Thanks yahia!
I can almost guarantee you that even in people with IBS where they look for Blastocystis the percentage they find with blasto is under estimating the true percentage of IBS patients with blastocystis.
The reason is blasto can be very hard to find with microscopy looking for it, even in a good lab. I posted earlier a paper that shows that microscopy method (stain) designed to look for blasto only have 60% detection rate (in infected indviduals). The detection rate can be increased by taking many samples etc. Very very few commercial (non-research) labs if any use culture or PCR that from what I have read have much higher detection rate.
3 samples are not always enough! May be it give 80% detection rate (may be 70%, may be 90%??) in a good lab that know how to look for blasto. This would mean 20 out of 100 infected individuals with IBS still would go around with undiagnosed blasto, getting diagnosis like IBS, small bowel overgrowth, chronic fatigue syndrom, fibro myalgia, or some other crappy symptom diagnosis.
Most doctors do not seem to be interested in staying on top of the research papers, and even if they read them they seems to ignore them?
Many doctors behave like they need 100% proof it is pathogenic before they get interested in it.
