Which bacterial gene encodes the toxin for Corynebacyterium diphtheria?
tox gene
What is a pseudomembrane?
aids in attachment to respiratory tissues
What is the incidence of diphtheria in the US? How is the disease prevented?
-100,000 children in US
-It is prevented by an acellular diptheria toxoid that has been inactivated by tx c/ formaldehyde.
Is there a vaccine for Whooping cough?
Yes, an acellular vaccine (included in DPT)
What is the normal progression of Mycobacterium tuberculosis?
Inflammation/lesions in lung tissus, causes a cellular immune response, and the growth rate is slow. Sx vary, but usually primary lesions.
What organisms can typically causes pneumonia?
Streptococcus pnuemoniae; S. aureus, H. influenzae, Klebsiella spp, E. coli, Proteus spp.
What is the most common respiratory disease caused by a fungus?
Histoplasmosis (Histoplasma capsulatum), which usually occurs worldwide and common in midwestern states.

Pneumoncystic pneumonia (PCP; Pneumocystic carinii)
What is the pathogenesis of Anthrax?
Spores inhaled, ingested by mO but are not killed, enter blood stream and produce toxin
What is the tx for Anthrax?
Ciprofloxacin
Describe the actions of the anthrax toxin
2 subunits: A, which contains the subunits Edema and Lethal Factors; and B, which is a protective antigen. At the cell surface, assembly occurs, forming holotoxin.
