Some germs that commonly live on the skin and in the nose are called staphylococcus or "staph" bacteria. Usually staph bacteria don't cause any harm. However, sometimes they get inside the body through a break in the skin and cause an infection. These infections are usually treated with antibiotics. 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).

Methicillin-resistant Staphylococcus aureus, or more commonly, MRSA, is an emerging infectious disease affecting many people worldwide. MRSA, in particular, is a very interesting disease because although many people can be carriers of it, it generally only affects those with a depressed immune system; this is why it is so prevalent in places like nursing homes and hospitals. It can be spread though surgeries, artificial joints, tubing, and skin-to-skin contact. Although there is not one specific treatment of this disease, there are ways to test what antibiotics work best and sometimes antibiotics aren’t even necessary.

Ampicillin, penicillin, streptomycin all sulphafurazole all were resistant to the bacteria as it may have grown a mutation.

Methicillin Staphylococcus aureus is defined as strains of bacteria that are resistant to beta-lactam agents, including the synthetic penicillins (eg, methicillin, oxacillin) and the cephalosporins. MRSA can resist the effects of many common antibiotics, so it is difficult to treat. If the infection spreads to the blood stream and becomes systemic may increases risk for life threatening complications. First sign of MRSA are small red bumps that resemble pimples, boils or spider bites. Next they may mature into deep and painful abscesses that require surgical draining. If the bacteria is not confined to the skin and infect the blood stream, causing potentially fatal infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.

Preventable infections regardless of the causative agent, have become major triggers of unintended patient outcome, increased morbidity, and mortality (Arias, 2010). Methicillin Sensitive Staphylococcus Aureus (MSSA) and Methicillin Resistant Staphylococcus Aureus (MRSA) are the most common causes of healthcare associated infections (HAI) and outbreaks in acute care hospitals and community settings (CADTH, 2010). The widespread infection with the MRSA pathogen is believed to have increased from 2.4 percent in 1975 to 29 percent in 1991 and 2003 in hospitals across the United States (U S) (CADTH, 2010). The prevalence is even greater among Intensive Care Unit (ICU) patients at 53 percent (CADTH, 2010) and continues to rise due to the widespread

Antibiotic resistant infections are not only increasing, but intensifying exponentially. Even worse, there are few drugs readily available to diminish the swelling number of contagions; a sparse and meager quantity of combatants to tackle the vehement and aggressive pathogenic bacterium. These microscopic organisms, though infinitesimal, cause gigantic problems and wreak extra havoc when they attack the drugs prescribed to destroy and eradicate them, and survive. In culmination, they are more resilient, more powerful than ever before. Many of these superbugs are stronger and more alive, violently destroying the immune system of the body that has become their habitat, instead of ultimately dying. The tiny,

Cultures are an effective way of guiding the Infectious Disease specialist to which antibiotics that are to be used to treat the patient with MRSA by looking at the type of strain that the patient has. The culture can also be tested for susceptibility to a variety of antibiotics. Surgery may be required to debride and drain the pus filled skin from the infected area, while antibiotics, such as vancomycin, linezolid, daptomycin, quinupristin/dalfopristin, clindomycin (as well as many other sulfa drugs and tetracyclines) could be prescribed to help eradicate the infection. Some antibiotics that are used to treat MRSA are only available intravenously. Unfortunately, some high-powered antibiotics are developing resistance to MRSA infections. Because of this, Vancomycin is no longer a sure treatment for MRSA due to questions surrounding its effectiveness. Patients that are prescribed antibiotics should never stop taking their antibiotics, even if they are starting to feel better. These infections are extremely dormant and are prone to reoccur if they develop resistance to the

