No... I was discussing one of my babies with the doctor.

I don't know how H. pylori works but I can tell you that there is no
way that if you swallow a ball of phlegm that it will survive, intact,
on a trip through the stomach and intestines and be seen again in your
stool.

I think it's very likely that if you have a cold/sinusitis/whatever
making your nose run...  your stomach is likely upset for other reasons
but it helps to make this mucus/tummy ache myth persist.

He're my source...  :)

Please refer to the Michael's post in the
stomach upset and post nasal drip thread.

look for  the sentence "causes emisis in the primate model."

"Staphylococcal Enterotoxins

The SEs, SEA through SEI except SEF, are produced by various
coagulase-
producing staphylococci. Although known for many years as the cause of
SFP, they have only recently been shown to be superantigenic, and in
particular SEB and SEC have been implicated in nonmenstrual TSS. All
SEs thus far characterized have the immunomodulatory properties of
superantigens, and several have been demonstrated to be lethal in the
rabbit model of TSS. Molecular studies of the SEs have shown that
superantigenicity and the capacity for causing SFP are determined by
separate parts of the protein (2, 67). Several reviews of SEs are
available, and other sections of this review provide background on
toxin genetics and TSS pathogenesis.

All toxins thus far identified share a number of important properties
(10, 12, 24, 26), including (i) an ability to cause emesis and
gastroenteritis in a primate model, (ii) superantigenicity, (iii)
intermediate resistance to heat and pepsin digestion, and (iv)
tertiary structural similarity (where known) including an
intramolecular disulfide bond. "

Note point (iii) intermediate resistance to ... pepsin digestion,
