Questions & Step-by-Step Solutions

Which of the following is a virulence factor of Escherichia coli?
  • Step 1: Understand what a virulence factor is. A virulence factor is a trait or characteristic of a pathogen that helps it cause disease.
  • Step 2: Identify the pathogen in the question. The pathogen we are discussing is Escherichia coli, commonly known as E. coli.
  • Step 3: Learn about the different types of virulence factors. E. coli can have several types, including:
  • Step 4: Recognize that a capsule is a protective layer that helps bacteria evade the immune system.
  • Step 5: Understand that endotoxins are components of the bacterial cell wall that can trigger strong immune responses.
  • Step 6: Know that exotoxins are toxic substances secreted by bacteria that can damage host tissues.
  • Step 7: Conclude that all these factors (capsule, endotoxins, and exotoxins) are virulence factors of E. coli.
