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.
In agriculture, what are the six steps involved in the disease cycle? Describe what occurs at each step.
Step by step
Solved in 2 steps
- What characteristics deem a disease complex or multifactorial? Briefly describe three examples of multifactorial diseases in humans.For any diseases caused by a virus: What is the name of the disease? What bacterium or virus or plasmodium causes the disease? Name the vector responsible for the transmission. What is the life cycle of the pathogen? How is the pathogen transmitted? What effect does the pathogen have on the host? How can spread of the disease to others be controlled?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…
- What are the 4 mode types of disease? Explain eachHow will the following factors contribute to the ability ofbacteria to invade the host?A. Antigenic variationB. Penetration into the Host cell cytoskeleton34) Which of the following fungal diseases involves an intracellular parasite that partially disables macrophages, allowing for spread beyond the lungs. A) Coccidioidomycosis C) Pneumocystis B) Blastomycosis D) Histoplasmosis 35) Of the following genetic material types seen in viruses, which genetic material type leads to rapid, almost immediate production of viral proteins, followed closely by replication of the genome leading to rapid synthesis of new viruses, which tends to overwhelm the host, as exemplified in a viral disease which causes more than 200,000 deaths of children worldwide each year. A) negative (-) strand single-stranded RNA B) double-stranded RNA D) positive (+) strand single-stranded RNA C) single-stranded DNA
- 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.

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)What is a Black Plague?
