- What factors determine the outcome of most host-pathogen relationships?arrow_forwardBelow are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)arrow_forwardHow is the timing of a propagated epidemic related to the incubation period of the pathogen?arrow_forward

- Which of the following statements is false?a) A disease with a long incubation period might spread extensively before an epidemic is recognized.b) A person exposed to a low dose of a pathogen might not develop disease.c) The young and the aged are more likely to develop certain diseases.d) Malnourished populations are more likely to develop certain diseases.e) Herd immunity occurs when a population does not engage in a given behavior, such as eating raw fish, that would otherwise increase their risk of disease.arrow_forwardExplain several ways that true pathogens differ from opportunistic pathogens.arrow_forwardHow epidemiology contributes to controlling disease transmission?arrow_forward
