Not a very interesting conflation.

Again, Your Common Knowledge is ,...well, uncommon (oh, Thanks Google-man).

Reiter's is a very specific case, but with any persistent ReA, the model of molecular mimicry applies: No matter which the inciting germ is, after several months that germ is no longer involved in the disease process.

Symptoms evolve. And in susceptible individuals the disease becomes KRA/AS.

One--and only one--opportunistic bacterium that is stealthy and difficult to identify apart from normal bowel flora is the ultimate culprit in every case. It replaces the causative agent that has damaged the tract.

And it is not just bacteria, protista, fungi, worms, and other parasites that can incite KRA/AS symptoms, but even mechanical damage to the gut can cause this disease: Gastric bypass is another cause and probably enough cases have been induced by NSAIDs to be of real concern.

So, advice if You are going to get an ReA; do not be susceptible.

[quote]Jeanne Kirkpatrick: [ peeved ] May I say something, please? This program is an outrage! This program just doesn't do justice to the educational system, which upholds the fragile civilization of our country together!

Bob Albert: Oh well, sor-ry Je-anne! Les is still our champion, but you'll be going home with $400 and a year's subscription to TV Guide! TV Guide, the most widely-read publication in the world.

Jeanne Kirkpatrick: In the United States.

Bob Albert: Oh, whatever you say! Well, anyway, that's "Common Knowledge". And remember: It's not what you know, but what you think you know! Good night, everyone!

Half the story never gets the job done. No points.
