An Array of Organisms Discovered in Stool: Where to Go for Help

Share the knowledge

A reader from Portugal writes to us after finding the organisms pictured below in her stool. The organisms vary in size and color, some being black/dark brown with segmentation along their ‘backs’, while others are a beige brown with a smoother body.

First of all, we feel it is important to provide viewer discretion. The following images may prove disturbing or upsetting to sensitive eyes. Secondly, although our reader does not specify what type of help she is requesting in her submission, we must make it clear that we will not be able to identify the organisms. Given that they were in her stool, and thus in her body, the situation becomes medical in nature. As we are not medical professionals, we are not qualified to make identifications of potentially parasitic organisms, as doing so would be tantamount to providing a medical diagnosis. Likewise, we are not qualified to give any suggestions for specific treatments or medications. What we can do to help is provide some resources our reader can use to find and consult with a physician who specializes in matters such as this.

To be more specific, we recommend that our reader consult a parasitologist. Otherwise known as an infectious disease physician, or simply a parasite specialist, a parasitologist is trained to identify and treat medical issues where an organism is involved. So, what we can recommend is that our reader do one or more of the following: 1) Search for a medical parasitologist in her area using this directory of medical parasitology consultants: 2) Search for a local parasitologist by doing a Google search for “medical parasitologist (name of the closest big city)” or “tropical medicine specialist (name of the closest big city)”. 3) Get in touch with Dr. Omar Amin at the Parasitology Center at 4) Contact Dr. Vipul Savaliya of Infectious Disease Care (“IDCare”) at Now, we recognize that our reader is from Portugal (or at least, her query was in Portuguese), and that, since we are a U.S. based organization, the following resources are unfortunately based in the U.S. That said, the two physicians mentioned above can consult with people online, and we imagine that if our reader contacts them, they could still be of help. Likewise, she could ask them if they are familiar with any counterparts in Portugal.

In conclusion, while we are not able or qualified to identify the organisms our reader found in her stool, we hope that the resources listed above are of help. Similarly, if any of our other Portuguese readers know of any Portugal-based parasitologists that they can recommend, then they are welcome to share any resources in the comments section below. We wish our reader the very best!

  1. I’m in need of help to been to Dr several times says I’m parasitic delusional . But it’s coming out of my right arm my stomach now I’m starting to feel it in my scrotum. I need help trying to find my own solution since the Drs aren’t doing anything for me

  2. I am a 31 yr old female that lives in Oregon that also has these disgusting creatures in my stool! I tried researching different types of parasites like nematodes and flukes, but nothing really looks like these! I find them, especially the hard leather like outer shell layer in all my bowel movements. They range from dark-reddish brown to black! It’s been since last November I’ve dealt with these disgusting things. I went to the doctor and they gave me Albendazole medicine, which is a anti parasite med, but it didn’t help at all! I’ve tried some natural remedies as well with no luck. I have severe chronic fatigue, skin itchiness, headaches, swollen ankles/ feet, nutrient deficiencies that won’t subside from taking high end vitamins nor eating healthy. The list of issues goes on and I’m at a loss on what to do, of course everyone around me thinks I’m a nut job. If anyone has any info please share!

  4. Me too IN ga same thing has tentacles sorta purple and hairy looking. I think there is mail female version

  5. I have the same exact photos like yours. The dark slimy looking one and the tan one with a shell that wrinkles or lines in the shell. But mine are older and bigger. Please email or text me to see pics… Anyone that wants to collaborate please contact me.

  6. Same!!! Is there anyway I can talk to one of you people above comments in private. My email is [email protected]
    I’m probably not supposed to be putting all this but I just need to talk to someone in private. I’m having the same issues.It’s kind of scaring me at this point

  7. Have any of you gone to….
    You can submit a photo or a thousand. This was developed for field diagnose in third world situations for medical type applications A 99%
    Accuracy is claimed, although it does not yet have FDA certification. It identifies Larva status only. It is amazingly fast. It is free after you supply your email and you sign in. It is free. They ask to retain a copy of the photo to improve the algorithm I believe. The photo needs to not be “blurry”, it helps to have it isolated in the frame but it appears to be able to ID with some background. The science and theory seems to be sound. I found it to be invaluble. I got more than one ID accurate. s.Mansoni, threadworm, s. tan?….pork tapeworm. % of accuracy stated were 99% for the tape worm which looked like a small green pea. The mansoni looked long Aquarian with a poiny shot appendage protruding from the left upper corner. All of these were visible to the eye and photo camera was an old I Pad —–> Since micro is not my area.. It so helped 1. My fears 2. Any self and not self sanity questions. And exactly what direction to self evaluate and poise myself since I am bipolar and being a disaplined researcher in Chemistry I was actually shocked and surprized to be laughed at for suggesting I had an image …she called it a ” matchbook symptom” because people used to bring in samples in old matchbooks. So I totally relate to your situation. I was doing the exact same behaviors expected for me in a research lab in employment….plus these things require many tests and might not be visible. One last note: I found human testing 3 in parellel while in veterinary sciences conversely they do 12.
    It seems also, several people (TX is said to have a silent epidemic w\Chagas Disease) who had to go to a vet. for diagnosis. (One funny- t. CRUZI is the causative pathogen not Ted!)
    Thank you… do wonderful work. As THIS IS NOT FUN!

  8. Unfortunately it’s here in Colorado as well. I have been dealing with these unknown organisms for over 2 years and they grow larger by number and size in both my stool and in my skin. (Before reading that one should not seek advice from their PCP or ER Doctor I did just that and received the reaction noted). I too am desperate to find an answer bc they have caused ulcers all over my skin (especially arms and back)., I suffer from severe brain fog, muscle aches, low vitamin levels, and I’m so fatigued that moving from my bed to the sofa is a chore.I will attach photos later and give a more detailed analysis. I just wanted you to know you are not alone.

  9. I literally pooped out what is visibly a common slug, just like the kind you see in your garden, without the shell. It was about 20-30% smaller than a common slug, but had all of the features. I was in disbelief. Has this ever been documented before? I flushed it before I realised I should have taken a picture or something.

    How is this even possible? a new kind of parasite ?

  10. Same exact things here in Louisiana. Been through several testing but I don’t think there is a test fir these slug looking things. Also gets these “skin” looking pieces – they have markings like a caterpillar or something. It’s very disturbing because it’s affecting my children as well.
