Following are excerpts from a small selection of emails received
since the Blastocystis hominis section was added in early 2000:
J is 27 years old and lives in Calgary, Canada. He was diagnosed with Blastocystis hominis after a trip to Jamaica. He described his symptoms as feeling "light headed, a low
grade fever, terrible stomach cramps, loss of appetite, unable to sleep. He also lost
20 pounds in only a few weeks. One of three fixed stool samples was positive for Blastocystis hominis. He was treated with Iodoquinol and Flagyl for 28 days. The drugs failed to eradicate Blasto. J. returned to his dr for advice:
"He told me that we are no longer going to be treating this condition as Blasto but rather he wanted to look other causes since he thought that Blasto. could not have lasted through this treatment and could not give me symptoms for so long. He has spoken to the Infectious/Tropical Disease department here in Calgary as well as with the Travel Medical Clinic and they agree with his decision They all feel that I must have IBS or Colitis since this has been going for four months now. I am very upset about this but I do not know what else to do. They want me to go for a colonoscopy in the next couple weeks to see what is going on inside of me as well they want me to do for even more blood, urine & stool tests. I have given up with the Canadian medical system"
received May 2005
" I mentioned to ( the
travel health dr ) about testing for Blasto. and D.fragilis.
He said the test is done in the ova & parasite here their labs.
He also said Blasto. is the most common parasite - it shows up all
the time in hundreds of patients - BUT HE NEVER TREATS IT. I showed
him some of your case histories (printed out your entire web site)...he
said the reason it is possible ( some people
recover with drugs ) is timing, they may have gotten better
on their own. He believes something else is causing the health problems
the usually eventually resolves it self." (received
from mother of 11 year old son with undiagnosed chronic digestive
symptoms. He has not been tested for either Blastocystis hominis
or Dientamoeba fragilis).

Chiodini, at the London School of Tropical Hygiene and Medicine

him to send in three stool samples for more accurate detection of
parasites. He was diagnosed with amoebic dysentry (infection with
the parasite Entamoeba
histolytica), as well as Blastocystis hominis.
P. was referred to the London School of Tropical Hygiene and Medicine:
" I have just come back from a
very dissapointing meeting with a consultant in the tropical deseases
hospital in London. He basically told me that B. hominis doesn¹t
cause symptoms and even if he did treat it it would be with the
antibiotics you have outlined (which don't seem to work) on your informative website. So
Im stuck! Ive had every test under the sun and parasites are the
only thing they have found."

results after finishing Flagyl were negative for E.histolytica,
but still positive for Blasto.
I questioned P as to whether his health care providers had considered
the stool test was innacurate and that he may still have E. histolytica,
based on his symptoms of chronic health problems.
He replied: "Your
questions on Entamoeba histolytica are quite interesting as no one
around me has taken this issue seriously. I was given two courses
of Flagyl and one stool test at the end which was negative. Apart
from that I asked my Gp to test me again three months later. He
did one stool test which came back negative but I was experiencing
the symptoms of dysentery! My consultant at the hospital dismissed
my ideas that the amoebic dysentry could still be around in my gut
and the matter went no further. I have not got a very good gp who
has no real knowledge of dysentery so no they didnšt discuss the
effects of Entamoeba histolytica with me."

My first symptoms occured when I was deployed to Kuwaitt this past
November. We were told not to drink the water there, but I used it
to brush my teeth. I had to go to the hospital not too long after
I got there and I was in extreme pain. I was shaking throwing up and
so dehydrated. I had never felt pain like that before, I was hoping
to just die. Well, the millitary doc's said I was just dehydrated
and that caused my intestine to stop working momentarily and once
hydrated I would be fine. Ever since then I have not been the
same. I would wake up in the middle of the night walk out my tent
and throw up. I did this for a week straight. My bowel movements have
never been the same. I have constent water diahreah and every once
in a while it's soft and basically like rubber cement. I was living
in Las Vegas at the time and when I moved to South Carolina I found
a Doc that was willing to work with me. I first took flagyl, (felt
better while on, but everything came back when done) then flagyl and
bactrin. This combo made me feel really sick while on it and I felt
better after. Then it came back three days later. I went to a GI specialist
last week and I see him again in a week and a half, but he says he
thinks it's IBS. I am not currently in the Air Force, but am looking

