No invasive methodology to produce a probiotic low humid apple snack with potential effect against Helicobacter pylori
2012
Abstract A probiotic low humid apple snack with potential effect against the infection caused by Helicobacter pylori has been developed from apple (cv. Granny Smith) and mandarin juice with a high microbial content of Lactobacillus salivarius spp . salivarius , by vacuum impregnation and hot air drying techniques. The moisture content reached in the final product (0.144 ± 0.012 g water · g sample - 1 ) ensured stability, and although the drying process affected the microbial content, the concentration in the final product (9.486 ± 0.013) × 10 7 CFU g dry sample - 1 ) was sufficient to confirm that with this procedure it is possible to obtain a stable probiotic fruit with a low moisture c…
Highlights on two decades with microbiota and inflammatory bowel disease from etiology to therapy
2023
Inflammatory Bowel diseases (IBDs) constitute a complex panel of disorders characterized with chronic inflammation affecting the alimentary canal along with extra intestinal manifestations. Its exact etiology is still unknown; however, it seems to be the result of uncharacterized environmental insults in the intestine and their immunological consequences along with dysbiosis, in genetically predisposed individuals. It was the main target of our team since 2002 to explore the etiology of IBD and the related role of bacteria. For almost two decades, our laboratory, among others, has been involved in the reciprocal interaction between the host gastrointestinal lining and the homing microbiota.…
Selection and integration of a new immunomodulatory probiotic strain in a food supplement
2012
Probiotics are live microorganisms that can act on the immune system at specific sites in the gastro-intestinal tract. From a technological point of view, the development of a dietary supplement containing viable and functional probiotics requires the control of the selection and production steps. In a first time, we have developed specific and sensitive screening tests to determine the ability of bacteria to be dried and the origin of its sensitivity. To develop these tests, we investigated the mechanisms involved during drying process. Thus, microorganisms simultaneously undergo osmotic stress and oxidative stress. Results show a strong impact of drying on the survival rate and immunomodu…
Probiotics in the prevention and treatment of atopic dermatitis
2020
The use of probiotic supplements might change the composition of the intestinal flora of children, subsequently modulating the immune system's reactivity. The effects of probiotic administration for the prevention/treatment of allergic diseases and atopic dermatitis, in particular, are still so controversial that no definitive recommendation can be made at this stage. Differences in strain specificity, timing, and length of administration all contribute to diversifying the conclusions of this review.

Probiotic properties of Brevibacillus brevis and its influence on sea bass (Dicentrarchus labrax) larval rearing
2012
Efficacy of Brevibacillus brevis strain and its influence on larval rearing of sea bass (Dicentrarchus labrax) were investigated in the present work. Biochemical analyses permit to identify this strain as B. brevis. This bacterium has an inhibitory effect against fish pathogenic bacteria, especially the genus of Vibrio. Enzymatic characterization revealed that B. brevis was lipase positive, amylase, lecithinase and caseinase negative. Adherence assays to abiotic surfaces and challenge test with Artemia larvae demonstrate that B. brevis was fairly adherent and play an important role in the enhancement of the protection of Artemia culture against pathogens. Treatment of sea bass larvae with B…
Bovine lactoferrin prevents invasive fungal infections in very low birth weight infants: a randomized controlled trial.
2011
Background: Lactoferrin is a mammalian milk glycoprotein involved in innate immunity. Recent data show that bovine lactoferrin (bLF) prevents late-onset sepsis in preterm very low birth weight (VLBW) neonates. Methods: This is a secondary analysis of data from a multicenter randomized controlled trial where preterm VLBW neonates randomly received bLF (100 mg/day; group A1), bLF + Lactobacillus rhamnosus GG (106 colony-forming units per day; group A2), or placebo (group B) for 6 weeks. Here we analyze the incidence rates of fungal colonization, invasive fungal infection (IFI), and rate of progression from colonization to infection in all groups. Results: This study included 472 neonates who…
Dextransucrase Expression Is Concomitant with that of Replication and Maintenance Functions of the pMN1 Plasmid in
2017
The exopolysaccharide synthesized by Lactobacillus sakei MN1 is a dextran with antiviral and immunomodulatory properties of potential utility in aquaculture. In this work we have investigated the genetic basis of dextran production by this bacterium. Southern blot hybridization experiments demonstrated the plasmidic location of the dsrLS gene, which encodes the dextransucrase involved in dextran synthesis. DNA sequencing of the 11,126 kbp plasmid (pMN1) revealed that it belongs to a family which replicates by the theta mechanism, whose prototype is pUCL287. The plasmid comprises the origin of replication, repA, repB, and dsrLS genes, as well as seven open reading frames of uncharacterized f…
Randomized, placebo-controlled, double-blind and open-label studies in the treatment and prevention of acute diarrhea with Enterococcus faecium SF68
2020
Enterococcus faecium SF68® (SF68) is a licensed pharmaceutical for treatment and prevention of diarrhea in Austria, Italy and Switzerland. However, as for other probiotics, evidence for its efficacy is based on small to medium-sized studies. Four unpublished studies on the treatment of acute diarrhea and the prevention of antibiotic-associated diarrhea were analyzed: one randomized, double blind, placebo-controlled trial (RCT) for treatment (n = 1,143), one open-label study for treatment (n = 5,093), one RCT for prevention (n = 1,397) and one open-label study for prevention (n = 4,340). Patients in the treatment-arm and the open-label studies received SF68 (b.i.d. for the prevention studies…
Postoperative maintenance therapy for inflammatory bowel disease.
2006
. Curr Opin Gastroenterol. 2006 Jul;22(4):377-81. Postoperative maintenance therapy for inflammatory bowel disease. Cottone M, Orlando A, Modesto I. Department of General Medicine, Pneumology and Nutrition Clinic, Palermo University, Palermo, Italy. PURPOSE OF REVIEW: This review will highlight the knowledge gained from studies published in the year 2005 on maintenance treatment after surgery for inflammatory bowel diseases. RECENT FINDINGS: In Crohn's disease the role of smoking in increasing the risk of relapse and recurrence after surgery is confirmed. Ornidazole seems effective in reducing endoscopic recurrence and clinical relapse after surgery. Probiotics do not appear to be effective…
