Multiple Choice

Which of the following answers is not a mechanism pathogen use to survive within a phagocytic host cell?

Withstanding the digestive and hydrolytic enzymes of the phagolysosome.

Secreting digestive enzymes to lyse the phagocytic cells from the inside.

Forming pores in the phagosomal membrane and escaping the phagosome.

Creating proteins which blocks the fusion of the phagosome and lysosome.

Verified step by step guidance

Understand the context: Pathogens have developed various mechanisms to survive within phagocytic host cells, which are part of the immune system designed to engulf and destroy pathogens.

Identify the mechanisms: Review the mechanisms listed in the problem that pathogens use to survive within phagocytic cells. These include withstanding enzymes, forming pores to escape, and blocking fusion of phagosome and lysosome.

Analyze each mechanism: Consider how each mechanism helps the pathogen survive. For example, withstanding enzymes allows survival in harsh conditions, forming pores enables escape, and blocking fusion prevents digestion.

Evaluate the incorrect mechanism: The problem asks for the mechanism that is not used by pathogens. Secreting digestive enzymes to lyse the phagocytic cells from the inside is not a typical survival strategy for pathogens within phagocytic cells.

Conclude the analysis: Based on the evaluation, identify the mechanism that does not fit the typical strategies used by pathogens to survive within phagocytic host cells.
