Antimicrobial Agents Lisette Vazquez October 27, 2013 Antimicrobial Agents Antimicrobial agents are utilized to kill microorganisms that cause infections. In order to be able to kill these microorganisms we must have an understanding of the factor associated with the infection. The purpose of this paper is to explore the different types of antimicrobial agents and the differences between viral and bacterial infections. Antimicrobial Agent Categories There are several antimicrobial agents to treat infections. Beta-lactams are the types ending in â€Å"illin† and those beginning with â€Å"ceph† or â€Å"cef† such as penicillin and the cephalosporin. The mechanism of action is the inhibition of bacterial cell growth by†¦show more content†¦It is critical to isolate the specific pathogen in many serious, life-threatening infections, especially for situations that are likely to require prolonged therapy (e.g., endocarditis, septic arthritis, disk space infection, and meningitis) (Leekha, Terrell Edson, 2011). The timing of the initial therapy should be determined based on the urgency of the situation. The selection of proper antimicrobial agent is essential to obtain the best results. Inappropriate use of antibiotics has helped create strains of bacterial disease that are resistant to treatment with different types of antibiotics medication (Masterton, Drusano, Paterson, Park, 2008). When antimicrobial agents are not used properly there are consequences such as the body killing the beneficial bacterial that normally reside in the body. When this occurs the body become resistant to treatment of deadly illnesses. Summary Proper selection of antimicrobial agents to treat infections is essential in order to avoid overuse of antibiotics. Prior to prescribing antibiotics it’s important to accurately diagnosis the infection, defining the host, need for and timing of therapy. Understanding the different types of antimicrobial agents and its mechanisms is important to initiate therapy because lab results are not readily available.Show MoreRelatedThe Discovery Of Antimicrobial Agents2921 Words   |  12 PagesAbstract The discovery of antimicrobial agents for the treatment of infectious diseases has been heralded as one of the greatest medical achievements of the 20th century. However, use, misuse, and abuse of antimicrobial agents has led to an increase in the population of antimicrobial-resistant bacteria and has become a major public health threat the world over. Unfortunately the pace of developing new treatments has not kept pace with the growing problem, leading to increased mortality and morbidityRead MoreEfficacy Of Tea Tree Oil1722 Words   |  7 Pagesefficacy of naturally occurring antimicrobials against common bacteria located in a normal human microbiome. Three antimicrobials, Melaleuca alternifolia (tea tree) oil, commercial honey, and Capsicum annuum (red chili pepper), were tested on the gram negative Escherichia coli and the gram positive Staphylococcus epidermidis bacteria. Quantitative data was taken using the filter-paper disk method to determine the zones of inhibition produ ced by the three antimicrobials. The results collected showedRead MoreThe Antimicrobial And Antioxidant Activities1717 Words   |  7 PagesMedicinal plants are used traditionally in the treatment of various kinds of diseases since time immemorial. The present study was carried out to evaluate the antimicrobial and antioxidant activities of leaves from Elephantopus scaber by using different solvents (ethyl alcohol, acetone and aqueous). The ethyl alcohol, acetone and aqueous extracts of leaves were subjected to phytochemical analyses, which revealed the presence of alkaloids, phenols, flavonoids, saponins, steroids, tannins, coumarinsRead MoreREVIEW - Phytochemical Screening and Extraction4270 Words   |  18 Pagesonline http://www.ipharmsciencia.com  ©2011 IPS REVIEW ARTICLE Phytochemical screening and Extraction: A Review ABSTRACT Plants are a source of large amount of drugs comprising to different groups such as antispasmodics, emetics, anti-cancer, antimicrobials etc. A large number of the plants are claimed to possess the antibiotic properties in the traditional system and are also used extensively by the tribal people worldwide. It is now believed that nature has given the cure of every disease in oneRead MoreEssay about Acid/ Base properties of an antimicrobial agent863 Words   |  4 PagesChem 253 Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium benzoate. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic pH. Rather than benzoic acid, sodium benzoate is used because it is generally soluble in most aqueous solutions but benzoicRead MoreSpices And Its Effect On Food899 Words   |  4 Pagestastes like spicy or sour. The spices back then would be cherished as tradeable goods to other countries for a trade of currency, but soon the early cultures found out that the spices they were trading could be used to prevent food spoilage. As an antimicrobial, many spices could be helpful to get rid of the bacteria that can be found on food, or to preserve the food as well. Bacteria can spread from anywhere, through the air, from the ground, and even from a person’s hands right when food is about toRead MoreSample Characterization, Identification And Performing Antibiotic Susceptibility Testing Essay2101 Words   |  9 Pagesbe stored in brain heart infusion broth with 20% glycerol and stored frozen without significant loss of viability at -20ââ€" ¦C until further study (Koneman et al.. 1992). 7.

Another source of many toxic ingredients are in preservatives added to cosmetics. Preservatives are antimicrobial chemicals that are added to food pharmaceuticals and cosmetics to prevent spoilage. No ideal preservative has been found because many preservative has been classified as irritants (Lee, An, Choi, Moon, Chang, 2007, p. 135).
