Fungi and the microbiome finally got on my radar. Apologies to some, but there is a lot of different items on the microbiome radar screen.

“Small intestinal fungal overgrowth (SIFO)… Two recent studies showed that 26 % (24/94) and 25.3 % (38/150) of a series of patients with unexplained GI symptoms had SIFO. …. but evidence for eradication is lacking.”

As I did with taxa years ago, I will be writing a blog on each one reviewing the literature. If there is sufficient data at the end, I may add it as a feature to Microbiome Prescription.

• CDC provides a list of known fungal diseases: Types of Fungal Diseases.
• For the current list of Fungi reviewed on this list, click Information of Different Types Of Fungi

One of my reader’s results motivated this choice. The data from a Thorne Microbiome Test. 9 out of 10 has less of it. The person also has a Crohn’s diagnosis.

Preventive for Fungi

The following are suggestions:

• Reduce and keep your living space humidity at 50% or lower (typically done by dehumidifiers). EPA recommends 30-50% [EPA]; we set our dehumidifiers for 35%.

• Use a HEPA filter appropriate to your space.

  Typically they are described as “Room Size: Up to 1500 sq.ft. maximum”. We are more aggressive and divide that by 4. For example we use 3 Austin Air HealthMate HEPA Air Purifier for our 900 sq.ft. living space.
• Check the north side of your building for mold. If found pressure wash it off and if possible, apply substances to inhibit them coming back.
• Check for mushrooms in lawns etc. If found, remove them and treat where you found them.

Remember, all fungi are not the same. Antibacterial and Antifungal Activities of Spices [2017] does not mention this fungi. Additionally, some spices are known to have Fungal Contamination of some Common Spices [2022] and Fungi and aflatoxins associated with spices in the Sultanate of Oman [2002] which included cloves (often deem an antifungal).

Basic Information

A big group — some good and some bad.

• General Information: Saccharomycetaceae [ScienceDirect]
  • “It is the first discovered probiotic yeast. French researcher Boulard discovered this gram-positive yeast belonging to the Saccharomycetaceae family”
  • Candida species: the pathogen is a member
• Opportunistic Strains of Saccharomyces cerevisiae: A Potential Risk Sold in Food Products [2015]
  • ” According to numerous studies, Candida albicans and other Candida species are the most remarkable pathogenic fungi “
• Invasive Saccharomyces Infection: A Comprehensive Review [2005]
  • “S. boulardii accounted for 51.3% of fungemias and was exclusively isolated from blood. “
  • “Overall, S. cerevisiae clinical isolates exhibited low susceptibility to amphotericin B and azole derivatives. “
• Antifungal susceptibility profile of diferent yeasts isolates from wild animals, cow’s milk with subclinical mastitis and hospital environment [2018] provides an extensive table of which children are susceptible to different antifungals.

Unfortunately, Thorne does not provide more detail.
