All of the following are methods intracellular pathogens can use to survive inside a host cell EXCEPT create a capsule. Escape the phagosome. survive in the phagolysosome. prevent phagosome-lysosome fusion.

Which of the following shows the highest phagocytic activity? NK cells Pmns involved in ADCC Tc cells Macrophages involved with a parasitic infection None of the above

By what means does a phagocyte destroy a bacterium that it has ingested?

Attenuated agents may induce immunity after a single dose may cause disease in immunocompromised (sick) individuals multiply in the body may revert or mutate to disease-causing strains all of the above

Which of the following is an example of a pathogen-associated molecular pattern that might be sensed by a Toll-like receptor? Lipopolysaccarides from Gram-negative bacterial outer membranes All of the options listed are correct The spike proteins on the Influenza A virus A unique glycoprotein on the flagella of Trypanosoma cruzi

True/False: Neutrophils regulate the production of active cathelicidins (a class of antimicrobial peptides) by segregating the inactive propeptide from the processing enzyme that cleaves and activates it in two different types of cytoplasmic granules. These two types of granules are induced to fuse with phagosomes after ingestion of microbes, bringing the processing enzyme and the propeptide together.
