  1. Upper Respiratory Tract
    • Streptococcal Diseases
    • Diphtheria
    • Whooping Cough
    • Meningococcal Meningitis
    • Haemophilus Meningitis
  2. Streptococcal Diseases
    • Large group of encapsulated Gram+’s
    • Causewell-known diseases:
    • “Strepthroat”
    • Otitismedia
    • Scarlet fever – strep throat + rash
    • Rheumatic fever – cardiac sequelae
    • Necrotizing fasciitis
    • Streptococcus pyogenes
    • Best known for hemolytic ability
  3. Alpha hemolytic
    partial destruction of red blood cells
  4. Beta hemolytic
    total destruction of RBC’s
  5. Diphtheria
    • Corynebacterium
    • diphtheriae
    • Gram + bacillus
    • Generates potent exotoxin
    • Most distinctive symptom
    • “pseudomembrane”
    • accumulation of dead tissue + white blood cells
    • asphyxiation
  6. Whooping Cough
    • Bordetella pertussis
    • Gram - rod
    • Dangerous
    • childhood disease
    • Distinctive cough
  7. Meningococcal Meningitis
    • Neisseria meningitides : “meningococcus”
    • Gram – encapsulated diplococcus
    • Meningococcemia
    • rapidly fatal septicemia
  8. Haemophilus Meningitis
    • Haemophilus influenzae
    • Childhood disease : 6 mos to 2 yrs
  9. Lower Respiratory Tract
    • Tuberculosis
    • Pneumococcal Pneumonia
    • Primary Atypical Pneumonia
    • Klebsiella Pneumonia
  10. Tuberculosis
    • Mycobacterium tuberculosis
    • Problem again because of AIDS
  11. Pneumococcal Pneumonia
    • Streptococcus pneumoniae
    • “pneumococcus”
    • Gram + encapsulated diplococcus
    • opportunist
    • Strep pneumoniae serious cause of meningitis
  12. Pneumonia
    microbial disease of the bronchial tubes & lungs
  13. Lobar pneumonia
    involvement of an entire lobe of lung
  14. Double pneumonia
    both left and right lungs involved
  15. Bronchopneumonia
    scattered patches ofinfection in respiratory passage ways
  16. Primary Atypical Pneumonia
    • Mycoplasma pneumoniae
    • Pleomorphic,no Gram rx “Walkingpneumonia”
    • “Atypical”= not Strep pneumoniae viral-like symptoms
  17. Klebsiella Pneumonia
    • Klebsiella pneumoniae
    • Gram – encapsulated rod
    • Dangerous misdiagnosis
    • more aggressive than Strep
    • not susceptible to penicillin
