Gut Symbiont Bacteroides fragilis Secretes a Eukaryotic-Like Ubiquitin Protein That Mediates Intraspecies Antagonism

open access: yesmBio, 2017
Human gut Bacteroides species produce different types of toxins that antagonize closely related members of the gut microbiota. Some are toxic effectors delivered by type VI secretion systems, and others are non-contact-dependent secreted antimicrobial ...

Harnessing bacterial extracellular vesicles for bone and cartilage organoids

open access: yesBMEMat, EarlyView.
This review presents bacterial extracellular vesicles (BEVs) as programmable bioactive regulators for bone and cartilage organoids by delivering functional cargos that modulate skeletal remodeling. It highlights key engineering strategies and future directions to advance next‐generation organoid models for bone aging related diseases.

Aggregation by fragilis and non-fragilis Bacteroides strains in vitro [PDF]

open access: yesJournal of Medical Microbiology, 1989
Bacteroides fragilis is associated with the formation of intra-abdominal abscesses, whereas other Bacteroides species are rarely involved. Since bacterial clumping may contribute to the survival of bacteria in the face of host defence mechanisms, the hypothesis has been put forward that differences in aggregation between fragilis and non-fragilis ...

In Vitro Evaluation of Propolis Effects on Bacteroides fragilis Toxin-mediated Inflammatory Pathways

open access: yesKorean Journal of Clinical Laboratory Science
Colorectal cancer (CRC) remains a significant global health concern because of its increasing incidence and mortality rates. Chronic intestinal inflammation is a critical driver in the pathogenesis of CRC, particularly in individuals with inflammatory ...

Oral and Fecal Microbial Dysbiosis as Non‐Invasive Diagnostic Biomarkers for Gastrointestinal Cancers: A Systematic Review and Meta‐Analysis of Diagnostic Accuracy

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Gastrointestinal (GI) cancers, including esophageal (EC), gastric (GC), and colorectal cancer (CRC), impose a substantial global burden, with early detection remaining crucial for improving patient outcomes. The oral and gut microbiota are increasingly implicated in cancer development and hold promise as sources of non‐invasive biomarkers ...

Characterization of a Multidrug-Resistant, Novel Bacteroides Genomospecies

open access: yesEmerging Infectious Diseases, 2015
Metronidazole- and carbapenem-resistant Bacteroides fragilis are rare in the United States. We isolated a multidrug-resistant anaerobe from the bloodstream and intraabdominal abscesses of a patient who had traveled to India.

Unlocking insights: Validating a comprehensive model for predicting spontaneous preterm delivery and microbial invasion in women facing preterm labor

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm labor is a multifactorial syndrome with diverse etiologies such as infection, inflammation, uteroplacental dysfunction, stress, and immune dysregulation. Identifying women at high risk remains a challenge, and multivariate prediction models have been developed to enhance risk stratification.

Bacteroides nordii and Bacteroides salyersiae Isolated from Post-operative Peritonitis Patients [PDF]

open access: yes, 2017
In this study, we report three cases in which two species of the Bacteroides fragilis group, 'Bacteroides nordii' and 'Bacteroides salyersiae', were isolated from peritoneal fluid cultures from post-operative peritonitis patients.
