A
Adhesion to host cells
- Specialised pili/fimbriae
- Cell wall/capsule
- Adhesins
Secretory mechanisms
- export/deliver toxins, enzymes, invasions (invasion, spread, acquire nutrients)
Motility/Chemotaxis
- spread to new sites + communicate with each other
2
Q
Adherence
A
Attachment needed to avoid being swept away favourable environment/niche
GIT, lungs, UT
3
