Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be normal and beneficial but also be pathogenic?
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)
14) When considering virulence factors, which class of virulence factor would be most likely to increase the severity of
disease caused by the pathogen possessing the virulence factor, due to this class of virulence factor most likely causing
the death of cells?
A) extracellular enzymes
