Lactobacillus paracasei is a member of the normal human and animal gut microbiota and is used extensively in the food industry in starter cultures for dairy products or as probiotics. With the development of low-cost, high-throughput sequencing techniques it has become feasible to sequence many different strains of one species and to determine its "pan-genome". We have sequenced the genomes of ...

Lactic acid bacteria are very significant to human health due to the production of some antimicrobial substances and ability to inhibit pathogenic bacteria. In this study, Lactobacillus strains were isolated from yogurts of Khulna region, Bangladesh and identified as Lactobacillus paracasei ssp. paracasei-1. The antimicrobial activity of cell free supernatant was tested against both gram positi...

Irritable Bowel Syndrome (IBS) is a common multifactorial intestinal disorder for which the aetiology remains largely undefined. Here, we have used a Trichinella spiralis (T. spiralis)-induced model of post-infective IBS, and the effects of probiotic bacteria on gut dysfunction have been investigated using a metabonomic strategy. A total of 44 mice were divided into four groups: an uninfected c...

AIMS This study aimed to determine the effect of a cell-free supernatant of Lactobacillus paracasei ATCC 27092 with and without rice bran extract (RBE) on Salmonella Typhimurium 14028s growth, and to identify a metabolite profile with antimicrobial functions. METHODS AND RESULTS Supernatant was collected from overnight cultures of L. paracasei incubated in the presence (LP+RBE) or absence (LP...

Exendin-4, a glucagon-like protein-1 (GLP-1) receptor agonist, is an excellent therapeutic peptide drug for type 2 diabetes due to longer lasting biological activity compared to GLP-1. This study explored the feasibility of using probiotic Lactobacillus paracasei as an oral vector for recombinant exendin-4 peptide delivery, an alternative to costly chemical synthesis and inconvenient administra...

BACKGROUND While the use of probiotics to treat or prevent inflammatory bowel disease (IBD) has been proposed, to this point the clinical benefits have been limited. In this report we analyzed the immunological activity of three strains of Lactobacillus to predict their in vivo efficacy in protecting against experimental colitis. METHODOLOGY/PRINCIPAL FINDINGS We compared the immunological pr...

Background: Bacteriocins are small peptides which are ribosomally synthesized and have been shown to have wide range of antimicrobial activity. The aim of this study was to optimize the production of L. paracasei MG847589 bacteriocin. Furthermore, the potential antibacterial properties of the novel bacteriocins were characterized and evaluated against Staphylococcus aureus. Methods: The presen...

CHARACTERISTICS OF THE SPECIES Lactobacillus paracasei is a Gram-positive, non-spore forming, homofermentative rod that is a common inhabitant of the human intestinal tract (1,2). L. paracasei strains are also found naturally in fermented vegetables, milk and meat. Strains of this species are used in many food products, including traditional fermented milks and cheese. Selected strains of this ...

Probiotics could represent an effective alternative to the use of synthetic substances in nutrition and medicine. The data concerning the efficacy of probiotics are often contradictory. This paper focuses on the enhancement of the efficacy of probiotics by their combination with synergistically acting components of natural origin. Maltodextrins can be obtained by enzymatic hydrolysis of starch ...

Reducing the burden of pathogenic mutans streptococci is a goal of oral health. Lactobacillus paracasei DSMZ16671, even after heat-killing, specifically co-aggregates mutans streptococci in vitro and retains this activity in human saliva. In rats, it reduces mutans streptococcal colonization of teeth and caries scores. This pilot study sought to assess the potential of heat-killed L. paracasei ...
