Talking about virulence factores they said

1) Mucosal interaction

2) Exotoxin production:

THIS IS MY QUESTION:

2) Exotoxin production:

a) Heat-labile and stable toxin (LT and ST) What this mean?

b) Shiga-like toxin. What this mean?

This I understand :
3) Endotoxin:lipid A portion of LPS
4) Iron-binbing siderophore: Obtains iron from human transferrin or lactoferrin.

Book : Cinical Microbiology made ridiculously simple edition 2.

These should help you out with shiga-toxin and possibly the others.

usmle is not going to relate the parasite to the nephron.They want you to know the life cycle of the parasite and how to treat it!!
