It is undeniable that the recent discovery of antibiotics and disinfectants in the past century is leading to the creation of increasingly dangerous antibiotic-resistant bacteria. Super bugs like Methicillin-resistant Staphylococcus have begun breaking out in hospital areas, killing more and more patients due to the lack of people following through with simple safety measures. In order to stop the creation and spread of antibiotic-resistant super bugs, proper precautions must be taken such as avoiding antibacterial cleaners, following through with instructions when taking prescriptions and maintaining adequate hand hygiene. Through adhering to basic safety rules, the creation and spread of super bugs can be minimized and all together discontinued from occurring at such a rapid rate.
Antibiotic-resistant bacteria are created when mutations in the pathogen's genetic code occurs, changing the protein in the bacteria that the antibiotics normally go after into a shape that the antibiotic can not recognize. The average bacteria divides every twenty minutes, so if a contaminated spot has one single bacteria in the morning, there could be trillions on that same spot at the end of the day. That means that when counting all the possibilities of mutations, the amount of mutated offspring that the bacteria might have formed during those replications could be as high as in the millions. Fortunately though, this does not happen so frequently that it is normally an issue. The amount of non-mutated bacteria vastly outnumbers the mutated ones and many of the mutations occurring in the bacteria usually have either a harmful effect, or not effect at all on its function. That means that the pathogen is still relatively less harmful than it c...

Not only are the descriptions of cases terrifying, but McKenna’s word choice provides the fuel for the fire. The book uses phrases that sound as if they were pulled directly out of a Contagion sequel, such as a rare subcategory of MRSA that manifests as a “flesh eating disease.” “Cloud babies,” is a name given to infected newborns that are capable of spreading MRSA throughout hospital nurseries by shedding the bacteria on microscopic particles,. These erie definitions and surreal scientific evidence work in conjunction with McKenna’s knack for storytelling to paint a picture of the next big
Staphylococcus aureus is a bacteria that is abundant in many places. It can even be found in some of our bodies. These bacteria are harmless as long as none of them are Methicillin resistant Staphylococcus aureus (MRSA). Methicillin is the name of a family of antibiotics that includes penicillin. This MRSA is the deadly superbug that has developed resistant to antibiotics. Statistics show that MRSA contributes to more US deaths than does HIV. It has become a huge threat to every country as the outbreaks can be a surprising one. This threat is caused by the evolution of the bacteria. These superbugs have evolved a resistance of antibiotics which makes them extremely difficult to treat. One article states, “In the early 1940s, when penicillin was first used to treat bacterial infections, penicillin-resistant strains of S. aureus were unknown — but by the 1950s, they were common in hospitals. Methicillin was introduced in 1961 to treat these resistant strains, and within one year, doctors had encountered methicillin-resistant S. aureus. Today, we have strains of MRSA that simultaneously resist a laundry list of different antibiotics, including vancomycin — often considered our last line of antibacterial defense.” [1]
One of the many growing concerns in the world today is antibiotic resistance. Antibiotic resistance happens when the bacteria that an antibiotic is made to treat learns how to fight the treatment, and develops a strain of DNA that resists the antibiotic. The resistance is then spread from generation to generation and from one bacteria to another bacteria. The article “Antibiotic Resistance Is Worrisome, but Not Hopeless” states that the misuse and overuse of antibiotics by humans is one of the reasons for the development of resistance but not the only reason. All in all, antibiotics are important to our country's public health. Education is one way that our country could aid the misuse and overuse of antibiotics that leads to resistance. The
This literature review will analyze and critically explore four studies that have been conducted on hand hygiene compliance rates by Healthcare workers (HCWs). Firstly, it will look at compliance rates for HCWs in the intensive care units (ICU) and then explore the different factors that contribute to low hand hygiene compliance. Hospital Acquired infections (HAI) or Nosocomial Infections appear worldwide, affecting both developed and poor countries. HAIs represent a major source of morbidity and mortality, especially for patients in the ICU (Hugonnet, Perneger, & Pittet, 2002). Hand hygiene can be defined as any method that destroys or removes microorganisms on hands (Centers for Disease Control and Prevention, 2009). According to the World Health Organization (2002), a HAI can be defined as an infection occurring in a patient in a hospital or other health care facility in whom the infection was not present or incubating at the time of admission. The hands of HCWs transmit majority of the endemic infections. As
Antibiotic resistance is a consequence of the misuse of antibiotics that give pathogenic bacteria the ability to withstand the effects of an antibiotic. Resistance occurs when bacteria change in such a way that they survive exposure to antibiotics. Resistance may not be confined to a single antibiotic, but may affect multiple antimicrobial classes. Antibiotic resistance is a major problem and everyone needs to work together to combat it - from medical practitioners to patients.

