Australians Win Nobel For Linking Bug To Ulcers

[xcamel]

except for the part where we came "out of africa" more like 175,000 years ago...

[IronJack]

Ulcers came into being just about the time wives did.

I'm sure it's a coincidence.

[relictele]

Doing the ulcering North Americans wouldn't do.

I had h. pylori last year and the cure for it was a nightmare. If it hadn't gone away, I told my gastro she would have to hospitalize me and do an IV drip before I would ever take that combo of meds again. Ghastly!

"Most cases of peptic ulcers and gastritis are caused by H. pylori, not spicy food and stress and spicy food as many thought until the 1990s. These conditions are now widely treated with antibiotics effective against the bacteria.

Just remember, not ALL cases, only most. The gastrointestinologists test for it, and if it's not there, then your ulcer is caused by something else.

Talking about pre-historic infections.

Retroviruses are viruses that reverse-transcribe their RNA into DNA for integration into the host's genome (see this http://www.maxanim.com/microbiology/Replication%20Cycle%20of%20a%20Retrovirus/Replication%20Cycle%20of%20a%20Retrovirus.htm for an animation)

Most retroviruses (such as HIV-1) infect somatic cells, but some can also infect germline cells and once they have done so and have been transmitted to the next generation, they are termed endogenous. Endogenous retroviruses can persist in the genome of their host for long periods. However, they are generally only infectious for a short time after integration as they acquire 'knockout' mutations during host DNA replication.

The published human genome sequence contains many thousands of endogenous retroviruses (HERVs) but all are defective, containing nonsense mutations or major deletions. Only the HERV-K(HML2) family has been active since the divergence of humans and chimpanzees; it contains many members that are human specific. This article http://jvi.asm.org/cgi/content/full/79/19/12507 indicates that the HERV-K(HML2) family may be active in present-day humans. The possibility that the family is active today is particularly important because it has been implicated in a range of human diseases.
