Antibiotic Resistant Bacteria Essay

732 words - 3 pages

Bacteria refer to a large domain of prokaryotic microorganisms (microscopic organisms that lack a membrane bound nucleus). They are very abundant in nature. For example, according to Christian Nordqvist (2009), a gram of soil can contain up to forty million bacterial cells. Bacterial microorganisms can be found almost anywhere and can adjust extremely well to surrounding conditions.
Not all bacteria are harmful and even play an important role in the recycling of nutrients. By recycling nutrients bacteria become a valuable resource for the human body. Large colonies of bacteria called probiotics are contained in our large intestine, where they are responsible for producing vitamins that our bodies need to survive. Even though the majority of bacteria in the body are valuable and harmless there exists another type of bacteria that has quite the opposite role. These microbes are called pathogenic bacteria. Pathogenic bacteria are the type of bacteria responsible for infections and diseases. They invade a host, reproduce, and cause the infected host harm. According to the Washington State Department of Health, Tuberculosis is one of the most common fatal diseases caused by pathogenic bacteria. It is primarily treated with a course of strong antibiotics to fight the infection. Antibiotics inhibit the growth of bacteria, and are used to treat infections. They target not only pathogenic but also probiotic bacteria. Other common ways bacteria are neutralized are by the use of disinfectants, high heat, and ultraviolet irradiation.
When bacteria no longer respond to methods of neutralization they are said to be resistant. In modern times bacterial organisms have become resistant to treatments of antibiotics. It is not as if there is only one kind of antibiotics, but many different kinds varying in strength and effectiveness. When pathogenic bacteria become able to withstand more than one different treatment they are called multidrug resistant bacteria. These multidrug resistant bacteria are becoming a serious concern in the modern-day medical field. The Center of Disease Control (C.D.C) has gone as far as prioritizing bacteria as “urgent, serious, and concerning”. The C.D.C. (2013) states, “In the United States, more than two million people are sickened every year with antibiotic-resistant infections, with...

Healthcare workers play an important part in preventing antibiotic resistance which can be done through providing education on antibiotic usage and the prevention of antibiotic resistant organisms. In the article by Aziz (2013), several issues have been identified relating to antibiotic resistance, antibiotic structure and function and the properties which lead to bacteria becoming resistant.

1400 words - 6 pages Penicillin was the first antibiotic discovered. Soon more and more antibiotics were developed. The excess amounts of these antibiotics have caused many bacteria to produce strains that are resistant to antibiotics (Nicolaou). During the last decade, there has been a shocking increase in the appearance of antibiotic-resistant bacteria because of an increased use of antibiotics combined with the extraordinary ability of bacteria to develop

It

Bacteria acquire genes for resistance in three ways. In spontaneous mutation, bacterial DNA may change spontaneously, as indicated by the starburst. Drug-resistant tuberculosis arises this way. In a form of microbial sex called transformation, one bacterium may take up DNA from
