Size of microorganisms for them to be inhaled directly into the alveoli.

5 um(TOPNOTCH)Robbins Basic Pathology, 8th Ed p. 327

8

These microorganisms grow in contaminated food and releases powerful enterotoxins that cause food poisoning symptoms without any bacterial multiplication in the gut.

Staphylococcal strains(TOPNOTCH)Robbins Basic Pathology, 8th Ed p. 327

Bacterial surface molecules that bind to host cells.

Adhesins(TOPNOTCH)Robbins Basic Pathology, 8th Ed p. 332

Alpha toxin (lecithinase)(TOPNOTCH)Robbins Basic Pathology, 8th Ed p. 334

17

Bacterial toxins with the capacity to stimulate large populations of T lymphocytes, functionally resulting in a "cytokine storm".

High risk agents of bioterrorism which are easily disseminated and has high potential for mortality. An example is smallpox.

Category A(TOPNOTCH)

22

A distinctive form of mononuclear inflammation usually evoked by infectious agents that resist eradication, but are capable of stimulating strong T cell mediated immunity. Characterized by epitheloid cells which may fuse to form giant cells.

Granulomatous inflammation(TOPNOTCH)Robbins Basic Pathology, 8th Ed p. 335
