Parkison’s and the Gut: An Update

I haven’t given you a Parkinson’s-and-the-biome update in several months now, and as yesterday I read a great review of the current status of our knowledge on the connection between the two, I figured it was time.[i] I am sure that most of you…

The Promise of Helminths for Multiple Sclerosis

Today I get to write about something other than the bacterial microbiome!  Woopa! I was very happy to find a new paper on the possibilities of using helminths (helminth immunotherapy (HIT), as these authors call it) to prevent and alleviate multiple sclerosis (MS).[i]  …

Early Life Stress, the Microbiome and Children’s Behavior

Well, this will come as a complete shock to most of you.  (NOT)  The bacterial contents of children’s guts affects their behavior. One of the big biome stories of the last few days is that research out of Oregon State University and the University…

Another Means of Manipulating the Gut Bacteria to Prevent MS?

Today’s a post is a shout-out to all you fans of Akkermansia muciniphila, which I’ve focused on in several posts in the past.   (For example, here and here, among others.) There were some pretty wild and amazing findings in a recent study out of…

The Microbiome and the Basal Ganglia in …The Case of the Leaky Gut?

I recently read an article looking at the effects of bacterial microbiome alterations on particular circuits in the brain (the thalamo-cortico-basal ganglia)  that are associated with compulsive behavior, addiction, altered sensations and motor output.[i]  What struck me is how closely related seemingly unrelated disorders…

Fecal Microbiota Transplant: the Answer for Alzheimer’s Disease?

Ok, yeah…more on fecal microbiota transplants (FMT).  This is my obsession for the week. But after reading my last post…can you blame me?! In that post, in case you missed it, I talked about a new article reviewing the potential of FMT to treat…

Probiotics for Chronic Fatigue and Fibromyalgia? Probably, but the Science Isn’t Yet There

As regular readers know, I’m always on the lookout for “things you can do now.”  I’m especially happy then when actual clinical trials happen as we can get some idea of the effectiveness of treatments.  About 18 months ago, a paper was published reviewing…

Ameliorating the Adverse Effects of Excess Propionic Acid

I am officially declaring this Biome Buzz’ first annual Propionic Acid Week! (Unfortunately, this is not a cause for celebration.) If you remember, propionic acid (PPA) is a short-chain fatty acid produced by gut bacteria.  Ordinarily, PPA , like the other SCFAs, is great…

Is There Any Doubt Left that Propionic Acid is a Cause of Autism? Apparently not

I first started to write about autism and propionic acid (PPA) not long after creating this blog, back in the fall of 2016.  In January 2017, I described to you some of the work of Dr. Derrick MacFabe, which as particularly fascinated me for…

The Two Sides of Bacteroides fragilis

Back in May, 2018, I wrote about Bacteriodes fragilis (B. fragilis), a species of bacteria some strains of which are toxic, some of which are highly beneficial.  The main thrust of that post was about how our immune system, when functioning properly, can recognize…
