Question
Chapter 11.2, Problem 11AYP
Summary Introduction
To determine:
A definition of virulence factors.
Concept introduction:
Microorganisms that cause disease are termed as pathogens or the infectious causative agents. When a pathogen invades the tissue of an individual it will lead to create infections. Infectious agent which has the ability to cause disease is called pathogenicity and the rate to which an infectious agent is pathogenic is termed as virulence.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
