Are exotoxins only secreted by gramnegative bacteria? I read that LPS are the same as exotoxins, so it would follow that only gramnegative secrete them.

Best ResponseYou've already chosen the best response.0I might be wrong. I am just trying to figure out whether exotoxins and LPS are the same, in which case they don't pertain to grampositive.

Best ResponseYou've already chosen the best response.1exotoxins are mostly produced by gram + ones and endotoxins by gram  ones. LPS is not an exotoxin it is present in gram negative bacterial cell wall and it's lipid A component works as an endotoxin thatis notorious for gram negative sepsis and systemic symptoms.
