hospital MRSA strains, and they also multiply at a faster rate.
“These infections are easily missed clinically, where they can be dismissed as just recurrent boils and overlooked until a serious infection develops”, says Dr Morgan. “Then, with severe invasive infections like pneumonia, early diagnosis is vital as treatment with the correct antibiotics and massive doses of immunoglobulin can save children’s lives”.
If the community associated MRSA strains take hold and spread in the UK as they have in the USA then many more patients with unsuspected MRSA will be admitted to hospitals, given the wrong antibiotics, and when doctors finally realise the infection is MRSA, by the time patients get the correct treatment it may be too late.

For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material chromium triiodide. In addition, they found a long-sought explanation for the unusual magnetic properties of the material. The journal Science has published the findings.
The use of atomically thin, two-dimensional van der Waals materials promises innovations in numerous fields in science and technology. Scientists around the...
Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.
It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.
Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.
Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...
