- H-antigen (flagellar)
- K-antigen (Capsule)
- O-antigen (cell wall)
What do these types of E. Coli dp/cause:
EHEC
ETEC
- EHEC= Produces shiga toxin that causes hemolytic uremia syndrome
- ETEC= Produces LT and ST toxin that causes diarrhea
What do these types of E. Coli do/cause:

EAEC
E. Coli H7
EAEC= aggregate in mucosa, release enterotoxins
E. Coli H7= Causes food poisoning
Klebsiella pneumoniae
