Final answer:
The control of intracellular pathogens primarily depends on intact cell-mediated immunity.
Step-by-step explanation:
In the context of the immune system, the control of intracellular pathogens primarily depends on intact cell-mediated immunity. Cellular immunity, involving T lymphocytes or T cells, targets and eliminates intracellular pathogens. These T cells also play a central role in orchestrating the overall adaptive immune response.
