Bacteria Lab Report
Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report, we discover the most effective disinfectant that would work best in killing the harmful bacterial strain, Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly with my results but Lysol was only 4mm more sustainable then Windex. Lysol with the biggest zone of inhibition of 28mm allowing this disinfectant to kill the most Bacillus subtilis bacteria. Still, Lysol was succeeded to work, but overuse or misuse of antibiotics and also not compelling a prescribed course can allow antibiotic resistance to spread. "Everything is covered in invisible ecosystems made of tiny life forms." -Jessica Green. These tiny single-called organisms that live almost everywhere contain two types of DNA, plasmid and chromosomal. The chromosomal DNA carries most of the genetic information. Bacteria can be good by helping you with digestion, …show more content…
I measured the spread of the bacteria by testing how resister the bacterial strain is to the antibiotic through the Kirby Bauer antibiotic testing. KB testing or disc diffusion antibiotic sensitivity testing was measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. Windex is a disinfectant that rejects 99.99% of destructive bacteria and the zone of the inhibition tested did fighting of bacteria proving that this kind of bacteria was not antibiotic resistance. One mistake made was using ethanol as one of the disinfectant and also having better control over the technique of the quadrants by following the aseptic isolating techniques

    Microbiology Unknowns Lab Report

    In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter they will use the sugars to make ATP. If the bacteria is a fermenter of lactose/sucrose the EMB plate we used will “clearly differentiate between the colonies of lactose fermenting and non-fermenting microbes. In the same medium sucrose was also included to differentiate between coliforms that were able to ferment sucrose more rapidly than those that were unable to ferment sucrose” (Cheeptham & Lal, 2007).…

    Unknown Bacteria Lab Report

    This was compleated by growing the bacteria on a petri dish with agar, gram staining, then examning under a microscope. The bacteria identified was M. Roseus and B. Megaterium. The identity of these bacteria was mostly determined by the positve gram stain results and the shape they where under the microscope. Both of these bacteria where identified as gram positive (as shown in the table previously). This was determined beause of the nonexistant fatty layer in the cell’s cell wall that trapped the purple crystal violate. The second big thing that identified these bacteria was the shape you could see under the microscope. While looking under the oil immersion lense, the B. Megaterium was shaped as a rod, and the M. Roseus was shaped as a circle. The diference between these two was, the rod was a much longer and skinnier shape compared to the circle whitch was smaller and more round than the rod was. The error in this experiment was that during gramstaining the second bacteria. I was able to identify three different bacteria. One was small purple circles (the M. Roseus), another was purple rods (B. Megaterium), and the last one was small pink circles that was not identified. In this lab, one of the problems that was encountered was the bacterias would not grow. Although this was probably because failing to cool the loop while streakig, this was still one one of the main problems encountered. Another issue that was…

    Control by Antibiotics and Antiseptics Lab Report

    The fact that each bacterial species, and even some of their respective strains, responds uniquely to a given antimicrobial makes it necessary to have methods, which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By utilizing the Kirby-Bauer method, researchers and clinicians are able to determine the susceptibility of given microorganisms to different antibiotics and antimicrobials. While antibiotics specifically target bacteria, antimicrobials cast a wide net, nonspecifically targeting microorganisms and viruses. During this lab, we tested the effects of both antimicrobials and antibiotics on different bacterial cultures. By creating different lawns of bacteria and placing on each of them disks soaked in different antibiotics and antimicrobials, we were able to observe the susceptibility of the differing bacteria to several agents. This process that we practiced is the Kirby-Bauer method. As stated before, antibiotics and antimicrobials serve differing purposes. Antibiotics are substances, usually in the form of medication, that destroy bacteria or inhibit the growth of bacteria. On the other hand, antimicrobials act in destroying or inhibiting the growth of all microorganisms. One type of antimicrobial is an antiseptic, which acts to reduce the presence of microorganisms without harming living animal tissue (El-Mayas, 2013). It is important to note that while we were able to measure the susceptibility of these agents, we cannot conclude that resistance is present because further investigations would have to be conducted to determine if the microorganism has developed a metabolic capability to withstand the agent’s mechanisms and effects (Maxwell, 2013).…

    Risk Assessment for Antibiotics

    The antibiotic that was the most effective was Streptomycin. This was due to Streptomycin being an antibiotic that works on gram negative bacteria. Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol whereas Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. The bacteria we used were E-coli that are a gram negative bacteria and the only antibiotic out of Penicillin and Streptomycin that will work is Streptomycin. Penicillin is also effective antibiotic but it will only work on bacteria that Is gram positive because it is an antibiotic that has been designed in order to just work on gram positive because the antibiotic itself is gram positive. We know that Streptomycin was most effect due to their being a bigger zone of inhibition. Streptomycin was also the most effective because it affects the protein synthesis whereas Penicillin affects bacterial cell wall synthesis. Penicillin lengthens the bacteria but it cannot divide it.…

