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 ...

Journal of Parenteral and Enteral Nutrition, EarlyView.Abstract The first 1000 days of life represent a critical window for gut microbiome assembly, with lifelong implications for child growth, immune development, and disease risk. This review synthesizes evidence on maternal, perinatal, and especially nutritional factors that influence early‐life intestinal colonization and highlights the consequences of ...

Requirement of heme for growth of Bacteroides fragilis [PDF]
Applied and Environmental Microbiology, 1977 Heme or protoporphyrin IX was required for growth of Bacteroides fragilis in a defined medium. The amount of heme necessary for half-maximal growth was 2 to 10 ng/ml (3.8 to 15 pmol/ml) among the Bacteroides species and strains tested. The growth rate, metabolic products from glucose fermentation, and cell yields were affected by the concentration of ...

Organoid Coculture Models for Cancer Research and Immunotherapy
Med Research, EarlyView.This review summarizes organoid coculture platforms, including submerged Matrigel culture, air–liquid interface, microfluidic/organoid‐on‐a‐chip, and 3D bioprinting, for reconstructing the tumor microenvironment to study tumor–stroma/immune crosstalk, evaluate immunotherapies, and enable drug screening.

Fecal detection of enterotoxigenic Bacteroides fragilis [PDF]
European Journal of Clinical Microbiology & Infectious Diseases, 2015 Bacteroides fragilis is a common colonic symbiote of which one subtype, enterotoxigenic Bacteroides fragilis (ETBF), causes inflammatory diarrhea. However, asymptomatic ETBF colonization is common. Through its primary virulence factor, B. fragilis toxin (BFT), ETBF causes asymptomatic, chronic colitis in C57BL/6 mice and increased colon tumorigenesis ...

Catechins and Their Effect on the Gut Microbiome in Health and Cancer
Phytotherapy Research, EarlyView.ABSTRACT Catechins are a group of flavonoids found primarily in green tea, fruits, and berries; they play a significant role in the modulation of the gut microbiota, thereby having an impact on gut health and cancer prevention. Owing to their low bioavailability, catechins are transformed by the gut microbiota into various bioactive metabolites such as
