[pct-l] More Giardia dizinformatzia

 I think you misunderstood the good doctor, in a casual conversation.
People can drink water that has giardia in it, and still not catch giardia.
This can happen because you picked part of a giardia-infected lake that has
few organisms, so your bottle didn't get any in it. (Important lesson--
there is a place in a given body of water, where you are MORE likely to get
infected). Or, you can drink water that has giardia in it, but not get
infected, simply because the cysts passed through you, or were digested.
This can happen, but is relatively uncommon-- giardia is quite efficiently
infectious. In either case, it is easy to misconstrue this even as "being
resistant to giardia".

Medical science, in fact, knows of NO cases of resistance to giardiasis.
Life-long giardia infection is common in the third world. More than 80% of
these persons continue to have bouts of giardia symptoms off and on, for
their entire lives. Many persons of the tropics do not even know what an
American means, when one describes firm stool, stool without mucus, or days
without symptoms of belching or indigestion. However, it is certainly true,
that the nature and severity of the illness does change over years of
infection in a given individual. But most of "getting used to giardia" is
in the head, not in the gut or immune system. Having bouts of diarrhea and
missing work due to GI illness is normative behavior, in the Third World.

 People living in the thirld word are RAVAGED by the polluted, infectious
water that they drink. It is one of the greatest causes of their shortenned
life-spans. When they drink a new bug, they get sick, just like we do.

If you had a doctor examine your stomach, he WOULD NOT find all kinds of
nasties. If he did, they should be treated. You WILL NOT ADAPT to them,
unless your idea of adaptation is to happily blow foul diarrhea a few times
a night.
