Some general changes within these three factors that may cause an infectious disease to emerge include: A. changes in populations or behavior of reservoir hosts or intermediate hosts B. microbial genetic mutation and viral genetic recombination or assortment C. environmental factors such as an increase in precipitation D. all of the above E. none of the abovearrow_forward

Define personalistic and naturalistic disease causation using films and/or readings.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_forward
