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

Journal 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.

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

iMetaMed, EarlyView.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

Characterization of a Multidrug-Resistant, Novel Bacteroides Genomospecies

Emerging 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.

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Superoxide dismutase in Bacteroides fragilis and related Bacteroides species [PDF]

Journal of Clinical Microbiology, 1977
Superoxide dismutase (SOD) activity was demonstrated in cell-free extracts of Bacteroides fragilis, Bacteroides vulgatus, Bacteroides distasonis, Bacteroides ovatus, and Bacteroides thetaiotaomicron. The strains were grown under anaerobic conditions in Trypticase soy broth, and the specific activity of SOD in the extracts was, in most strains, higher ...

Microbiome—pancreatic cancer crosstalk: From tumor biology to therapeutic intervention

iMetaOmics, EarlyView.
The intratumoral microbiome acts as a critical regulator in pancreatic cancer progression and therapeutic resistance. This comprehensive review delineates the origins of pancreatic microbes, elucidates their multifaceted mechanisms in driving immune suppression, metabolic reprogramming, and stromal desmoplasia, and highlights the clinical potential of ...

The role of human microbiota in breast cancer pathogenesis and treatment

iMeta, EarlyView.
The human microbiota contributes to breast cancer pathogenesis and treatment response through interactions involving the oral, gut, and breast microbial niches. (Left) Multi‐site dysbiosis is characterized by altered microbial composition and abundance across different anatomical sites.

Maternal and infant gut microbiome

iMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Serological studies ofBacteroides fragilis [PDF]

Journal of Hygiene, 1977
SUMMARYUsing direct agglutination methods, a simple serological scheme for the classification ofBacteroides fragilisis described. Twenty strains ofB. fragiliswere selected by a process of successive screening from 151 strains obtained from various sources.

Macrophage extracellular vesicles deliver Mef2d proteins to aggravate Bacteroides fragilis pathogenicity in type 2 diabetes arterial calcification

Interdisciplinary Medicine, EarlyView.
Bacteroides fragilis is associated with type 2 diabetes (T2D) arterial calcification and can be activated by macrophage‐derived extracellular vesicles (EVs). BF takes up EVs via receptor‐mediated endocytosis, and activation is induced by EV‐derived Mef2d, thereby inhibiting ArsR family transcriptional regulator transcription.
