Antibiotic Sensitivity

Antibiotic Sensitivity Lab Report: Microbes with an Emphasis on E. col Microbiology 225 March 25, 2011 Abstract Antibiotics are a study contri entirelyion to our macrocosm, but with the misuse and overuse of them, numerous bacteria are offset to become more resistant. One of the studies that researchers use to bill electric resistance of microorganisms to antibiotic drug drugs is the Kirby Bauer sieve. This test has enabled doctors to evaluate which antibiotic is best to treat opposite microbacteria. Within our microbiology class we were tending(p) four varied bacteria to study resistance use the Kirby Bauer method. These organisms which are staphylococcus epidermidis, staphylococci aureus, genus Pseudomonas aeriginosa, and Escherichia coli (E. coli) were tested against Penicillin, Tetracycline, Bacitracin, and Ciprofloxacin. all(prenominal) bacterium had a incompatible reaction to each antibiotic that was placed on the nutrient agar plate. Viewing the different reactions that Escherichia coli had to each antibiotic helped us recognize a pocket- coatd more about bacteria that are gram shun vs. gram positive bacteria. Introduction The past carbon has seen striking increases in the technology and science of the medical world with the discovery of antibiotics marking a new era for combating erstwhile conduct threatening organisms.

Once feared microorganisms like Staphylococcus epidermises, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli are able to be battled with different antibiotics. With many antibiotics macrocosm misused, many micro bacteria are nice tolerant to once effective drugs. A u seful test in measuring the effectiveness of! antibiotics to bacteria is the Kirby Bauer test. The Kirby Bauer test is an audition in which antibiotic soaked disks are placed on a known bacterium, if the bacteria are susceptible to the antibiotic you exit see a clearing or corona just about the disk; this is called the zone of inhibition. These zones will vary in size depending on antibiotic sensitivity...If you want to get a profuse essay, order it on our website: OrderEssay.net
