17. Pertussis is two diseases
18. B. pertussis is a strict human pathogen
19. Infection causes suboptimal immune responses
20. Virulence factors of B. pertussis - toxins
21. Pertussis toxin
22. Adenylate cyclase toxin (ACT)
23. ACT inhibits neutrophil phagocytosis
24. Dermonecrotic toxin
25. Tracheal cytotoxin
26. Virulence factors of B. pertussis - adhesins

30. Vaccine induced antibody-mediated immunity
31. Anti-toxin antibodies
32. Anti-adherence antibodies
33. Bactericidal antibodies
34. Opsono-phagocytosis
35. Phagocytosis assay
36. Neutrophil phagocytosis
37. Neutralizing Ab to ACT promote phagocytosis
38. Opsono-phagocytosis activity after vaccination
39. Vaccine does not enhance phagocytosis
40. Opsono-phagocytosis activity after infection
41. Phagocytosis with convalescent serum
42. ACT blocks phagocytosis in WT
43. Phagocytosis with serum depleted for Ab to FHA
44. FHA is both bound to the bacteria and secreted
45. Ab to FHA delivers ACT to neutrophils
