2. aureus: a common bacterium found in the upper respiratory tract.
4. a single stranded RNA has an envelope and extremely variable.
6. toxin: responsible for red rushes effect on body.
7. Pyogenes: cause by gram positive bacteria, most serious bacterial pharyngitis.
10. pyogenes: produces exotoxin which displays B hemolysis on beta.
12. Shift: more drastic results from RNA exchange between different ifleunza viruses.
13. a gram negative bacterium that causes sore throat that can potentially lead to syndrome.
14. TB: about 10 bacterial cells asymptomatic bacteria multiply inside macrophages.
15. drift: less drastic it results from mutation of glycoproteins,

1. this is viral, usually a typical increase during winter months, spreads vy aerosols and droplets entering respiratory system.
3. human disease mostly in lungs have secondary and primary cases.
5. Otitis: an ear infection caused by viral infection in the upper respiratory tract.
8. Fever: caused by pyogenesis strep, where bicuspid valve narrowed in the left side of the heart.
9. treatment for strep pyogenes it targets peptidoglycan specifically.
11. in the lower respiratory tract, it's a condition of lungs where fluid fills alveoli.
