Gene-microbiota interactions contribute to the pathogenesis of inflammatory bowel disease [PDF]

, 2016
Inflammatory bowel disease (IBD) is associated with risk variants in the human genome and dysbiosis of the gut microbiome, though unifying principles for these findings remain largely undescribed.

Phylosymbiosis and Parallel Geographical Patterns in the Gut Microbiota of Desert‐Dwelling Amphibians and Reptiles

Integrative Zoology, EarlyView.
Host species emerge as a significant contributor to interspecies variations in the gut microbiota of desert‐dwelling amphibians and reptiles, illustrating phylosymbiosis among the studied species. Geographical factors partially account for interpopulation variations in the gut microbiota of Bufotes pewzowi and Teratoscincus przewalskii, with parallel ...

NOVEL APPROACH FOR EVALUATION OF BACTEROIDES FRAGILIS PROTECTIVE ROLE AGAINST BARTONELLA HENSELAE LIVER DAMAGE IN IMMUNOCOMPROMISED MURINE MODEL

Frontiers in Microbiology, 2016
Bartonella henselae is a gram-negative facultative intracellular bacterium and is the causative agent of cat scratch disease. Our previous data have established that Bacteroides fragilis colonization is able to prevent B.

In Vitro Activities of Tigecycline against the Bacteroides fragilis Group [PDF]

Antimicrobial Agents and Chemotherapy, 2004
ABSTRACT The in vitro activities of tigecycline were tested against 831 isolates of the Bacteroides fragilis group representing all of the species within the group. On a weight-to-weight basis (8 μg/ml), tigecycline was more active than clindamycin, minocycline, trovafloxacin, and cefoxitin and less active

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Spinal epidural abscess caused by Bacteroides fragilis group after dilation and curettage for incomplete abortion

Journal of Global Infectious Diseases, 2012
Spinal epidural abscess (SEA) is a rare infection complicated in patients who have some risk factors such as injection-drug use, diabetes mellitus, and several illnesses. However, no case of SEA associated with abortion has been reported.

Virulence factors in Bacteroides fragilis group.

The Indian journal of medical research, 1992
Attempts were made to study the virulence factors in some strains of B. fragilis group in the rat model. Subcutaneous wound abscesses could be produced by 10(9) CFU/ml of live cells of all the five species of B. fragilis group tested. For determination of virulence factor cellular components (capsular polysaccharide and lipopolysaccharide) of B ...
