Explain the possible mechanisms by which Pseudomonas aeruginosa invades and creates biofilms through a quorum sensing.
74) Pseudomonas aeruginosa is one of the most notorio mechanisms does this bacteria use to evade antimicrobials? A) target alterations B) drug inactivation C) efflux pumps that pump the drugs out of the bacterial cell D) reduced permeability E) This bacteria uses all of the possible ways to evade antimicrobials, which is why it is so good at it. usly resistant pathogens. Which of the following
name this bacteria and explain why possible correct answers are: •Pseudomonas aeruginosa • proteus vulgaris • eschericia coli • enterobacter aerogenes •shigella flexneri •citrobacter freundii 0 , Սալիվար (վ հացիվիլիկիայի We were unable to transcribe this image

QUESTION 40 Which best describes bacterial quorum sensing? A system that allows bacteria to transfer virulence factors from one bacterium to another by horizontal gene transfer. A system that allows bacteria to sense their own population density by communicating with each other by way of secreted chemical factors and behaving as a population rather than as individual bacteria. A system that enables bacteria to directly injecting bacterial effector molecules into the cytoplasm of the host cell in order to alter...
Explain how a superantigen toxin non-specifically stimulates T cells. Why does non-specific stimulation of T cells make a person sick? Explain the molecular mechanisms by which quorum sensing regulates TSST-1 expression. How do superantigens promote immune evasion? Describe impacts on B cells and T cells Why is toxic shock syndrome associated with high absorbency tampons and menstruation?
