Quiz Answer Key and Fun Facts

1. What is the role of crystal violet in the performance of a gram stain?

Answer: stain

Crystal violet, a stain, is fixed to the bacterial cell wall by the mordant, iodine. After decolorization and counterstaining with safranin, bacteria appear purple (gram positive) or pink (gram negative).

2. Which of the following is a gram negative rod?

Answer: Klebsiella pneumoniae

Staphylococcus aureus is a gram positive coccus, Listeria monocytogenes is a gram positive rod, and Neisseria lactamica is a gram negative coccus. Klebsiella pneumoniae is a urinary tract and respiratory pathogen.

3. Which of the following is a gram positive coccus?

Answer: Streptococcus pyogenes

Haemophilus influenzae, Escherichia coli, and Pasteurella multocida are all gram negative rods. Streptococcus pyogenes, or Group A Strep, is the causative agent of strep throat.

4. Which of the following is associated with neonatal sepsis due to a disruption of the normal flora of the birth canal?

Answer: Streptococcus agalactiae

Streptococcus agalactiae or Group B Strep can cause sepsis, meningitis, and death. The CDC recommends screening pregnant women for the bacteria prior to delivery so appropriate treatment can be initiated.

5. Which of the following is associated with cat bites?

Answer: Pasteurella multocida

Pasteurella multocida is found in the feline oral cavity and is the most common cause of infection after a cat bite.

Answer: Listeria monocytogenes

Listeriosis is a serious infection. The mortality rate is 20%. One third of all cases involve pregnant women, the fetus being affected more than the mother.

9. Which organism is the most common causative agent of urinary tract infections?

Answer: Escherichia coli

While all of these organisms can cause urinary tract infections, Escherichia coli, AKA E. coli, is the most common culprit.

10. Which of the following is considered a potential agent of bioterrorism?

Answer: Franciscella tularensis

Franciscella tularensis is the causative agent of tularemia or rabbit fever. Hunters are at risk for contracting the disease due to contact with animal hides. It can be contracted by inhaling the bacteria which makes it an effective agent of bioterrorism.
