Which of the following terms describes a disease that is caused by pathogens? * acquired infectious resistance O parasitic

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)

1, -n- is the capability of an organism to produce disease     2. A pathogen is a living organism causes disease in another living organism gains entrance into the body, usually through the skin or a body orifice must be able to adapt to a host environment and multiply all of the above

All of the following are true about the normal microbiota of humans EXCEPT: They are important for resistance against infection by pathogens They are present in large numbers in the upper respiratory tract and mouth They are present in large numbers on the skin Some are transient and others permanently colonize the host They can be found throughout the body, including all internal organs

Cytomegalovirus has the ability to move between adjacent cells: How does Cytomagalovirus contribute to the virulence of the pathogen?

Which is mismatched? 1) Secondary infection - infection acquired subsequent to a current infection O 2) Localized infection infection stays at or near the entry site O 3) Mixed infection - several agents established at infection site Focal infection - infection moving throughout the body, such as through the 4) bloodstream

Which of the pathogens in Figure 1 causes disease that cannot b cured with antibiotics? * bacterium fungus parasitic worm virus fungi viruses parasites O bacteria

During the 2015 Ebola outbreak in West Africa, Ebola aid workers like Abdul Lebbie engaged in a practice called contact tracing. These contact tracers locate and isolate (through quarantine) individuals who may have come into contact with an infected individual. Contact tracing is an attempt to reduce the RO of a disease by: reducing the infectious period reducing the transmission rate reducing the virulence increasing the infectious period O increasing the transmission rate

Is this a graph of an acute, chronic or latent disease?

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.
