Anaerobic utilization of Fe(III)‐xenosiderophores among Bacteroides species and the distinct assimilation of Fe(III)‐ferrichrome by Bacteroides fragilis within the genus

open access: yesMicrobiologyOpen, 2017
In this study, we show that Bacteroides species utilize Fe(III)‐xenosiderophores as the only source of exogenous iron to support growth under iron‐limiting conditions in vitro anaerobically.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Serogrouping of Bacteroides fragilis subsp. fragilis by the agglutination test [PDF]

open access: yesJournal of Clinical Microbiology, 1976
The agglutination technique was used to establish a serological classification scheme for 98 strains of Bacteroides fragilis subsp. fragilis isolated from clinical specimens and normal human feces. Absorbed antisera were prepared to seven strains of B. fragilis subsp. fragilis.

Crystal structure of the Large Type III Glutamine Synthetase from Bacteroides Fragilis [PDF]

open access: yes, 2010
Glutamine synthetases are one of the most ancient functioning enzymes in existence and these large oligomeric complexes are found in all extant forms of life where they play a critical role in nitrogen metabolism.

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

open access: yesMolecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

Gut Microbial Topology and Metabolic Signatures Associated With Colorectal Neoplasia

open access: yesAdvanced Science, EarlyView.
The gut microbiota organizes into two robust association patterns linked to colorectal neoplasia risk. Topological shifts in microbial networks are associated with metabolite alterations and may shape host responses during disease development. ABSTRACT Alterations of gut microbial communities impact health.

From pathogen to “living drug factory” innovative strategies and clinical translation of bacteria as programmable intelligent vectors for cancer therapy

open access: yesBMEMat, EarlyView.
Engineered bacteria serve as smart, living therapeutics that target tumors, deliver drugs, and remodel immunosuppressive microenvironments. This review highlights their potential to potentiate immunotherapy, radiotherapy, and chemotherapy, offering a promising paradigm for precise and synergistic cancer treatment. Abstract The dynamic interplay between
