Detection of the pediocin gene pedA in strains from human faeces by real-time PCR and characterization of Pediococcus acidilactici UVA1
BACKGROUND Bacteriocin-producing lactic acid bacteria are commonly used as natural protective cultures. Among them, strains of the genus Pediococcus are particularly interesting for their ability to produce pediocin, a broad spectrum antimicrobial peptide with a strong antagonistic activity against the food-borne pathogen Listeria monocytogenes. Furthermore, there is increasing interest in isol...
متن کاملComplete Genome Sequence of the Probiotic Bifidobacterium thermophilum Strain RBL67
Bifidobacterium thermophilum RBL67, an isolate from infant feces, exhibits bacteriocin-like antimicrobial activity against Listeria spp. and Salmonella spp. and protects HT29-MTX cells against Salmonella infection. Here, the complete genome sequence of the probiotic B. thermophilum strain RBL67 is presented.
متن کاملEffect of Bifidobacterium thermophilum RBL67 and fructo-oligosaccharides on the gut microbiota in Göttingen minipigs.
Modulating the gut microbiota via dietary interventions is a common strategy to enhance the natural defence mechanisms of the host. Several in vitro studies have highlighted the probiotic potential of Bifidobacterium thermophilum RBL67 (RBL67) selected for its anti-Salmonella effects. The present study aimed to investigate the impact of RBL67 alone and combined with fructo-oligosaccharides (FOS...
متن کاملStudy of the Ability of Bifidobacteria of Human Origin to Prevent and Treat Rotavirus Infection Using Colonic Cell and Mouse Models
Rotavirus is the leading cause of severe acute gastroenteritis among children worldwide. Despite effective vaccines, inexpensive alternatives such as probiotics are needed. The aim of this study was to assess the ability of probiotic candidate Bifidobacterium thermophilum RBL67 to inhibit rotavirus infection. Bacterial adhesion to intestinal cells and interference with viral attachment were eva...
متن کاملCharacterization of Potential Probiotic Lactic Acid Bacteria- Pediococcus acidilactici Ch-2 Isolated from Chuli- A Traditional Apricot Product of Himalayan Region for the Production of Novel Bioactive Compounds with Special Therapeutic Properties
Objectives: In the present study, Pediococcus acidilactici Ch-2 isolated from Chuli has been evaluated for its probiotic potential and its ability to produce bioactive compounds. Methodology: Isolation was done on MRS agar followed by the safety assessment of isolates. Isolates were screened on the basis of their antagonistic potential against pathogenic bacteria. Probiotic attributes of screen...
