SCRIPT 2026 COMPLETE QUESTIONS
CORRECT SOLUTIONS
◉ cluster
Answer: what does staph mean
◉ Skin/mucus membranes; rarely pathogenic
Answer: what are the characteristics of Staphylococcus epidermidis
◉ Skin/mucus membranes; pathogenic w/ portal of entry
Answer: what are the characteristics of Staphylococcus aureus
◉ Strep throat
Answer: what does Streptococcus pyogenes cause
◉ Pneumonia/ear infections
Answer: what does Streptococcus pneumoniae cause
,◉ Dental cavities
Answer: what does Streptococcus mutans cause
◉ Gastrointestinal tract
Spread to other areas via cuts, wounds, poor hygiene
Common cause of bacteremia/endocarditis
Often exhibit multi-drug resistance
Answer: characteristics of Enterococcus species
◉ glass slide
Answer: what did we preform the gram stain on
◉ S. aureus and Streptococcus pyogenes
Answer: what bacteria did we use for the gram stain
◉ Smear preparation protocol:
1) Add 1 loop of water to slide
2) Add 1 loop of microbe to water
3) Air dry and heat fix
4) Stain with crystal violet, add iodine, then acetone alcohol, then
safranin
5) Put into bibulous paper
,Answer: how did we prepare the gram stain
◉ Streptococcus pyogenes, positive
Answer: what is this bacteria? is it gram positive or negative?
◉ Staphlococcus aureus, positive
Answer: what is this bacteria? is it gram positive or negative?
◉ catalase test
mannitol salts
blood agar
bile esculin
salt tolerance
Answer: what procedures used gram positive cocci
◉ to see if microbes produce catalase enzyme
Answer: why do we do the catalase test
◉ S. aureus and Streptococcus pyogenes
Answer: what bacteria do we use for a catalase test
, ◉ 1) Add 1 very thick loop of microbe directly to slide (no water
should be added)
2) Place 1 drop of hydrogen peroxide on microbe
Answer: what is the procedure for a catalase test
◉ S. aureus
Answer: which bacteria had the catalase enzyme
◉ the enzyme breaks down hydrogen peroxide into water and
oxygen gas
Answer: why does bacteria bubble if it has the catalase enzyme
◉ Selects for the growth of a specific group of microbe
Answer: what is a selective medium
◉ -Differentiates between two groups of microbes
-Usually use pH indicators to do this
Answer: what is a differential medium
◉ -Selects for the growth of a specific group of microbe
-Differentiates between two species within the group
Answer: what is a selective and differential medium
