Detection of SARS-CoV-2 from Patient Fecal Samples by Whole Genome Sequencing
Rapid improvement in Alzheimer’s disease symptoms following fecal microbiota transplantation
Rapid improvement in Alzheimer’s disease symptoms following fecal microbiota transplantation
SARS-CoV-2 has been detected not only in respiratory secretions, but also in stool collections. Here were sought to identify SARS-CoV-2 by enrichment NGS from fecal samples, and to utilize whole genome analysis to characterize SARS-CoV-2 mutational variations in COVID-19 patients.

Alzheimer’s disease (AD), the most common form of dementia, is a leading cause of death and a major cause of morbidity in older people.

Alzheimer’s disease (AD), the most common form of dementia, is a leading cause of death and a major cause of morbidity in older people. The disease is characterized by progressive memory loss, cognitive impairment, and the cerebral accumulation of amyloid-b peptide. Given the health and economic impacts of AD, treatments that target the underlying etiology of AD or modify the course of the disease are of significant interest. The gut microbiome has been increasingly implicated [...]

Toxigenic Clostridioides difficile infection (CDI) is the most common cause of nosocomial disease in the United States, however, its prevalence in the general population is poorly understood. In this study we sought to determine the presence of Clostridioides difficile colonizing a representative sample of 119 asymptomatic adult volunteers, 12 of which were physicians treating patients with CDI. Methods: Next generation sequencing (NGS) was performed on fecal samples from [...]

Pathogenic Clostridioides difficile (C. difficile) is the most common cause of nosocomial infection in the United States. However, the prevalence of C. difficile colonization in the general population is poorly understood. We sought to determine the presence and nature of various C. difficile strains colonizing a representative sample of 17 asymptomatic adult volunteers, consisting of 10 healthy and 7 stable Crohn's patients.

The validity of breath collection bags method in detecting Helicobacter pylori using the novel BreathID®Hp Lab System: a multicenter clinical study in 257 subjects
The BreathID®Hp urea breath test provides several advantages over other 13C breath analyzers for the detection of Helicobacter pylori. We evaluated the sensitivity and specificity of a new BreathID®Hp Lab System (Exalenz Bioscience Ltd, Israel), a 13C-urea breath test system using breath sampling bags that facilitates multiple testing in a multicenter international clinical study.

Parkinson’s Disease (PD) is a central nervous system movement disorder characterized by the formation of spherical protein deposits in the brain (Lewy bodies) and the development of spindle-like Lewy neurites in the body of the affected neuron. These start in the medulla oblongata and spread in a predictable pattern, resulting in [...]

How Globalization Changes the Microbiome
Sabine Hazan, MD, Series Editor
The digestive tract’s microbial ecosystem is tailored for specific geographic areas. Here we discuss how the rise of globalization has spurred a mass transition of the European and American microbiome worldwide, altering the unique digestive patterns and processes of other nations. We can partially attribute our global obesity epidemic [...]

Probiotic is a general term for live, nonpathogenic microorganisms, many of which exist in a symbiotic relationship within the normal human gut flora. Here we discuss their growth in popularity, their use in treating Gastrointestinal (GI) and non-GI medical conditions, and the data demonstrating their [...]

Throughout this series we have pointed to evidence of an increasingly complex understanding of the relationship between the gut, its commensal bacterial composition, and its link to various pathological states within different organ systems. Here we will briefly discuss the emerging research that [...]

A new, emerging paradigm suggests that the susceptibility, severity, and duration of some diseases, even some previously thought to be independent of microbial involvement, are mediated by a complex interplay of host and microbe genomes. Already, nearly 10 million different microbial genes have been isolated from the human gut. In this series, we aim to shed light on some of the most promising research to date that [...]

Simply and elegantly defined by Lynch and Pedersen in their December 2016 article in the New England Journal of Medicine, a microbiome is the collection of all genomes of microbes in an ecosystem. In the context of human beings and our health, it is the vastly diverse genetic information observable in the microbes colonizing the distal GI tract. Historically, the study of human microbiology has been one of a [...]
