Lactobacillus paracasei DUP 13076 demonstrates antagonistic effects against the foodborne pathogens Salmonella enterica serovars Enteritidis, Typhimurium, and Heidelberg in coculture and in vitro experiments. Here, we report the draft genome sequence of Lactobacillus paracasei DUP 13076, which has a circular chromosome of 3,048,314 bp and a G+C content of 46.3%.

The present study aimed at assessing the counts and species distribution of intestinal lactobacilli and exploring if the data are associated with BMI and blood glucose level in healthy adults and elderly persons. The BMI (P < 0·01), the level of fasting blood glucose (P < 0·001) and the total counts of lactobacilli (P < 0·01 by bacteriology; P < 0·001 by real-time PCR) were higher in the elderl...

The most recent trend in research on probiotic bacteria aims at the exploitation of bioactive bacterial compounds that are responsible for health-promoting effects and suitable for medical applications. Therefore, the main purpose of this study was to ascertain if the immunomodulatory effects of L. paracasei strains on dendritic cells (DCs) were caused by bacterial metabolites released in the c...

Studies showed that specific probiotics might provide therapeutic benefits in inflammatory bowel disease. However, a rigorous screening of new probiotics is needed to study possible adverse interactions with the host, particularly when intended for administration to individuals with certain health risks. In this context, the objective of this study was to investigate the role of three lactobaci...

BACKGROUND Microbial deprivation early in life can potentially influence immune mediated disease development such as allergy. The aims of this study were to investigate the influence of parental allergy on the infant gut colonization and associations between infant gut microbiota and allergic disease at five years of age. METHODS AND FINDINGS Fecal samples were collected from 58 infants, with...

The present study investigated the ability of Bifidobacterium animalis ssp. lactis (BB-12®) and Lactobacillus paracasei ssp. paracasei (L. casei 431®) to modulate the immune system using a vaccination model in healthy subjects. A randomised, double-blind, placebo-controlled, parallel-group study was conducted in 211 subjects (56 % females, mean age 33·2 (sd 13·1) years). Subjects consumed a min...

BACKGROUND Probiotics can modulate the immune system in healthy individuals and may help reduce symptoms related to respiratory infections. OBJECTIVE The objective of the study was to investigate the effect of the probiotic strain Lactobacillus paracasei subsp. paracasei, L. casei 431 (Chr. Hansen A/S) (hereafter, L. casei 431) on immune response to influenza vaccination and respiratory sympt...

Numerous in vitro and in vivo studies conducted using different probiotic micro-organisms have demonstrated their ability to interfere with the growth and virulence of a variety of enteropathogens. The reported beneficial effects of the use of probiotics to complement antibiotic therapy or prevent diarrhoea or gastrointestinal infection in infants have increased in recent years. In the present ...

The effectiveness of a probiotic formulation applied in human vagina depends on the possibility of adaptation of the beneficial microorganisms in this environment. The understanding of the interactions of potentially probiotic microorganisms with the vaginal fluid, which shows some specific physical and chemical properties, can help to the design of improved vaginal probiotic formulations. The ...
