Which is true about a tuberculin skin test (TST): Positive TST indicates active tuberculosis (TB) infection Negative TST rules out active TB infection Positive TST indicates past exposure to TB Negative TST indicates past exposure to TB

TST tidbits TST is a screening tool to detect latent TB infection Positive TST indicates active tuberculosis (TB) infection Negative TST rules out active TB infection Positive TST indicates past exposure to TB Negative TST indicates past exposure to TB TST tidbits TST is a screening tool to detect latent TB infection 20% of patients with active TB will have negative TST results TB is diagnosed by abnormal chest radiograph and sputum specimen + AFB staining followed up by culture.

Immunoglobulin G (IgG) Immunoglobulin M (IgM) Immunoglobulin A (IgA) The primary immune response after exposure to a communicable disease pathogen or vaccine is production of: Immunoglobulin G (IgG) Immunoglobulin M (IgM) Immunoglobulin A (IgA) Immunoglobulin C (IgC)

Immunoglobulin G (IgG) Immunoglobulin M (IgM) Immunoglobulin A (IgA) Immunoglobulin C (IgC) IgG -Think G Disease is Gone; major antibody of the secondary immune response IgM - Think M for making antibodies; is the predominant antibody in the primary immune response IgA - found in secretions; immune function of mucous membranes IgD - is present in large quantities on the membrane of B-cells - works with IgM in B cell development IgE - may play a role in immunity to parasites but is more commonly associated with type I immediate hypersensitivity

Aerobe Obligate anaerobe Facultative anaerobe Microaerophilic aerobe A microbe that can grow in the absence of oxygen but is also able to utilize oxygen for growth is a/an: Aerobe Obligate anaerobe Facultative anaerobe Microaerophilic aerobe

Facultative anaerobe: Obligate anaerobe Facultative anaerobe Microaerophilic aerobe Aerobe: grows in presence of oxygen (O2) Obligate anaerobe: Only grow in absence of O2 Facultative anaerobe: Will use O2 if available but are able to grow in the absence of 02 Facultative = occurring optionally Microaerophilic aerobe need a small amount of O2 to grow
