Erm... 

It appears I've been making myself misunderstood a bit too often. This wasn't really an improvement—Pseudomonas is very, very, very rarely associated with necrotizing fasciitis. I mean, there have been like a dozen cases reported in the literature if I recall correctly. What I meant by my comment over at WT:MED was that very dramatic cases such as this one are really not that uncommon—many people who develop necrotizing fasciitis, for instance, have equally dramatic and unfortunate disease courses. I did not mean to imply that necrotizing fasciitis is caused by Pseudomonas, and I'm sorry if my comment led to any confusion behind your edit.  (t·c)
