By Movement Bacilli-use or "tail"A. Antibiotics, such as gentamicin, are used in media to prevent growth of susceptible microbes. Is gentamicin media a selective, differential or enrichment media? B. Sorbitol is a sugar alcohol that all Escherichia bacteria can normally ferment into an acidic waste compound. This acidic end product is detected by including a pH indicator in the agar and noticing a color change. The strain of Escherichia that is a common food pathogen, E. coli O157:H7, however can not ferment sorbitol. It will grow similar to other E. coli, but not change the agar color. Is sorbitol in nutrient agar a selective, differential or enrichment media?Biofilms are often formed on artificial surfaces in the human body. During medical procedures, when artificial joints, intravenous catheters, urinary catheters are placed and injections are made, commensals/mutualists may be introduced into new sites in the body and there they may form biofilms. Which statement below is NOT a reason to explain why such bacteria living in biofilms are so difficult to eliminate? O layers of biofilm prevent phagocytes from killing bacteria O layers of biofilm acts a a diffusion barrier against antibiotics O biofilm stimulates bacteria to grow continually in the log/exponential phase of growth O layers of biofilm acts a a diffusion barrier against antibodies/immunoglobulins O bacteria often in stationary phase of growth

Which of the following terms is the most accurate for describing the bacterium? A. A Chemoorganoheterotroph B. A Phototroph C. A Halotroph D. A ChemolithoautotrophYou have two organisms A and B. One is an obligate aerobe and the other is an obligate anaerobe. You have 2 Nutrient Agar Plate Media that these organisms can grow on. How can you differentiare which organism is aerobic and which is anaerobic.
- Which of the following is NOT correctly matched? A. Halophile – microbe that can grow in an environment with high osmotic pressure (e.g., salt) B. None of the other four answers (all are correctly matched) C. Agar – complex polysaccharide from seaweed used as a solidifying agent in culture media D. Colony – a population of microbial cells arising from a single cell or spore or from a group of attached cells E. Capnophile – microbe requiring an elevated molecular oxygen (O2) environment for optimal growthThe first step for directly linking a microbe to a specific disease according to Koch's postulates is to O isolate microbes from the blood of healthy animals. obtain a sample of blood or other body fluid from a diseased animal. O culture the blood or other body fluid from a discased animal using nutrient medium. O inject a sample of blood or other body fluid from a diseased animal into a healthy animal. O compare the blood of a sick animal to blood obtained from a healthy animal.1. How is UV radiation a good type of control mechanism against microbial growth? Please explain what happens to the microbe and effects this control causes. 2. Suppose you do the Kirby-Bauer test on a hypothetical Staphylococcus species with penicillin and tetracycline. You record diameters of 20mm for tetracycline and 24mm for penicillin. Which antibiotic is most effective against this bacterium and why? Please explain and interpret these results. 3. Please provide the scientific name of your microbe that was used in the UV experiment (i.e. S. aureus). Compare your plates and interpret/analyze your results. Please discuss your findings and any patterns you were able to gather. 4.
