Intro and Bacteria
Infectious agents with 100 nanometer particle sizes are likely to be these
What are viruses
Cold sores/ fever blisters are signs of this part of a viral life cycle
What is a lytic cycle
Infection due to a disease that is constantly present at a low level in a population is described as this
What is endemic
Inflammation is part of this line of body defenses
What is the second line of defence
Most common type of oral cariogenic bacteria
What are streptococci (S. mutans)
It currently ranks 4th in worldwide mortality for infectious diseases
What is tuberculosis
A fungal infection that usually starts via inhalation of aerosolized bird droppings or dust from soil that is most common in the great lakes area
What is blastomycosis
Infections caused by medical interventions are specifically described this way
What is iatrogenic
Antigen presenting cells derive from these types of immune cell
What are macrophages
The TSST superantigen most often derives from pathogenic strains of this bacterium
What is Staph. aureus
Under poor growth conditions, Bacillus anthracis forms these
What are (bacterial) endospores
The "SC" for PrPsc stands for this
What is Scrapie
N95 masks are HEPA grade, meaning they can stop particles of what particle size or smaller?
What is 5 microns (micrometers)
In a secondary immune response, most antibodies produced are of this type
What are IgG
If blood agar becomes clear (white), it means the bacteria can be classified this way
What is as beta-hemolytic
It precedes the stationary phase when bacterial growth of batch cultures is monitored
What is the exponential phase
A severe development of this type of protozoan infection which usually starts in the GI tract, is the formation of liver abscesses
What is amoebiasis
A chemotherapeutic that is specific for tuberculosis infections which inhibits mycolic acid synthesis
What is isoniazid (INH)
A biological macromolecule that usually ranks as least antigenic
What is nucleic acid
A serious complication of viral influenza infections in children and also associated with use of aspirin
What is Reye's syndrome
E. coli should stain this colour after Gram staining
What is red
Obligate anaerobic bacteria that were covered in this course were mainly of this genus
What is Clostridium
Paxlovid targets this viral component to prevent SARS-CoV-2 from replicating
What is (viral) protease
How we would classify the type of immunity conferred on a person who received an intramuscular injection of a vaccine
What is artificial and active
The proportion of VZV infected individuals who would develop shingles later in life
What is 15%
