0 The Friday Four

Ed. note - This late edition of the Friday Four almost became the Saturday Six, due to computer problems. I still consider it to be Friday Hawaii-time - so I'm not making changes to content.


1) Bacteria Can Affect Your Moods And How You Think [video - time - 1:45 ]

We Aren't Just Talking "Lyme Rage" here...



2) Gonorrhea acquires a piece of human DNA: First Evidence of Gene Transfer from Human Host to Bacterial Pathogen

If a human cell and a bacterial cell met at a speed-dating event, they would never be expected to exchange phone numbers, much less genetic material. In more scientific terms, a direct transfer of DNA has never been recorded from humans to bacteria. Until now.

3) 'Good' Bacteria Keep Immune System Primed to Fight Future Infections

Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why.

And related to the above, I bring you this food for bacterial thought...

4) Unraveling gut immune system, one microbe at a time

[This post was originally published at webeasties.wordpress.com]

The intestine is probably the most difficult organ for the immune system to deal with. First of all, it's huge (the surface area of the small intestine alone is about the same as a tennis court). Second, it's filled with microbes that the immune system would rather not deal with. The vast majority are totally harmless, and they tend to crowd out the ones that would actually be a problem. But on the surface, there's very little difference between normal, run-of-the-mill E. coli and dangerous, going-to-make-you-sick E. coli. So, how does the immune system tell the difference?

Thoughts on this:

1) You act and think the way you do to some degree because of bacteria... That is just amazing!

2) Keep taking those probiotics!

3) So IS pulsing the way to go when treating long-term infections?
