Different strains of Streptococcus pyogenes have different virulence factors, giving these microbes much versatility. Virulence factors include which of the following? Choose one or more: A.A capsule that, when thick, will help the organism avoid phagocytosis by macrophages B.A cell wall containing lipoteichoic acid, thought to facilitate adherence to pharyngeal epithelial cells C.Enzymes that lyse blood cells (streptolysins) D.The production of several endotoxins called streptococcal pyogenic endotoxins (SPEs)

If so, what causes the species to become pathogenic? Construct at table to compare and contrast the 5 steps of microbial pathogenesis. How does extracellular growth differ from intracellular growth? Diagram the 5 step pathogenesis cycle for coli O157:H7, an extracellular, intestinal pathogen acquired by consuming contaminated food/water. Be sure to include the role of exoenzymes and the Shiga exotoxin in your diagram. (2 points) Explain the pathogenesis of Listeria monocytogenes. Be sure to include temperature regulation, intracellular growth, and at risk groups in your discussion.
