An increasing number of people are being diagnosed with skin infections caused by Staphylococcus aureus (“staph”) bacteria that are resistant to many antibiotics (drugs that kill bacteria). These resistant strains of staph are known as “MRSA” (methicillin-resistant Staphylococcus aureus).
When common antibiotics don't kill the staph bacteria, it means the bacteria have become resistant to those antibiotics. This type of staph is called MRSA (Methicillin-Resistant Staphylococcus aureus). MRSA was first identified in the 1960's and was mainly found in hospitals and nursing homes.
What is the treatment for MRSA? Although MRSA cannot be effectively treated with antibiotics such as methicillin, nafcillin, cephalosporin or penicillin, it can usually be treated with an antibiotic called vancomycin.
Called sepsis, this infection can lead to septic shock. This is a life-threatening episode when your blood pressure drops to an extremely low level. Staph infections can also turn deadly if the bacteria invade deep into your body, entering your bloodstream, joints, bones, lungs or heart.
Staph can cause serious infections if it gets into the blood and can lead to sepsis or death. Staph is either methicillin-resistant staph (MRSA) or methicillin-susceptible staph (MSSA). Staph can spread in and between hospitals and other healthcare facilities, and in communities.
Infections of the skin or other soft tissues by the hard-to-treat MRSA (methicillin-resistant Staphylococcus aureus) bacteria appear to permanently compromise the lymphatic system, which is crucial to immune system function.
Each case of staph infection is different, but most often staph will resolve in 1-3 weeks. Once you complete your antibiotic treatment, you'll no longer be contagious, but you should keep any skin infection clean and covered until it is completely gone.
Sepsis, which is an infection of the bloodstream, and one of the most dangerous forms of staph infection. Symptoms include rapid breathing, an elevated heart rate, fever, chills, and disorientation. Staph infections in bones which also cause fever and chills accompanied by pain in the infected area.

Mechanisms of resistance.
Staphylococcal resistance to penicillin is mediated by blaZ, the gene that encodes β-lactamase (Figure 2a). This predominantly extracellular enzyme, synthesized when staphylococci are exposed to β-lactam antibiotics, hydrolyzes the β-lactam ring, rendering the β-lactam inactive.
Antimicrobial resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Resistant infections can be difficult, and sometimes impossible, to treat.
Doctors often prescribe antibiotics for 7 to 10 days, although they may be taken for longer periods, depending on how the infection responds. Most people who take antibiotics for a staph infection feel better in two or three days. Still, it is important to finish the prescription.
In some cases, the antibiotic-resistant illness can lead to serious disability or even death. Resistance can happen if the bacterial infection is only partially treated. To prevent this, it is important to finish taking the entire prescription of antibiotics as instructed, even if your child is feeling better.
For serious staph infections, vancomycin may be required. This is because so many strains of staph bacteria have become resistant to other traditional antibiotics. This means other antibiotics can no longer kill the staph bacteria.
Summary: Staphylococcus aureus bacteremia (SAB) is an important infection with an incidence rate ranging from 20 to 50 cases/100,000 population per year. Between 10% and 30% of these patients will die from SAB.
Invasive staph infections, such as sepsis (also called septicemia), endocarditis, and pneumonia, typically cause significant illness that may include fever, fast breathing or shortness of breath, fatigue, and sometimes confusion or disorientation.
If a systemic staph infection develops in the heart, lungs, bloodstream, or another organ system, treatment can take weeks to months. In rare cases, these staph infections can lead to sepsis, a dangerous condition in which the immune system has an exaggerated response to infection.
If the sore becomes unusually painful or red, get prompt medical attention. If red lines develop, that's a sign the infection is spreading and needs immediate medical attention.
Widjaja Foundation Inflammatory Bowel and Immunobiology Research Institute and departments of Biomedical Science and Medicine. As a result, the body does not develop long-term immunity and remains vulnerable to that particular staph infection throughout life.
Research on people has shown that carrying staph bacteria is linked to autoimmune diseases such as psoriasis, Kawasaki disease and graulomatosis with polyangiitis.
Antibiotic resistance is rising to dangerously high levels in all parts of the world. New resistance mechanisms are emerging and spreading globally, threatening our ability to treat common infectious diseases.
Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; (4) active drug efflux.
