Summary Introduction

Introduction:

Salmonella is the etiological agent responsible for the outbreak of diarrheal illness.

Case summary:

On April 2, 2130 students and employees of a public school developed diarrheal illness. The cafeteria served chicken on that day. Part of the chicken was placed in water-filled pans and cooked in an oven for 2 hours at a dial setting of 177º C on April 1. After turning off the oven, the chicken was left overnight in the warm oven. The remainder of the chicken was cooked for 2 hours in a steam cooker and then left in the device overnight at the lowest possible setting (43º C). From 32 patients, two serotypes of a gram-negative, cytochrome oxidase-negative, lactose-negative rods were isolated.

Characters of the case:

  • patients
  • Chicken
  • Gram-negative, cytochrome oxidase-negative, lactose-negative, rod-shaped bacteria

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
