Understand the term 'intracellular pathogenesis': It refers to the process by which pathogens, such as bacteria or viruses, invade and establish an infection within the host's cells.
Identify the key components of intracellular pathogenesis: This includes the ability of the pathogen to enter the host cell, survive, and replicate within it, often evading the host's immune responses.
Differentiate between intracellular and extracellular pathogens: Intracellular pathogens live and replicate inside host cells, while extracellular pathogens do so outside host cells.
Consider the mechanisms used by pathogens to invade host cells: These can include the secretion of enzymes that break down cell membranes or the use of specialized structures to penetrate the cell.
Evaluate the host's intracellular defense mechanisms: Host cells have various strategies to prevent infection, such as autophagy, production of reactive oxygen species, and activation of immune signaling pathways.
