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 C) anti-phagocytic factors B) toxins D) adherence factors 15) Which of the following classes of virulence factor is absolutely needed for nearly every infection? In fact, if the organism lacks this factor, it is most likely going to be avirulent (not disease-causing). A) extracellular enzyme C) exotoxin B) adherence factor D) anti-phagocytic factor 16) Which of the following is an iron-binding protein produced by pathogens to access the body's store of iron? A) ferritin B) siderophores C) hemolysin D) transferrin

B) triggering release of interferons. C) triggering inflammation. D) triggering inflammation and release of interferons. E) both triggering inflammation and attracting phagocytes to sites of infection. 18) Which of the following statements regarding phagocyte recognition of pathogens is TRUE? A) Lectins on the surface of microbes are bound by chemokine receptors. B) MACS on the surface of microbes are detected by NOD proteins. C) TLRS in the phagocyte cytoplasmic membrane bind surface structures of microbes. D) NOD proteins on the surface of microbes are detected by TLRS. E) TLRS on the surface of microbes trigger the accumulation of opsonins. 19) Alpha and beta interferons A) produce no adverse effects in the body. B) are produced by infected fibroblasts and macrophages. C) produce active antiviral proteins (AVPS) that coat the surface of healthy cells and prevent the attachment of pathogenic viruses. D) help protect virus-infected cells from the effects of the pathogen. E) protect the cells that secrete them from being invaded by a virus. 20) Which of the following white blood cells does NOT perform phagocytosis of bacteria? A) macrophages B) lymphocytes C) eosinophils D) neutrophils
