A Third Bioscreen Report with Patient Experiences

A reader wrote with some specific questions and shared her BioScreen report. I will first do my standard review and then address the questions. Remember, I am not a medical professional — more a librarian who knows how to lookup things, read things (ex-technical writer) and apply logic.

Basics Criteria



And as usual, their automated comments on each, for example:


  • Low E.coli – as expected
  • Low Lactobacillus – as expected
  • Normal Bifidobacteria — BUT only one species.. i.e. all of the other species are missing!

Analysis of Over Growth

As usual, I head to datapunk.net to speed analysis (and allow folks to check or extend my research).

  1. Bifidobacterium pseudocatenulatum (species) Note: I deem this to be an overgrowth, because it is the only bifidobacterium!
  2. Streptococcus parasanguinis (species) 
  3. Collinsella aerofaciens (species) 
  4. Propionibacterium acnes (species)  I included this because it was there with no reference levels — i.e. unexpected growth!

Note: [Parent] below indicates that it applies to bifidobacterium and not this specific species (which we know nothing specific about)





Questions and attempted answers



Q:  My main overgrowth is Streptococcus Parasanguinis, I believe this lives in the mouth and is normally killed by the stomach acid. Does this automatically mean that  I have low stomach acid, and if so, this problem can not be repaired until the stomach acid issue it cleared. Or could it be that the strain I have has somehow adapted to with stand the acid in the stomach. I have also read somewhere that people with CFS can not produce enough stomach acid due to the high amount of energy required to do so, what are your thoughts. Is this strain of Strep overgrowth common?

A: DataPunk cites ” The presence of S. parasanguinis in the oral cavity is associated with a healthy microflora. Identified as a constituent of the oral microbiome by Human Oral Microbiome Database. Identified as constituent of vaginal microbiome. [PMID:23282177]”

There are a large number of potential cooking items listed above that should suppress it in the gut. These include:


Q: Do you recommend antibiotics, rather than herbs for my situation, if so which ones.

A: I always prefer non-antibiotics as the first choice. Antibiotics tend to have cascading side effects (‘casting out a demon from the house, and a dozen more takes it place’ syndrome). If you go the antibiotic route — make sure that you are not given an antibiotic that worked when your MD went to Medical School and is ineffectual now (See this search)

Q:  I also have a parasite (Blastocystis) which I believe this is very difficult to get rid off and requires multiple antibiotics. My thoughts are to ignore this for now until the bacteria is in a better place and then readdress it. What would your advise be?


A: I checked PubMed and found some studies of interest

Q:  I have had a bad herx from Prescription assist (dizziness, spaciness, bloating) however by the time I finished the 1st bottle I as able to take two caps per day and was feeling much better (no herx.)

A: Thank you for sharing! A herx can happen — my two worst were from Mutaflor and Lactobacillus Fermentum ME-3. As with you, the herx disappeared and I felt a lot better afterwards!

Q: I have just started on symbio 2. I started on one drop and by day three was up to the standard dose as I had no herx & felt a huge improvement in all my symptoms and energy (the best I’ve felt for months). Can you confirm that we need to take both Symbio 2 and Mutaflor or just one or the other? 

A: My own opinion is that if there is not an economic issue, do both. Symbioflor-2 standard dose is much less than Mutaflor standard dose (which is why I like suggesting using Symbioflor-2 to start). They are different strains.

Q: . I took a low dose of thyme and rosemary oil as an antibiotic, Interestingly my blood pressure dropped and I experienced POTS. These are CFS symptoms I have not experience for a few years since I started drinking liquorice tea daily in order to increase my blood pressure (which it did). I  wonder if bacteria affects blood pressure and causes POTS which a very common symptom in CFS.

A: There is a recent article that may answer that question:
The Microbiome and Blood Pressure : Can Microbes Regulate Our Blood Pressure? [2017]  “Studies have described how dysbiosis may modulate blood pressure and contribute to CVD. ”
