Bacteroides Fragilis in the gut microbiomes of Alzheimer’s disease activates microglia and triggers pathogenesis in neuronal C/EBPβ transgenic mice

Nature Communications, 2023
Gut dysbiosis contributes to Alzheimer’s disease (AD) pathogenesis, and Bacteroides strains are selectively elevated in AD gut microbiota. However, it remains unknown which Bacteroides species and how their metabolites trigger AD pathologies.

Bacteroides fragilis meningitis [PDF]

Journal of Clinical Microbiology, 1985
A fatal case of pyogenic meningitis due to Bacteroides fragilis in a 6-year-old boy is reported. The need for processing cerebrospinal fluid of patients with underlying conditions such as chronic otitis media for recovery of both aerobes and anaerobes is discussed.

Tetracycline transport in Bacteroides fragilis [PDF]

Antimicrobial Agents and Chemotherapy, 1980
In susceptible strain of Bacteroides fragilis, tetracycline uptake is biphasic. The initial phase is independent of adenosine 5'-triphosphate synthesis, which is coupled to fumarate reduction; this phase is not altered by expression of tetracycline resistance genes in a resistant strain.

Enterotoxigenic and nontoxigenic Bacteroides fragilis strains isolated in Brazil

Memorias do Instituto Oswaldo Cruz, 2008
The presence of enterotoxigenic Bacteroides fragilis and nontoxigenic B. fragilis (NTBF) among 109 strains isolated from 1980-2008 in Brazil were investigated by PCR.

Cefoxitin inactivation by Bacteroides fragilis [PDF]

Antimicrobial Agents and Chemotherapy, 1983
We have surveyed the susceptibility of 1,575 clinical isolates of the Bacteroides fragilis group of organisms to cefoxitin and eight other antimicrobial agents. Eleven isolates, 0.7% of the total, were highly cefoxitin resistant and had minimum inhibitory concentrations of greater than or equal to 64 micrograms/ml. These isolates were also resistant to

Intracellular Polysaccharide of Bacteroides fragilis [PDF]

Journal of General Microbiology, 1979
Formation of iodophilic polysaccharide (IPS) from glucose was demonstrated in 27 strains of Bacteroides fragilis. Synthesis was dependent on the glucose concentration of the medium, the pH and the growth phase. When glucose was in short supply the cellular polysaccharide was degraded rapidly at pH 4.5 to 6.5 and fatty acids accumulated in the medium ...

Radioimmunoassay for Bacteroides fragilis infections [PDF]

Journal of Clinical Microbiology, 1980
Radioimmunoassay methods were evaluated for immunoglobulin G and immunoglobulin M antibodies against Bacteroides fragilis antigen. Of 12 serum samples from patients with B fragilis infections, 9 had higher concentrations of immunoglobulin G antibodies than any from 11 control subjects.

Haemagglutination by the Bacteroides fragilis group [PDF]

Journal of Medical Microbiology, 1986
Adhesive properties of five species of Bacteroides were compared by direct haemagglutination with erythrocytes of different origin. Only strains of Bacteroides fragilis agglutinated erythrocytes and different patterns of haemagglutination were observed. None of eight carbohydrates tested inhibited haemagglutination.
