100
This is a sudden increase of a disease in a localized area.
What is an outbreak?
100
An infectious agent that is multicellular, eukaryotic, and reproduces via spores
What is a fungus?
100
The type of transmission when a disease is transmitted via inhaled infectious particles, infected surfaces, or an insect
What is indirect contact?
100
A scientist that studies microscopic life.
What is a microbiologist?
100
The cell morphology of a spherical bacterial cell.
What is coccus?
200
A disease acquired in the hospital.
What is a nosocomial infection?
200
The infectious agent that is non-living and requires a host to reproduce. A protein capsid around either DNA or RNA.
What is a virus?
200
The number of pathogen particles (bacterial cells, viruses, etc.) that are required for infection to occur.
What is an infectious dose?
Note: higher infectious dose is a weaker pathogen!
200
An example of aseptic technique.
What is the usage of gloves, clamshelling a petri dish, disinfecting a surface, etc.?
200
The colony arrangement (etymology means "bunch of grapes") where bacteria are in groups or clusters.
What is staphylo-?
300
The group that works with hospitals to control outbreaks.
What is a DDT?
300
When an infection damages the structure or the function of the host's tissues.
What is a disease?
Note: this is different than an infection, where the infectious agent enters and multiplies inside the body.
300
The type of immunity that is specific and delayed. (Antigens of a pathogen are recognized, B and T-cells are activated, antibodies agglutinate specific pathogens)
What is acquired (adaptive) immunity?
300
The technique to view individual colonies of bacteria, done by taking bacteria applied to the petri dish in the previous streak to a new section of the petri dish
What is an isolation streak?
300
Drawing of streptobacillus.
something like that.
400
The timing in this scenario:
North Central communicates via a parentsquare message the incidence of a lice outbreak 3 days after the junior prom to parents and the school board.
How long is three days after prom?
400
The infectious agent of Ringworm.
What is a fungus?
400
The number of people infected with a disease whose R0 is 0.67
What is, on average, 0.67 people?
400
The accurate placement of petri dishes in an incubator AND the reasoning.
What is upside down (stranger things reference)?
Preventing condensation from damaging bacterial colonies.
400
The color of gram-positive bacteria.
What is purple?
500
A scientist that studies the spread of disease.
What is an epidemiologist?
500
An example of an "infectious agent" that is not "bad" for humans.
What are gut bacteria, medicinal/edible fungus, etc. (other answers could be correct!)?
500
The difference between natural and artificially acquired immunity.
Natural: exposure to pathogens causes an immune response and then immunity.
Artificial: immunity gained through medical intervention (a vaccine or an antibody transfusion)
500
The descriptor of bacteria that describes the edge of the bacterial colony. Examples include: entire, undulate, filiform, curled, lobate.
What is margin?
500
The function of the counterstain.
What is using safranin to add pink/red pigment to the decolorized bacterial cells?
Note: the gram-positive bacteria are also stained, but the color does not show due to the exiting purple stain from the Crystal Violet-Iodine
