Which of the following is a virulence factor of Escherichia coli?

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.
