Question 5

N. gonorrheae Diseases

Answer 5

-Virulence factors: Pili, outer-membrane porin protein, capsule, endotoxin, IgA
protease and protein II (block bactericidal effect of host IgG)
NOT MICROBIOTA
-DISEASES: gonorrhea, conjunctivitis or ophthalmia neonatorum, oropharyngitis, gonococcemia, septic arthritis, endocarditis, and pericarditis
-CAN CAUSE: : Pelvic inflammatory diseases, ectopic pregnancy, sterility, FitzHugh-Curtis syndrome, epididymitis

Question 6

N. meningitidis Diseases

Answer 6

• Virulence factors: Polysaccharide capsule, pili, outer-membrane porin proteins,
  endotoxin and IgA protease
  -Normal microbiota in the oral/pharangitis/nasal mucus membrance
  -DISEASES: acute, purulent meningitis associated with meningococcemia.
  Bacteremia leads to thrombocytopenia, DIC, and shock.
