Antibiotic Resistance in Bacteria - PROLIFIC ESSAYS.
At present antibiotic resistant poses as a massive challenge for modern medicine. There is a wide variety of conditions that antibiotic resistance stands in the way of successful treatment like tuberculosis (TB) and Methicillin-resistant Staphylococcus aureus (MRSA). As we know TB is a disorder affecting the lungs and also the rest of the body.
Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful.Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However, there are some that can cause infections. As bacteria are exposed to antibiotics over time, resistance may develop, and the.
Keywords: antibiotic resistance essay, antibiotic resistance mechanism A challenge for modern medicine. Antibiotic resistance is a serious matter which should be addressed seriously. Every time you take antibiotics you don’t need you increase your chance of contracting an infection that is caused by bacteria that are resistant to antibiotics.
Antibiotic Resistance in Bacteria For over 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases.
Antibiotics are mainly used to eliminate bacteria by killing them. They also inhibit the growth of bacteria. There are various antibiotics which are used for several diseases. In the process of eliminating bacteria, some of them adopt mechanism and evade the risk of death.
The current increase in bacterial and fungal pathogens that are resistant to antibiotics and antifungal drugs, respectively, is of major concern in this post-antibiotic era (Davies and Davies, 2010; Bush et al., 2011; Coates et al., 2011;CDC.
As the antibiotics kill off the bacteria that are sensitive, a few resistant cells remain. These cells then reproduce and horizontally transfer immune genes to surrounding bacteria. As a result, antibiotic resistance has increased due to the overuse in farms along with the overuse in people.
Antibiotic resistance can occur by a mutation of DNA in bacteria or DNA acquired from another bacteria that is drug-resistant through transformation. Penicillin-resistant bacteria can alter their cell walls so penicillin can not attach to it. The bacteria can also produce different enzymes that can take apart the antibiotic.
Amongst the antibiotics discovered by Fleming is penicillin. In his studies, he used a contaminated penicillin mold. In this study, he observed staphylococci inhibition on an agar plate. Fleming discovered bacteria resistance to penicillin since there was mold growth.

Antibiotic Resistance - Essay Example Pages: 2 (522 words) Published: May 11, 2012 For some reason, when I think about evolution I think about monkeys; never did I think about a mutating mold or ever-changing bacteria.
Such bacteria become resistant to the antibiotics by virtue of such inactivating enzymes. The natural antibiotics, i.e. those produced by different organisms, sometimes do not possess all the desirable properties. They have to be chemically modified to give these properties. Such modified antibiotics are called semi-synthetic ones.
Controlling Antibiotic Resistance: A Literature Review Antibiotic resistance can be attributed to both overuse and incorrect use of antibacterial medications. Resistance spreads more quickly when antibiotics are used frequently, or if the patient does not complete the prescribed course (Aziz, 2013).
