  • Q4
    How is a reemerging pathogen different from an emerging pathogen?
    C) A reemerging pathogen is an infectious agent that was under control due to prevention or treatment strategies but is now resurfacing.
    A) A reemerging pathogen is an infectious bacterial infection that manifests once every few months but goes away without treatment and only blisters the skin in another few months.
    E) A reemerging pathogen is an infectious agent that went away when the patient was taking antibiotics but quickly returned when the patient stopped taking the antibiotics.
    B) A reemerging pathogen is an infectious helminth that was detected in one location of the body but receded and emerged from a second location.
    D) A reemerging pathogen is an infectious agent that was identified previously in one location but is now emerging in a new separate location.

  • Q5
    Why are Koch's postulates important to microbiology?
    A) They demonstrate the preferred route of infection for a particular disease.
    C) They enable us to characterize the species of the infectious disease whether it is a bacteria, virus, or fungi.
    B) They provide a way to select the most effective concentration of antibiotic to use for a patient.
    D) They allow us to identify the causative pathogens of many infectious diseases.
    E) They explain how a particular disease produces specified signs in a patient.

  • Q12
    *** If you had to choose to be either a chronic carrier or an asymptomatic carrier, which would you choose and why?