Bowel Syndrome, despite a positive test for Blastocystis hominis:
"I am currently suffering from what my Dr. thinks is IBS .
My symptoms began with a feeling of nausea, fullness, bloating,
intermittent diarrhea and constipation .
Treatment was refused.
12 years the following US woman travelled and worked in tropical and
third world countries considered
high risk areas for contracting parasites .
In Dec 2000 she began to suffer gastro-intestinal symptoms including
diarrhoea, bloating & belching. She was twice admitted to the
Emergency Room for administration
IV fluids due to dehyradation. She wrote:
"one of the most frustrating experiences was indeed getting past
my primary care physician! He had a single test for ova & parasites
done at a neighborhood lab and when that came back negative, he outright
refused to write me a referral to see a doctor at tropical medicine
even given my extensive work related travel in the tropics."
She had no further tests and her physician " insisted " she try a month of the drug Ranitidine followed by Pantoprazol. These
drugs are used to suppress stomach acid and have the potential to
cause bacterial overgrowth leading to gastritis ( Gastroenterology.
2002; Pharmacol Toxicol 2001 ) .
The drugs didn't help, and a month after being on the second drug,
Pantoprazol, she suffered a severe attack of diarrhoea and dehyradation.
The emergency room doctor advised her to stop
taking the drug immediately and after re-hydrating her intravenously
she was tested for Shigella, Camphylobacter and Salmonella. The tests
She then returned to her primary care physician
and told him that she:

be seen in a TFT test, that is, the direct preparation, not the ridley
Having tested positive for B.hominis, she then
consulted an expert in tropical medicine. However, her problems
were far from over:
" He wasn't convinced that B.hominis was the source
of my gastro-intestinal distress . He nonetheless put me on
a one-time high dose of tinidazol (2 mg) given my travel background,
and said that would be the last that he would see me .
The tinidazol made me very ill for several days thereafter. I went
back to the specialist at tropical medicine, and begged him if he
could please authorize another TFT test at the parasitology lab. It
came back again positive in large quantities for B.hominis. The
specialist told me I was swallowing air, and sent me home."

very much enjoyed reading your website knowing that after all I
am not alone in my suffering. Your story sounds so familiar to what
I have gone through but I guess that is a comment you must have
heard many times.
In October last year I was finally diagnosed with both Blastocystis
hominis (through a stool sample)
My diagnosis was made by doctor number 14 after I had seen some
5-6 GPs, four different gastroenterologists , 1
psychiatrist (who claimed to know all about nausea and recommended
Mindful Meditation and Existential Psychotherapy), 2 neurologists
and 1 immunologist (who found an elevated CD 4 count
but no viruses or bugs in two stool samples).
Over the last six years I have had all the tests that I read about
on your site ( colonoscopy, two stomach examinations, biopsy
of the small intestine, small bowel follow through, MRI of the brain
and neck, numerous X-rays, dozens and dozens of stool samples, etc... ).
My nausea was so bad for a period of three months
that I was retching three times a day after every meal. In contrast,
for most of the year 2000 I was nauseous only in the mornings but
each and every day! For short period in between I had been better
but never completely well.
Since the diagnosis was made last October I have been on doxycycline
for two months (which made me feel worse towards the end), clarithromycin
for two months (which did not appear to do much) and now cyprofloxicin
for two months.
All along I should have listened to my wife who had been telling
me from day one that I suffered from parasites! Sadly enough I put more trust in some 14 fancy doctors who
probably dump many difficult cases in the IBS/stress category."

really don't think a parasite specialist is what you should

It almost never is identifying the single totally solvable answer

abdominal pain, cramping, loss of bowel control, headaches, possible
rectal bleeding". A g/i physician diagnosed IBS and advised
adding fibre to her diet, the drugs Donnotol and Bentyl, none of which

Sometimes extreme pain. I am so frustrated. I AM EXTREMEMLY FATIGUED.

have just received results this AM that my 11 year old daughter has
Blastocystis hominis. This was discovered only after insisting for
years that something needs to be done about her severe abdominial
pains. She has always for as long as I can remember had abdomonial

pain long enough. When I arrived at work I found this website and
have learned a lot. "
