About

Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease—four years before the first published case study.

Retrograde Menstruation Theory

Retrograde menstruation theory holds that during menstruation, some endometrial tissue reverses through the fallopian tubes into the pelvic cavity. It implants on pelvic organs, thickens, breaks down, and bleeds cyclically, causing inflammation, pain, and scar tissue, characteristic of endometriosis.

Molecular Mimicry

Definition Molecular mimicry is a biological phenomenon where the molecules (usually proteins or peptides) of one organism mimic the molecular structures of another organism. This mimicry can occur between molecules of different viruses, between viruses and the host, or between different cellular components within an organism.Fundamental Molecules: At the most basic level, molecular mimicry involves […]

Virulence Factors

Virulence factors are molecules produced by pathogens that contribute to their ability to infect, colonize, and cause disease in host organisms by evading the immune system or damaging host tissues.

Dimethylglyoxime (DMG)

Dimethylglyoxime (MG) is a chemical compound known for its ability to selectively chelate Nickel ions (Ni^2+), forming a bright red precipitate. This property has made MG a useful reagent in analytical chemistry for detecting and quantifying nickel. In fighting pathogens with nickel-dependent enzymes, such as those possessing urease or hydrogenase essential for their survival and […]

Low‑Nickel Diet (LNiD)

A low-nickel diet (NiD) is a therapeutic dietary intervention that eliminates high-nickel foods, primarily plant-based sources such as legumes, nuts, whole grains, and cocoa, to reduce systemic nickel exposure. It is clinically validated for managing systemic nickel allergy syndrome (NAS) and nickel-induced eczema. Its relevance is well-established in microbiome modulation, with studies demonstrating clinical benefits in conditions such as endometriosis, fibromyalgia, irritable bowel syndrome, and ERD.
