Morgellons Fibers After Twenty Years: Reading the New Middelveen–Stricker Review

by
Morgellons Fiber Review After Twenty Years — source analysis of the new 2026 Middelveen–Stricker review.

A new review finally puts two decades of unpublished fiber data into the citable record. What it puts on the record — and how the publicity around it departs from the paper itself — deserves a careful read.

On July 31, 2026, Archives of Clinical and Biomedical Research published “The Cellular Origin of Morgellons Disease Fibers: A Twenty Year Odyssey” (Middelveen, Fesler, Stricker; ACBR 10(4):224–236, DOI 10.26502/acbr.50170529). It is a narrative review — the authors retracing the fiber-analysis literature from the 2004 Charles E. Holman Foundation fiber study through their own 2020 work — and it arrives with a stated mission: to consolidate the case that Morgellons fibers are human in origin, composed of keratin and collagen, produced by keratinocytes and fibroblasts, and in some cases identifiable as unusually small human hairs.

Same Name, Different Patients: Why Morgellons Studies Keep Contradicting Each Other

by
Patient advocate examining a microscope slide beside Morgellons research papers, illustrating conflicting study definitions.

Morgellons studies appear to reach opposite conclusions. The CDC-supported investigation identified ordinary environmental material and no common infectious cause. Filament-focused papers described biological structures associated with skin tissue and reported evidence of Borrelia. Psychiatric literature frequently classifies Morgellons as delusional infestation. These findings may conflict partly because the studies did not consistently examine the same patients, specimens or definition of Morgellons disease.

Every Morgellons investigation begins by deciding who qualifies as a case. That decision determines which patients enter the study, which materials are analyzed and what the results can reasonably establish. A population defined by self-reported fibers is not necessarily equivalent to one selected for filaments considered embedded in or projecting from tissue. A psychiatric referral population is different again.

This does not mean that every interpretation is equally supported. It means the evidence must be judged within the boundaries of each study. Until researchers establish reproducible diagnostic criteria and independent laboratories examine comparable specimens, the name “Morgellons” will continue to describe several overlapping—and potentially unrelated—clinical presentations.

Tick-Borne Relapsing Fever and Morgellons: Is Borrelia Bigger Than Lyme Disease?

by
Tick-borne relapsing fever and Morgellons research image showing skin under magnification with fine irregular fibers.

Tick-borne relapsing fever is part of the larger Borrelia story, and that matters for Morgellons disease. Most people who hear the word Borrelia think of Lyme disease, but Lyme disease is only one part of the picture. Research by Marianne Middelveen, Raphael Stricker, and colleagues raises an important question: what if the spirochetal discussion around Morgellons is bigger than classic Lyme disease alone?

This article is not saying every person with Morgellons has tick-borne relapsing fever. It is not saying every skin lesion, fiber, or chronic symptom comes from one infection. It is also not saying Bartonella is a proven tick-borne co-infection. The point is more careful: Morgellons research has reported evidence involving both Lyme-group Borrelia and relapsing-fever Borrelia, while newer Bartonella evidence shows why patients should be cautious about repeating unsupported tick-borne claims.

What the Public Needs to Know About Morgellons, Lyme Disease, and Science As a Morgellons patient who understands the research, there is nothing more disparaging than consuming media which fails to even mention Lyme Disease when discussing the topic of my skin condition. Lyme disease is a Borrelia bacteria, I was tested for Borrelia bacteria …

Morgellons Disease: A Closer Look at the New Mayo Clinic Study and How it Fails to Understand the Literature

· by
Case-file graphic reading "Fibers observed. Questions unanswered." reviewing the 2023 Mayo-affiliated Morgellons commentary — observed fibers, no stated Borrelia testing method, antipsychotic treatment, lost to follow-up.

Mayo Clinic Morgellons commentary deserves careful review because a 2023 Mayo-affiliated article described ulcerative skin lesions, observed fibers, “no sign” of Borrelia infection, antipsychotic treatment, and loss of follow-up — but left important questions about testing, fiber analysis, and diagnosis unanswered. That short summary matters because it captures the central controversy surrounding Morgellons disease. Patients …
