Long-Term Changes to the Microbiome, Blood Lipid Profiles and IL-6 in Female and Male Swedish Patients in Response to Bariatric Roux-en-Y Gastric Bypass.

Lipid metabolism dysregulation is a critical factor contributing to obesity. To counteract obesity-associated disorders, bariatric surgery is implemented as a very effective method. However, surgery such as Roux-en-Y gastric bypass (RYGB) is irreversible, resulting in life-long changes to the digestive tract.

Synergistic effect of haloduracin and chloramphenicol against clinically important Gram-positive bacteria.

The emergence of drug-resistant pathogens has triggered the search for more efficient antimicrobial agents and formulations for treatment of infections. In recent years, combination therapy has become one of the effective clinical practices in treating infections. The present study deals with the effect of haloduracin, a lantibiotic bateriocin and chloramphenicol against clinically important bacteria.

Prebiotic preferences of human lactobacilli strains in co-culture with bifidobacteria and antimicrobial activity against Clostridium difficile.

Aim: To evaluate robustness, prebiotic utilization of Lactobacillus paracasei F8 and Lactobacillus plantarum F44 in mono- and co-cultures with Bifidobacterium breve 46 and Bifidobacterium animalis sub sp. lactis 8 : 8 and antimicrobial activity of co-culture against Clostridium difficile.

Methods And Results: The two Lactobacillus strains showed a high acid and bile tolerance.

A novel multi-strain probiotic and synbiotic supplement for prevention of Clostridium difficile infection in a murine model.

The protective effect of a multi-strain probiotic and synbiotic formulation was evaluated in C57BL/6 mice infected with Clostridium difficile (CD) NAP1/027. Antibiotic-treated mice were divided into the following four groups: Group 1, fed with a synbiotic formulation consisting of Lactobacillus plantarum F44, L. paracasei F8, Bifidobacterium breve 46, B.

Survival and synergistic growth of mixed cultures of bifidobacteria and lactobacilli combined with prebiotic oligosaccharides in a gastrointestinal tract simulator.

Background: Probiotics, especially in combination with non-digestible oligosaccharides, may balance the gut microflora while multistrain preparations may express an improved functionality over single strain cultures. In vitro gastrointestinal models enable to test survival and growth dynamics of mixed strain probiotics in a controlled, replicable manner.

Methods: The robustness and compatibility of multistrain probiotics composed of bifidobacteria and lactobacilli combined with mixed prebiotics (galacto-, fructo- and xylo-oligosaccharides or galactooligosaccharides and soluble starch) were studied using a dynamic gastrointestinal tract simulator (GITS).
