Think-Pair-Share Questions

Many pathogenic bacteria that infect the intestinal tract have flagella.

1. Why might having flagella better enable those bacteria to cause disease?

2. Our defense cells have a surface PRR called TLR-5 that recognizes bacterial flagellin. In terms of preventing infection, why is this an advantage?

3. Most pathogenic spirochetes such as Treponema pallidum and Borrelia burgdorferi disseminate from the original infection site. How are they able to do this?
