Resistance of Bifidobacteria Toward Antibiotics
2021The genus Bifidobacterium constitutes one of the main groups of the human microbiota and some species have a long history of safe consumption supporting an excellent safety record. However, in the context of the increasing worldwide problems associate to the rise of pathogenic microorganisms with acquired resistance to antibiotics, the risk associated ...

Survival of bifidobacteria administered to calves
Folia Microbiologica, 2010Twenty-five bifidobacteria were isolated from feces of calves. Isolates were identified, and their functional properties and antimicrobial activity were determined. From 10 strains with suitable properties rifampicin-resistant mutants (RRBs) were prepared and mixture of RRBs was administered to 2-d-old calves.

Identification of Bifidobacteria by the Phosphoketolase Assay
2021Bifidobacteria are commensal bacteria, which naturally colonize the gastrointestinal tract of a large number of animals, including humans, contributing to their health and well-being. An important taxonomic marker for the identification of members of the bifidobacterial group is the presence of the fructose-6-phosphate phosphoketolase (F6PPK) activity.

Bifidobacteria in the digestive tract of bumblebees
Anaerobe, 2010Bifidobacteria and other bacterial groups (lactobacilli, facultative anaerobes, anaerobes) from the digestive tract of three bumblebee species (Bombus lucorum (34 samples), Bombus pascuorum (18 samples) and Bombus lapidarius (9 samples)) were enumerated and characterised. Counts of facultative anaerobic bacteria and lactobacilli (5.41+/-2.92 and 2.69+/-

Classification of Bifidobacteria
2020Bifidobacteria are Gram-positive, strictly anaerobic rods, which do not reduce nitrate; are nonspore-forming; do not produce catalase; and can ferment lactose, glucose, galactose, and fructose with the production of acetic and lactic acids in an approximate ratio of 1.5:1 without the evolution of gas.

Bifidobacteria have characteristic morphology, physiology, biochemical characteristics, cell-wall constituents, and DNA (deoxyribonucleic acid) base composition. They are found in the intestinal tract of human infants and adults, in the human vagina and mouth, and in the alimentary tracts of various animals.

Electroporation of bifidobacteria
2000Bifidobacterium represents one of the most numerous bacterial genera in the gut of humans and other animals and plays a fundamental role in the health of the host. In view of the development of bifidobacteria probiotic strains with improved characteristics, there is considerable interest in their manipulation using genetic engineering techniques.
