Students have asked these similar questions

Discuss the following virulence factors: collagenase, hemolysin, siderophore. For each, explain the molecules involved, the pathogen-host interaction, and name a species and disease associated with each factor.

Below 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)

Explain how specialized structures (e.g., spore, capsule, fimbriae, or flagella) enable a microbe to survive in a given environment or contribute to pathogenesis.
