Exotoxins are proteins released during bacterial growth. The other options are not true of exotoxins.
Exotoxins are contained in cell walls of gram-negative bacteria.
Endogenous pyrogens acting directly on the hypothalamus.
The primary cellular targets for HIV include CD4+ Th cells, macrophages, and NK cells. The other options are not the primary target cells of HIV.
The host defense against fungal infection includes the fungistatic properties of neutrophils and macrophages. T lymphocytes are crucial in limiting the extent of infection and producing cytokines to further activate macrophages. The other options are not true of fungal infections.
From the perspective of the microorganisms that cause disease, the infectious process undergoes four separate stages of progression: (1) colonization, (2) invasion, (3) multiplication, and (4) spread.
Invasion is the direct confrontation with an individual's primary defense mechanisms against only bacteria, which include the complement system, antibodies, and phagocytes, such as neutrophils and macrophages.
