  1. Which tissue is infected? what virulence factors do your bacteria need to colonize,
  infect and survive in the tissue?
  2. What obstacles do the bacteria encounter in the first and second barriers and how are they counteracted?
  2. The structure of the microbe is presented (G + / G-, morphology, surface structures)
  3. Path of infection, ie colonization and infection of target tissue are included
  4. Suggestions for virulence factors for the infection are included.
  5. Suggestions for interactions with the immune system's 1a and 2a barrier are included.

Answer 1

1. Gastrointestinal tract or endothelial cells infected by bacteria. Toxins are virulence factor.

2. Hydrochloric acid kills bacteria, the acidic condition of stomach kills bacteria. anaerobic condition,

3.structre of G+ G_

4. Virulence factor Vi antigen