Resistance arises from mutations that are not under the control of humans, but the evolution of bacteria has been sped along by the overexposure of antibiotics to both people and animals. The number of antibiotic-resistant strains of bacteria in an area is closely related to the frequency that antibiotics that are prescribed (Todar, 2012). Patients often unnecessarily demand antibiotics to treat common colds or simple illnesses that are not caused by bacteria. Instead, these infections are caused by viruses which, unlike bacteria, are unaffected by antibiotics. Incorrect diagnosis can also lead patients to using unnecessary antibiotics, which can sometimes be even more dangerous than otherwise left untreated. Besides the fact that antibiotics kill off beneficial bacteria in the intestines, misuse of antibiotics provides an opportunity ...
New and more effective antimicrobials are developed every year. Many of these are effective in treating common
Resistance first appears in a population of bacteria through conditions that favor its selection. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die. On the other hand, cells that have some resistance from the start or acquire it later may survive. At the same time, when antibiotics attack disease-causing bacteria, they also attack benign bacteria. This process eliminates drug-susceptible bacteria and favors bacteria that are resistant. Two things happen, populations of non-resistant and harmless bacteria are diminished, and because of the reduction of competition from these harmless and/or susceptible bacteria, resistant forms of disease-causing bacteria proliferate. As the resistant forms of the bacteria proliferate, there is more opportunity for genetic or chromosomal mutation (spontaneous DNA mutation (1)) or transformation, that comes about either through a form of microbial sex (1) or through the transference of plasmids, small circles of DNA (1), which allow bacteria to interchange genes with ease. Sometimes genes can also be t...
The cause of acute, persistent, or relapsing clinical infections is often due to multidrug resistance and/or antibiotic tolerance. Pseudomonas aeruginosa is a widespread, opportunistic, gram-negative, bacterial pathogen that readily develops multidrug resistance and is responsible for causing acute and persistent infections (Starkey et al, 2014). P. aeruginosa thrives in moist environments, primarily as waterborne and soil-borne organisms (Chen, 2015). It is found on medical equipment including catheters, which can cause cross-infections in hospitals and lead to nosocomial infections. If P. aeruginosa is found in the lungs, the urinary tract, or the kidneys, the results can be fatal (Chen, 2015). In addition to causing life-threatening diseases,
Antibiotic resistance occurs in bacteria when the use of antibiotics manages to kill off every bacteria except for a lone few. The lone few then live to pass on their DNA every time they undergo binary fission and the antibiotic resistance bacteria spread. This antibiotic resistance has given rise to numerous problems in the medical world as the bacteria they used to handle with a prescription of antibiotics now thrive without barriers. Currently, the main six bacteria that present problems with antibiotic resistance are Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp., collectively known as the ESKAPE pathogens. Collectively these ESKAPE pathogens claim

(2014) shed light on two key components for infection control, which includes protecting patients from acquiring infections and protecting health care workers from becoming infected (Curchoe et al., 2014). The techniques that are used to protect patients also provide protection for nurses and other health care workers alike. In order to prevent the spread of infections, it is important for health care workers to be meticulous and attentive when providing care to already vulnerable patients (Curchoe et al., 2014). If a health care worker is aware they may contaminate the surroundings of a patient, they must properly clean, disinfect, and sterilize any contaminated objects in order to reduce or eliminate microorganisms (Curchoe et al., 2014). It is also ideal to change gloves after contact with contaminated secretions and before leaving a patient’s room (Curchoe, 2014). Research suggests that due to standard precaution, gloves must be worn as a single-use item for each invasive procedure, contact with sterile sites, and non-intact skin or mucous membranes (Curchoe et al., 2014). Hence, it is critical that health care workers change gloves during any activity that has been assessed as carrying a risk of exposure to body substances, secretions, excretions, and blood (Curchoe et al.,
The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
When antibiotics first began to see widespread American usage in the 1940’s, they were heralded as a miracle drug, a description that was not far from the mark considering the great number of debilitating or fatal illnesses that they could rapidly cure. In a time where bacterial diseases that today carry few serious health risks in healthy adults—such as strep throat, ear infections, syphilis, and wound infections—often led to serious debilitation or death, the invention of antibiotics was among the greatest single improvements in public health ever made. And today, more than three quarters of a century after Alexander Fleming discovered the antimicrobial properties of penicillin, antibiotics are as important as ever in maintaining a healthy population, from their ability to treat common infections to the safeguards they provide patients undergoing surgeries and other infection-prone procedures that could otherwise be too risky to perform. However, today many doctors and researchers are beginning to fear that this golden era of antibiotics may be coming to an end due to the ever-increasing threat of antibiotic resistance. There are a number of practices that contribute to increased antibiotic resistance, including the unnecessary prescription, improper dosage, and incorrect usage of antibiotic drugs by humans. But one of the major potential causes of antibiotic resistance does not involve human patients at all. Rather, many believe that the excessive use of antibiotics in food animals is among the leading threats to the future of human ability to fight bacterial infections.
