Which is more dangerous, gram-positive or gram-negative?

[NinaBanina]

Even after looking at several sources I'm still confused as to which Eubacteria are more dangerous, gram-positive or gram-negative. I know that both are the cause of various disease but it doesn't explain to me which would be considered the most severe threat to other organisms.

Well, as long as I know, most gram-negative bacteria are pathogens. According to their cell wall structure which has the Lipopolysaccharides on top of its outer membrane. Lipopolysaccharide is toxic chemical for human. You may use this reason to say that gram-negative bacteria have more severe threat. Good luck!!!