Infections caused by antibiotic-resistant strains often occur in epidemic waves initiated by one or a few successful clones. Methicillin-resistant S. aureus (MRSA) is prominently featured during these epidemics. Historically associated with hospitals and other healthcare settings, MRSA now has emerged as a widespread cause of community infections. The majority of Staphylococcus aureus strains are now resistant to penicillin and methicillin (MRSA). Golden staph is creating headlines across the world, the superbug is becoming unstoppable. According to government statistics “one in five cases were resistant to antibiotics” (Alexander, 2017). Scientist are trying to eradicate golden staph with antibiotics, however they are adapting rapidly. Scientists are yet to identify how exactly the bacteria keeps adapting. Antibiotics attack infections by meddling with the bacterial ribosome, which is the part of the cell that makes proteins. If a cell cannot make protein, it dies. “The way the antibiotic works is it throws a spanner in the works. The drug comes in and jams up the machine so the cell can't make protein anymore. “Antibiotic-resistant bacteria find a way to apply oil and restart the machined Belousoff's team compared the cell structure of resistant and non-resistant strains of golden staph under an electron microscope to learn that the latter infections had developed a mutation several

Also, estrogen can have a favorable impact on cholesterol and a positive effect of estrogen on cholesterol values with issues of estrogen maintenance with health risks. Many individuals decide to use tamoxifen to fight estrogenic side effects; when using steroids for long periods of times (What are Steroids).

When penicillin was released to the public in 1944, it was a miracle drug. Infections that had been killers were suddenly treatable. Doctors recommended it generously, both for illnesses that needed it and illnesses that didn’t. Before long, however, it took much stronger doses to see penicillin’s effects. When the antibiotic arms race began in 1944, most physicians assumed that new antibiotics would be discovered or created to keep up with the evolving resistance in bacteria, but the bacteria are constantly evolving new defenses and doctors are starting to run low on antibiotic ammunition. MRSA, methicillin-resistant Staphylococcus aureus, is one of many types of bacteria

Antibiotics have played an essential role in the fight against diseases and infections since the 1940’s. Antibiotics are a leading cause for the rise of global average life expectancy in the 20th and 21st century. They have greatly reduced illnesses and deaths due to diseases. With the introductions of antibiotics in the 1940’s, like penicillin into clinical practice, formally deadly illnesses became immediately curable and saved thousands of lives (Yim 2006). Antibiotic use has been beneficial and when prescribed and taken correctly their effects on patients are exceedingly valuable. However, because these drugs have been used so widely and for such a long period of time the bacteria that the antibiotics are designed to kill have adapted,

Methicillin resistant Staphylococcus aureus (MRSA) has been a type of multidrug resistant organism and staph bacteria known to cause serious infection that can lead to long hospitalizations and death. It can begin as a simple infection on skin or in the lungs, and if left untreated, can lead to traveling to the bloodstream and causing sepsis (“Methicillin-resistant Staphylococcus aureus (MRSA), 2015”). The Centers for Disease Control and Prevention reports that 33 percent of individuals carry the staph bacteria intranasally and two percent of individuals carry MRSA (“Methicillin-resistant Staphylococcus aureus (MRSA), 2015”). Even though this is a serious issue among healthcare settings all over the country, the number of people affected

in vivo and a viable candidate for antimicrobial repurposing (4). Drug repurposing is a means of finding new antimicrobial agents for the emergence of drug resistant bacteria. Celecoxib, an anti-inflammatory drug, combined with ampicillin, an antibiotic, treated infection and reduced inflammation resulting from Staphylococcus aureus via sirtuin1 (SIRT1), an inflammation regulator. Recent studies of the antimicrobial effects of Celecoxib have led to its repurposing as a potential antimicrobial agent in the treatment of polymicrobial sepsis when used in combination with an antibiotic. The study focused on two antibiotics; Imipenem and Ampicillin.4, 5

Of particular interest are those chemicals, which mimic the female hormone of estrogen, which is

Take for example MRSA (Methicillin-resistant Staphylococcus aureus), a S. aureus strain that was discovered in 1961 to be resistant to the antibiotic methicillin. Webmd indicates that MRSA has now grown its resistance from methicillin to “amoxicillin, penicillin, oxacillin and many other common antibiotics” (MRSA). This increase in resistance of a methicillin-resistant strain of S. aureus can be attributed to the increasing use and overuse of antibiotics, not only in the doctor’s office but also in agriculture. MRSA is only one of many antibiotic resistant strains of bacteria. New resistant strains are evolving rapidly. According to Dr. Ed Warren, “there are high levels of antibiotic resistance in bacteria causing common infections (e.g. urinary tract infections, pneumonia, bloodstream infections) in all regions of the world” (21).
