Microbiology Quiz: Gram Negative Bacteria

Gram Negative Respiratory Tract

• Multiple Choice Questions:

  • What is the common Gram-negative bacterium responsible for community-acquired pneumonia?
    • A) Klebsiella pneumoniae
    • B) Haemophilus influenzae
    • C) Legionella pneumophila
    • D) Escherichia coli
    • E) Moraxella catarrhalis

• Rationale:

  • A) Klebsiella pneumoniae is a Gram-negative bacterium, but it is more commonly associated with hospital-acquired pneumonia.
  • C) Legionella pneumophila is a Gram-negative bacterium, but it is typically associated with Legionnaires' disease, not community-acquired pneumonia.
  • D) Escherichia coli is a Gram-negative bacterium, but it is more commonly associated with urinary tract infections.
  • E) Moraxella catarrhalis is a Gram-negative bacterium, but it is more commonly associated with otitis media and sinusitis.
  • Which of the following Gram-negative bacteria is often associated with chronic obstructive pulmonary disease (COPD) exacerbations?
    • A) Pseudomonas aeruginosa
    • B) Stenotrophomonas maltophilia
    • C) Burkholderia cepacia
    • D) Haemophilus influenzae
    • E) Acinetobacter baumannii

• Rationale:

  • A) Pseudomonas aeruginosa is a Gram-negative bacterium, but it is more commonly associated with cystic fibrosis and hospital-acquired infections.
  • B) Stenotrophomonas maltophilia is a Gram-negative bacterium, but it is more commonly associated with hospital-acquired infections.
  • C) Burkholderia cepacia is a Gram-negative bacterium, but it is more commonly associated with cystic fibrosis.
  • E) Acinetobacter baumannii is a Gram-negative bacterium, but it is more commonly associated with hospital-acquired infections.

Gram Negative Zoonotic Origin

• Multiple Choice Questions:

  • Which of the following Gram-negative bacteria is typically transmitted through the bite of an infected flea or tick?
    • A) Brucella
    • B) Francisella
    • C) Yersinia
    • D) Bartonella
    • E) Pasteurella

• Rationale:

  • A) Brucella is typically transmitted through contact with infected animals or contaminated dairy products.
  • B) Francisella is typically transmitted through the bite of an infected tick.
  • E) Pasteurella is typically transmitted through animal bites or scratches.
  • Which of the following Gram-negative bacteria is typically associated with cat-scratch disease?
    • A) Brucella
    • B) Francisella
    • C) Yersinia
    • D) Bartonella
    • E) Pasteurella

• Rationale:

  • A) Brucella is typically associated with animals and contaminated dairy products.
  • B) Francisella is typically associated with tularemia.
  • C) Yersinia is typically associated with gastrointestinal infections.
  • E) Pasteurella is typically associated with animal bites or scratches.
  • Which of the following Gram-negative bacteria is typically associated with plague?
    • A) Brucella
    • B) Francisella
    • C) Yersinia
    • D) Bartonella
    • E) Pasteurella

• Rationale:

  • A) Brucella is typically associated with animals and contaminated dairy products.
  • B) Francisella is typically associated with tularemia.
  • D) Bartonella is typically associated with cat-scratch disease.
