Antibiotics also kill the healthy bacteria in your body. Dr. Martin Blaser states “evidence…suggests antibiotics may permanently change the beneficial bacteria that we’re carrying” (Conley, 2011, para. 3). Antibiotics cannot differentiate beneficial bacteria from harmful bacteria. By taking unwarranted antibiotics, individuals destroy healthful bacteria in the gastrointestinal tract.
Thanks to humans being so ignorant and continuously burning through our ozone layer, therefore, allowing more ultraviolet rays in, viruses are slowly desiccated if they are not already living in a host. If a virus infects the human, the spread of infection begins through blood, saliva, or being bitten by one of the infected. There ... ... middle of paper ... ...able to control it. The virus will take a mind of its own and start with the control of the human host. Biological science does pose a potential threat to humanity.
The Resistance Against The Resistance Antibiotic resistance is when certain antibiotics lose their ability to render harmful pathogens inactive. When bacteria become resistant to antibiotics they will continue to grow and multiply without the antibiotics having any effect on them. Bacteria that are resistant to antibiotics are called superbugs because they are very hard to be destroyed within the body. Antibiotic resistance can be caused by many things. The most common way in which bacterium build up a defence to antibiotics is by mutation.
Some call it “horror'; and some call it “the super germ';, but now, our always known “regular'; bacteria, those one-celled creatures once considered under control with antibiotics, have invaded our hospitals and headlines with a vengeance. The vengeance used against us is caused by an existing organism called necrotizing fasciitis, the so-called flesh-eating bacteria, caused by Group A streptococcus. What this organism does is progressively destroy the human body tissue all the way to the bone. This organism has amazingly outsmarted us of even our most potent drugs. In our community right now, medical researchers are testing antibiotics that may have chemicals to disable the resistance of this organism.
Microorganisms that can produce genes to combat antibiotics survive and reproduce, and those that cannot die, leaving only the resistant bacteria. Resistance is very versatile and can come in many forms, including preventing the entry of the antibiotic, exporting the antibiotic, or producing enzymes that can degrade the antibiotic. Resistance also includes the ability to modify the antibiotic target, thereby rendering it useless. An example of the inactivation of antimicrobial drugs can be seen in the resistance of bacteria with a beta lactam ring structure; these bacteria have developed enzymes such as beta-lactamases that degrade and inactivate antibiotics targeting their ring structure. Some evidence exists supporting the claim that antimicrobial substances exist naturally in the environment, contributing to resistance; however, there is more evidence supporting the claim that overuse of drugs, agriculture, and many other human uses are feeding resistance.
Following some statistical facts, they talk about how they can now take the DNA and figure out what microbial produced it. This lead into some of the benefits of bacteria, such as decomposing garbage and producing oxygen. Later it talked, and had a graphic, about individual bacterias that offer benefits to humans. It goes into how microbes are constantly attacked by humans by using products such as soap, anti-bacterial rinses, cat litter, etc. Then it concludes that section of the article saying that by killing off so many bacteria, both good and bad, it could upset the balance of nature, not only resulting in direct harm to us, but allowing other bacteria to become dangerous.
S. aureus is both pathogenic and opportunistic, taking every chance it gets to evolve and become more infectious. While it is found in the normal flora of the human skin, it is not until it invades the body and becomes truly pathogenic that a person should worry about this fact. So if it is on the skin, all it needs is a break in the skin or an opportunity to invade the host cells and do the damage. If there is a cut in the skin and the bacteria make it inside or even worse, into the bloodstream, they attack the cells and spread throughout the body. There are other situations in which this bacteria could become resistant and once it has, virulence factors help it to invade and spread rapidly.
Explaining to the patient why antibiotics won’t work for them and also explaining what the side effects of the antibiotic would cause to them, specifically is important to help patient understand why an antibiotic is not need and also helps reduce antibiotic resistance. We are an instant gratification society and patients often view antibiotics as a quick fix, we must educate, educate, educate to protect our patients and the world as a whole against antibiotic resistance.

Introduction: Antibiotics have the ability to kill or hinder the growth of bacteria. Antibiotics contain compounds that are naturally produced by organisms to combat diseases caused by microbes. Discovery of penicillin by Sir Alexander Fleming became the first stepping stone of many new antibiotics of today’s modern medicine. Antibiotics typically invade the very components that make up bacteria, such as cell walls and metabolic pathways (Sato et al., 2014). However, frequent mutations of bacteria cause today’s strains to become more resistant.
It is very contagious, and pyogenes travels quickly through places where bacteria flourish, such as schools and health institutions. The body cannot fight this bacterium very well without help, and S. pyogenes was a common cause of death until the introduction of antibiotics in the twentieth century. It has a number of ways to subdue the immune system, but it is almost completely vulnerable to penicillin, even after decades of exposure. While generally no more than a nuisance, this bacterium continues to be an interesting topic of discussion. (6,3,2) General Contraction: Streptococcus pyogenes is thought to live benignly within one in five people, and is thusly one of the most common pathogens among humans.
