MRSA infection spread Most often, the infection spreads by skin-to-skin contact or through contact with items contaminated by the bacteria. Treatment Although MRSA is bacteria methicillin-resistant, it can often be treated with another type of antibiotic. For effective MRSA treatment, the infection must be caught and treated as early as possible.

Prevention Not all infections can be prevented, but the chances of spreading infections can be greatly reduced by following these tips: Wash your hands often, particularly if you are in a healthcare facility. Keep wounds clean and covered. What makes S. Most importantly, S. Methicillin is a penicillinase-resistant penicillin derivative that was developed as a response to the global spread of the penicillinase gene among S.

However, methicillin-resistant S. Nevertheless, hospital-associated cases still represent the by far greater source of morbidity and death among MRSA infections. Over time, we have seen the disappearance of the original s and the surge of novel MRSA clones, which was accompanied by the appearance of new types of SCCmec, the mobile genetic element that harbors the methicillin resistance gene, mecA.

Infections with that clone were limited mostly to Europe. These clones still are among the most frequently isolated HA-MRSA clones today and belong to only about five clonal groups. These types are smaller compared with other types of SCCmec, cause less of a fitness cost, and thus likely contribute to the capacity of CA-MRSA to spread and infect healthy people.

The molecular basis of virulence and spread of MRSA has recently received much attention. This suggests that molecular factors other than only such contributing to aggressive virulence are behind the epidemiological success of HA-MRSA.

It has frequently been proposed that HA-MRSA clones thrive in the hospital environment due to an exceptional capacity to colonize patients and hospital personnel. However, researchers have not yet been able to link a colonization factor to the spread and success of an MRSA clone. The importance of a recent study by Li et al. Evaluating data from three large teaching hospitals in eastern China, they showed that the frequency of sasX -positive HA-MRSA infections increased significantly over the last decade.

Interestingly, no ST clones were found among community isolates from healthy individuals in the same region, underscoring that this ST is specifically adapted to the hospital environment. More importantly, however, they exemplify how a colonization factor may contribute to the epidemiological success of a newly arising MRSA clone. In accordance with the capacity of prophages to be mobilized and transferred to other strains, Li et al.

These red bumps can quickly turn into deep, painful boils abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin. But they can also burrow deep into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs. Keep an eye on minor skin problems — pimples, insect bites, cuts and scrapes — especially in children.

If wounds appear infected or are accompanied by a fever, see your doctor. Different varieties of Staphylococcus aureus bacteria, commonly called "staph," exist.

Staph bacteria are normally found on the skin or in the nose of about one-third of the population. The bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they usually cause only minor skin problems in healthy people. MRSA is the result of decades of often unnecessary antibiotic use. For years, antibiotics have been prescribed for colds, flu and other viral infections that don't respond to these drugs.

Even when antibiotics are used appropriately, they contribute to the rise of drug-resistant bacteria because they don't destroy every germ they target.

Bacteria live on an evolutionary fast track, so germs that survive treatment with one antibiotic soon learn to resist others.
