- Mycoplasmas are bacteria that lack cell walls. On the basis of this structural feature, which statement concerning mycoplasmas should be true? They are gram-negative. They are subject to lysis in hypotonic conditions. They lack a cell membrane as well. They should contain less cellulose than do bacteria that possess cell walls. They possess typical prokaryotic flagella.Pseudomonas is a gram-negative rod-shaped bacterium, sometimes inhabits the intestinal tract, and considered an important cause of urinary tract infection and sepsis, however, it is not a member of family Enterobacteriaceae. Discus this statement, keep your response within 80-100 characters limit.*clostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.
- you grew streak plates of Clostridium sporogenes under both aerobic and anaerobic conditions. Which plates showed bacterial growth, and what does the zone around the metronidazole disc represent? Additionally, explain what types of bacterial growth metronidazole affects and why.Explain the role of pylori in the pathogenesis of peptic ulcers. Which populations are most susceptible to peptic ulcers? Is H. pylori normal flora? If so, what causes the species to become pathogenic? Construct at table to compare and contrast the 5 steps of microbial pathogenesis. How does extracellular growth differ from intracellular growth? Diagram the 5 step pathogenesis cycle for coli O157:H7, an extracellular, intestinal pathogen acquired by consuming contaminated food/water. Be sure to include the role of exoenzymes and the Shiga exotoxin in your diagram. (2 points) Explain the pathogenesis of Listeria monocytogenes. Be sure to include temperature regulation, intracellular growth, and at risk groups in your discussion.hich of the following can produce inactive endospore-like bodies that are infectious to human epithelial cells? Rickettsia Echrlichia Bartonella Chlamydia Caulobacter
- Bacteria of the genus Mycoplasma are distinguished from other bacterial cells by 1) cell walls composed solely of amino acids. O 2) the absence of a cytoplasmic membrane. O 3) the absence of a cell wall. O 4) Have large capsules. 5) the presence of mycolic acid in their cell walls.Once these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells. Compare Inhalation anthrax (Bacillus anthracis) to Tetanus (Clostridium tetani). Besides endospores used in transmission, what is a simple explanation to help explain how each microbe survives and grows in each location?Many antibiotics used in modern medicine are compounds made by fungi that inhibit bacterial protein synthesis. Describe the specific effect of the following antimicrobial drugs: (i) Chloramphenicol (ii) Rifamycin
- Most medically useful antibiotics interfere with either peptidoglycan synthesis or ribosome function. Why would the cell membrane be a poor target for antimicrobial medication?Name two methods of control of growth for Mycobacterium tuberculosis pathogen in a patient with the disease and when confronted with the pathogen outside of the host. Be careful to specify if it is a physical method or a chemical method (check lecture to differentiate these two). Control of growth means how would you deal with an infection related to a person as well as how would you minimize the presence of the bacteria on a surface or object.In the diagram below, identify the structures of a cyanobacterial cell based on the following descriptions: a) Outer cellular covering which includes: Mucilaginous layer – outermost layer covering the cell wall; protects the cell from harmful factors of the environment Cell wall – found just below the mucilaginous layer; 2 or 3-layered, the inner layer lies in between the outer wall layer and plasma membrane; the outer layer is made of peptidoglycan Innermost plasma membrane – selectively permeable membrane enclosing the cytoplasm b) Cytoplasm – found below the plasma membrane; the protoplasm which contains structures of different shapes and functions. Lamellae, which contain pigments such as chlorophylls, carotenes, xanthophylls, phycoerythrin and phycocyanin, are located in the peripheral region of cytoplasm. Ribosomes may also be found scattered in the cytoplasm. c) Nucleic material – the nucleoplasm that is centrally located in the cell and contains chromatin in the form…
