Antibiotic Sensitivity

Antibiotic Sensitivity Lab Report: Microbes with an Emphasis on E. col Microbiology 225 March 25, 2011 Abstract Antibiotics argon a major(ip) 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 vizor electric resistance of microorganisms to antibiotic 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 granted four varied bacteria to study resistance utilise 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. distributively bacterium had a variant reaction to each antibiotic that was placed on the nutrient agar plate. Viewin g the different reactions that Escherichia coli had to each antibiotic helped us recognize a picayune more about bacteria that are gram blackball vs. gram positive bacteria. Introduction The past carbon has seen spectacular increases in the technology and science of the medical world with the husking of antibiotics marking a new era for combating erstwhile feeling 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 creation misused, many micro bacteria are nice resistant to once effective drugs. A useful test in measuring the effectiveness of antib! iotics 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 entrust see a clearing or corona approximately the disk; this is called the zone of inhibition. These zones will vary in surface depending on antibiotic sensitivity...If you want to get a liberal essay, order it on our website: OrderEssay.net
