Concept explainers

Immune Disorders

The collaboration between the cells and proteins that work together as a defense system against infection comprises the immune system.Each of them performs a variety of tasks to recognize and/or react against a foreign body.

Question

Microbes possess many different strategies to help them cause disease called virulence factors. Explain how two virulence factors work. For each virulence factor state the name of the mechanism, explain how it works and what advantage it gives the organism that helps it cause disease.

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)
For each of the following: Cyanobacteria, Coronavirus, Chytrids, Ciliates, and Chronic wasting disease. Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.
