Bifidobacterium strains from resident infant human gastrointestinal microflora exert antimicrobial activity.
BACKGROUND AND AIMS The gastrointestinal microflora exerts a barrier effect against enteropathogens. The aim of this study was to examine if bifidobacteria, a major species of the human colonic microflora, participates in the barrier effect by developing antimicrobial activity against enterovirulent bacteria. METHODS Antibacterial activity was examined in vitro against a wide range of Gram ne...
متن کاملAntimicrobial activity of a novel adhesive containing chlorhexidine gluconate (CHG) against the resident microflora in human volunteers
OBJECTIVES To evaluate the antimicrobial activity of a new, transparent composite film dressing, whose adhesive contains chlorhexidine gluconate (CHG), against the native microflora present on human skin. METHODS CHG-containing adhesive film dressings and non-antimicrobial control film dressings were applied to the skin on the backs of healthy human volunteers without antiseptic preparation. ...
متن کاملVariation in consumption of human milk oligosaccharides by infant gut-associated strains of Bifidobacterium breve.
Human milk contains a high concentration of complex oligosaccharides that influence the composition of the intestinal microbiota in breast-fed infants. Previous studies have indicated that select species such as Bifidobacterium longum subsp. infantis and Bifidobacterium bifidum can utilize human milk oligosaccharides (HMO) in vitro as the sole carbon source, while the relatively few B. longum s...
متن کاملAntimicrobial susceptibility of Bifidobacterium strains from humans, animals and probiotic products.
OBJECTIVES The aim of this study was to assess the antimicrobial susceptibility of a taxonomically diverse set of Bifidobacterium strains to different classes of antimicrobial agents using a recently described medium. METHODS The susceptibility of 100 strains encompassing 11 bifidobacterial species originating from humans, animals and probiotic products to 12 antimicrobial agents was tested b...
متن کاملAntimicrobial susceptibility of Bifidobacterium.
The susceptibility pattern of 459 strains of bifidobacteria, representing 15 species, to 16 antimicrobial agents was determined by the broth dilution method. The majority of the strains derived from human faeces. Penicillin G, erythromycin, clindamycin, vancomycin and bacitracin were the most active compounds; they inhibited 90% of the strains at less than 1.6 micrograms/ml. All strains were su...