    Antimicrobial Lab Report

    In this lab, chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar, which allows the agents to diffuse freely, and a growth medium is incubated over its’ surface. During incubation, the chemotherapeutic agents move from levels of high concentration, to low levels of concentration. To be effective, the agent must inhibit bacteria growth and measurements that were made by the zones of inhibition around the Petri disk. Zone size is affected by diffusion rate of the antibiotic and growth rate of the organism. The Minimum Inhibitory Concentration (MIC) is represented by the concentration of chemotherapeutic that stands at the edge of the zone of inhibition. The MIC is determined by comparing the zone of inhibition with the *Table 1 MIC values. The cultures assigned were Staphylococcus aureus (gram positive…

    Kirby Bauer Antibiotic Filter Paper

    Today you will perform a frequently used procedure called the Kirby-Bauer Antimicrobial Susceptibility test (disc diffusion technique). Each group will inoculate his/her own plate of Mueller-Hinton agar with an assigned culture. To that inoculated plate, you will then aseptically add sterile filter paper discs (using a disc dispenser), which contain a known concentration of antibiotics. As soon as the antibiotic discs touch the agar, the antibiotic will begin to diffuse into the surrounding agar. During incubation the bacteria you inoculated onto the agar…

    Fighting Bacterial Growth

    The purpose of this lab was to determine the effectiveness of antiseptics, disinfectants, and antibiotics on bacteria. The hypothesis was that if bleach was used, it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro, erythromycin, and tetracycline for the antibiotics. All of these chemicals were used on the bacteria M. luteus. Two Petri dishes were covered in the bacteria and split into four quadrants, in which each had a disc containing one of the chemicals stated above. One quadrant was left alone with no chemicals for the control group. The dishes were then left for the bacteria to grow, and once obtained again it was obvious that some of the bacteria was killed by the chemicals. In individual data, there was a zone of inhibition of 3mm in the antibacterial soap; 10mm in the Scope mouthwash; 2mm in the bleach; no zone of inhibition around the ammonia; 10mm in both the erythromycin and the tetracycline, and 15mm for the Cipro. The average length of the halo of inhibition in antiseptics was 8 mm in the E. coli, and 6 mm in the M. luteus. The average length of the halo of inhibition in the disinfectants was 12mm and 11mm respectively. For the antibiotics, it was 7mm and 9mm respectively. The data represented the hypothesis because for both the E. coli and the M. luteus, the largest zone of inhibition was in the disinfectant; and more specifically, the averages were 28mm in the E. coli and 18mm in the M. luteus in the bleach. In some Petri dishes, the bleach also killed bacteria in the other quadrants, indicating that it killed a lot of bacteria. This also affected some measurements for the other chemicals, because the zone of inhibition for the other chemicals around the bleach could have been caused by the bleach instead of the other chemical.…

    Lab Report: Antibiotic Evaluation by the Kirby-Bauer Method

    To study whether a microbial product qualifies as an effective antibiotic, a standard procedure called the Kirby-Bauer method is employed. This method, which is the procedure recommended by the US Food and Drug Administration, was devised by William Kirby and A.W. Bauer in 1966. In the current protocols involved in the Kirby-Bauer method, Mueller-Hinton standard agar is used as the medium for bacterial culture. The pH of the standard agar is 7.2 to 7.4 and it is poured exclusively to a depth of 4 mm. The medium is heavily inoculated with bacteria and paper disks containing enough of the antibiotic under study to create an optical density of 1 (the McFarland standard) are placed on top of the cultures. By examining the results of incubation in the form of a zone of inhibition around each disk after incubation, it can be determined how effective each antibiotic is against any given bacterium. A minimum inhibitory concentration can then be deduced for the given antibiotic vs. the specific bacterium tested so that appropriate dosage may be determined. Resistant bacteria cultures will show a small or no zone of inhibition if their growth is not sufficiently inhibited for the antibiotic to be a viable candidate in treating infection by…

    Antimicrobial Assay Worksheet

    This picture represents an antimicrobial agent susceptibility assay by using the disc diffusion technique. The test measures the antimicrobial activity, by determining the smallest amount of agent necessary to inhibit the growth of a specific test organism, this value is the minimum inhibitory concentration (MIC). The MIC expresses the lowest concentration of agent that completely inhibits the growth of the test organism (Madigan, Martinko, Stahl, & Clark, 2012). The areas around the disks are the zone of inhibition, which are “proportional to the amount of antimicrobial agent added to the disc, the solubility of the agent, the diffusion coefficient, and the overall effectiveness of the agent” (Madigan, Martinko, Stahl, & Clark, 2012, p. 763).…
