  Please be careful with your attributions. I did not write the article
to which you replied in the post quoted above. In fact, I am in agreement
with the points you make here. My previous contribution to this thread was
to state that I am not aware of anyone in spirochete research who believes
Lyme borreliosis is in all cases responsive to short-term antibiodic therapy;
the fact that this disease can be refractory to treatment is well illustrated
by the example you give above and is a concern we share.
  One observation on the above is that simply asserting the lack of accuracy
of antibody tests for Lyme borreliosis understates the problem somewhat. A
serodiagnostic tool that would unequivocally distinguish Lyme borreliosis from
the diseases caused by spirochetes in the genus Treponema is greatly to be
desired. As it stands, a Lyme serum will light up any of the treponemal tests
for syphilis (such as FTA-ABS or MHA-TP), a fact that further complicates the
use of the cardiolipin-based non-treponemal screening tests for syphilis (VDRL,
RPR). And this does not address the problem of distinguishing among the
treponemal diseases (syphilis, endemic syphilis, yaws, and pinta). Thus
diagnostic problems can be severe when confronted with the disseminated forms
of Lyme borreliosis and syphilis (and its cousins) in the absence of some
definitive history, as these diseases can manifest very similar symptom
complexes. And here I am not addressing the protean symptomology of early
Lyme borreliosis and the problems caused by the frequent absence of classic
manifestations such as erythema chronicum migrans. Syphilis has been called
"the great imitator" because it can mimic many diseases; Lyme borreliosis
is called "the new great imitator." Rather than beat this to death and still
not do it justice (both of which I think I already have accomplished), I
would be happy to email a lengthy list of references to anyone interested.
 Finally, treatment failure, a problem especially acute in the case of Lyme
borreliosis, is more than a pharmacological abstraction; it is a tragedy (a
very important point Marc makes).

  To return to newsgroup relevancy, as a Californian transplanted to Houston,
I miss mountains. I recently made the 700 mile pilgrimage to the nearest
mountains (in Big Bend N.P.), and had a very interesting desert/mountain
backpack (Chihuahuan Desert/Chisos Mountains). This is rugged, beautiful
country.
