What bacteria cause laryngitis, tracheitis, & epiglottitis?
Group A Strep (S. pyogenes)
Haemophilus Influenza B
What causes bacterial bronchitis?
Outline the four stages of pertussis infection.
1) Incubation= 7-10 days asymptomatic
2) Catarrhal= 1-2 weeks of "common cold"
3) Paroxysmal= 2-4 weeks of whooping cough & post-tussive emesis
4) Convalescent= 3-4 weeks of improved cough but severe complications--pneumonia, seizures, encephalopathy
What bacteria typically cause bacterial influenza associated pneumonia?
Aside from being the only DNA virus to cause the common cold, what else is unqiue about the adenovirus?
Contains adenoviral fiber proteins that are used for attachment & are toxic to cells
