Question options: blood clot cytochrome hemolysin histamine siderophore tautomer Which of the following statements is FALSE? Question options: acute inflammation develops fairly quickly chronic inflammation is harmful the permeability of small veins in an inflamed area increases the warmth in an inflamed area is a result of additional heat transported to the area by blood vasodilation increases blood flow to an area during an inflammatory response all these statements are TRUEWhich of the following involves pseudopods? adherence of phagocytes to pathogens chemotaxis opsonization extracellular killing a & b
- The attachment of a pathogen to host cells requires that Group of answer choices pathogen adhesins bind specifically to host glycoproteins. host antibodies attach to the pathogen adhesins. the resident microbiota be unbalanced. pathogen toxins enter the cell by endocytosis.Which of the following is an example of a pathogen-associated molecular pattern that might be sensed by a Toll-like receptor? Lipopolysaccarides from Gram-negative bacterial outer membranes All of the options listed are correct The spike proteins on the Influenza A virus A unique glycoprotein on the flagella of Trypanosoma cruziChemicals released to complete extracellular killing include __________. (Select all that apply) IgA perforin iron binding molecule lysozyme granzyme histamine
- The material which is the result of the battle between macrophages and invading microbes is called ___. It is a yellow or greenish semi-liquid.Which of the following does not belong to the group? Antimicrobial proteins Resident microflora Inflammatory response PhagocytesA white blood cell has pathogen recognition proteins embedded in its plasma membrane. Initially, the the pathogen recognition proteins are spread over the whole surface of the white blood cell. The white blood cell comes into contact with a bacterial cell. Some of the pathogen recognition proteins bind to the lipoteichoic acid molecules on the surface of the bacterial cell. As time goes on, more and more of the pathogen recognition proteins bind to the lipoteichoic acid molecules on the bacterial cell surface. The white blood cell membrane at the point of contact between these 2 cells now contains a dense cluster pathogen recognition proteins. How is it possible for the pathogen recognition proteins to go from being equally distributed on the white blood cell surface to being clustered at the point of contact?
- The ability of some microbes, such as Trypanosoma or Giardia to alter their surface molecules and evade destruction by the host's antibodies is called: cytopathic effect lysogenic conversion antigenic variationWhich of these pairs are mismatched? a. cytosol: intracellular pathogen b. surface of epithelium: extracellular pathogen c. nucleus: intracellular pathogen d. lymph: intracellular pathogenPathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexes
