In addition, streptomycin has similar properties to beta-lactam antibiotics such that it can modify the permeability of the bacteria’s wall itself, allowing faster diffusion across the membrane (Davis…
However, my predictions on the order of highest to lowest zone of inhibition for the three antibiotics were proven wrong. Instead of the order neomycin, erythromycin, and tetracycline, results from figure 3 shows erythromycin, tetracycline, and then neomycin in the order of highest zone of inhibition to lowest. These predictions that was base on previous experiments from (Mcbride et al 2007) and (Wendelbo et al., 2003) were falsified. There is however limitation to my experiment because of the small sample size that consisted only of five agar trays. If more trials were done, we may get results closer to the sources.…
Introduction: The effectiveness of Antimicrobial agents against Microorganisms Population of microorganisms or growth are killed and/or inhibited by natural or synthetic chemical antimicrobial controls (Madigan, et al 2012). Antimicrobial agents are grouped according to their efficacy against microorganisms. Bactericidal that kill and bacteriostatic prevent and/or reduce growth (Madigan et al, 2012).…
The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in the microbiology laboratory during the semester that was performed to test ones practical understanding of microbiology. The sole purpose of the unknown lab is to demonstrate understanding of the experimental methods and lab techniques learned during…
The different products used are put into 2 types of categories. The first category was an Antiseptic, which is defined as “tending to inhibit the growth and production of microorganisms” as stated by Mosby’s Pocket Dictionary of Medicine, Nursing and Allied Health. (pg. 90). Antiseptics can also be used on living things, such as humans. (Lab Manual, pg.245)…
But before antibiotics are given, they first drain the wound and remove infected tissues to prevent the spreading of infection (Carlisle 2014). The mechanism of action of the drug, penicillin G, is during active multiplication the synthesis of cell wall multiplication outcomes in bactericidal activity against susceptible…
Because of its activity against staphylococcus, Fleming’s penicillin was one of the compounds chosen for study. The first step toward isolating penicillin came in March 1940; in May 1940, Howard Florey analyzed the chemo-therapeutic effects of penicillin by treating mice infected with Streptomyces. The mice…
Most of the many inventions from World War II are still in use today. Many lives were forever changed because of the new ideas brought to us during this time period. During World War II, many new inventions and innovations were created that impacted America forever. Many famous and important inventors created their most well-known creations during World War II. Inventions such as penicillin, the atomic bomb, and the microwave are only very few of the inventions that the mastermind inventors created during World War II.…
Researchers at Oxford were working on the purification of penicillin and had turned the raw substance into a life saving drug. The continued research of penicillin made increased amounts of refined product to be produced. Making 500 litres a week, the researchers had started to refine penicillin for clinical trials. The animal experimentation…
Thesis statement Penicillin was the first antibiotic created. It helped fight the spread of disease and infections saving millions of lives. body.…
Antibiotic is a medicine that inhibits the growth of or destroys microorganisms. April 20th our class was assigned to do experiment. First step, Dr.Okeke went through the lab rule with our class. Second, our class had to get in groups of 6.…
The class of drugs used in these treatments are mostly third generation cephalosporins (PHAC,2011). Cephalosporins of this generation are used because it is more effective against the gram-negative Neisseria gonorrheae than its predecessors. These drugs include cephalexin (Keflex), ceftriaxone (Rocephin), ceftizoxime, cefoxitin, and cefotaxime. These antibiotics cause cellwall damage and lysis in gram-negative bacteria (Talaro,). Macrolides such as azithromycin and Tetracyclines such as doxycycline are sometimes used in conjuction with cephalosporins.…
After the incubation period, the agar containing the antibiotic testing was taken out and if the microbe reacted with the antibiotic, a circle or clearing would appear around the disk containing the antibiotic. The diameter of this circle was then measured and compared with a table found on page 95 of the Microbiology Lab Manual to understand the antibiotics resistance, intermediate and sensitive levels, as they differ for each antibiotic. The numbers on the table in the Microbiology Lab Manual represented whether the microbe was resistant, shown in the light blue color on the graph, intermediate, shown in purple, or sensitive to the antibiotic, shown in the periwinkle color. As shown in figure 1 above, indicated with a yellow line, each antibiotic tested on unknown microbe #7 turned out to be sensitive. The diameters of the cleared out areas were vancomycin: 21mm, erythromycin:…
All people have their own problems, some more drastic then others. A person may have poor eyesight, another may have muscle problems. Now, what if you have a bacteria infection; and wish to get rid of it? Then Tetracycline is the drug for you to be interested in. Tetracycline is a drug focused on greatly reducing the bacteria in an area of the body.…
For more than 70 years, antibiotics have been used to treat bacterial infections of the body. The first appearance of this life changing medicine, was in the 1940’s on the battlefield. This medicine was named penicillin, the drug saved many from the brink of death, by fighting bacterial diseases; from then on antibiotics changed the face of medicine. Infection was no longer an impregnable wall that had to be broken down before the real treatment could begin, infections could be treated on site, at moments notice. As time passed, the world became co-dependent on the use of antibiotics to treat all of the body 's infections, and was repeatedly misused.…
