Pathogenicity
Infection and Transmission
The infections are generated by the pathogenic organisms present in the environment. They maintain the capacity to invade a host body and establish colonies. A disease caused by such infectious agents is called a communicable disease or transmissible disease. These diseases spread through diverse means including blood, food, water, air, or vectors.

Step by step
Solved in 2 steps
- What is a disease progress curve? Draw an example disease progress curve for a monocyclic disease and a polycyclic disease on the same set of axes. Label each curve.What is a vector? What is a zoonotic pathogen? Example? (ha!)What is disease causation theory? Define personalistic and naturalistic disease causation using films and/or readings.
- What is the difference between preventions treatments and cures?Select all of the following that applies to the tradeoff between transmission and virulence that applies to many diseases. a) The tradeoff between transmission and virulence means that diseases always evolve to become more virulent. b) If greater virulence limits transmission, that disease will likely evolve to become less virulent than it could be. c) While making more copies of itself can increase the likelihood of transmission occurring, too much replication of the disease can make the host so sick it won't leave the house and spread the disease. d) A strain of a disease that replicates enough to be transmitted, but not so much that the host gets too sick to move, will be favored by natural selection over strains that either make the host too sick or do not replicate enough to be transmitted. e) If a disease can spread without making its host sick (e.g. when the host is asymptomatic), then the tradeoff between transmission and virulence…Compare parasitism and mutualism for the two factors (A and B) below.
