Background: Probiotic formulations can be single- or multi-strain. Commercially, multi-strain preparations have been suggested to have improved functionality over single-strain cultures. Probiotics are often tested as single-strain preparations but may subsequently be commercially formulated as multi-strain products. Objective: The aim of this study was to determine what happens at the site of ...

objectives: probiotic approaches are being considered to eliminate pathogenic microorganisms and are an alternative and promising way to combat infections by using harmless bacteria to displace pathogenic microorganisms. the aim of this study was to evaluate the effectiveness of commercially available freeze dried powdered probiotics on mutans streptococci count among 12-15 year-old indian scho...

AIMS To evaluate the effectiveness, safety and tolerability of a probiotic formulation containing Lactobacillus acidophilus LA-5 and Bifidobacterium BB-12 in the prevention of antibiotic associated diarrhoea (AAD). METHODS AND MATERIAL A double-blind randomised placebo controlled multicentric trial was conducted in adults who were prescribed a seven-day course of oral antibiotic (either cefad...

Imbalance in the resident microbiota may promote the growth of opportunistic microorganisms, such as yeasts of Candida genus and the development of diseases, especially in aged people. This study evaluated whether the consumption of the probiotic Yakult LBz(®) (Lactobacillus casei and Bifidobacterium breve) was able to influence on the specific immunological response against Candida and on the ...

BACKGROUND The incidence of human Campylobacter jejuni infections is progressively increasing worldwide. Probiotic compounds might open up valuable tools to decrease pathogen burden and subsequent pro-inflammatory immune responses, but in vivo data are scarce. METHODS AND RESULTS Secondary abiotic mice generated by broad-spectrum antibiotic treatment were perorally challenged with the commerc...

Sir, Eradication therapies for Helicobacter pylori infection are not yet satisfactory, although many therapeutic strategies have been studied to improve the eradication rate for this infection. Children rarely have symptoms of this infection and, therefore, are a suitable group in which to assess therapies that are non-aggressive compared with those used for adults. 1 The use of probiotics in t...

Probiotics are microorganisms which confer health benefits upon application in sufficiently-high viable cell amounts. Probiotics are typically members of Lactobacillus and Bifidobacterium species commonly associated with human gastrointestinal tracts. In the recent past, there has been a rising interest in producing functional foods containing encapsulated probiotic bacteria. Recent studies hav...

A large number of commensal bacteria inhabit the intestinal tract, and interbacterial communication among gut microbiota is thought to occur. In order to analyze symbiotic relationships between probiotic strains and the gut microbiota, a ring with a membrane filter fitted to the bottom was used for in vitro investigations. Test strains comprising probiotic nitto strains (Lactobacillus acidophil...

​Background: Consumption of Lactobacillus paracasei Lpc-37 or Bifidobacterium lactis HN019 by 2-5-year-old children was found to reduce risk for diarrhoea and fever during the rainy season. Objective: Can changes in faecal short chain fatty acids (SCFAs) or branched chain fatty acids (BCFAs) explain the observed positive influence of probiotics and their role on nutritional status and diarrhoea...

BACKGROUND AND OBJECTIVES immune system alteration in irritable bowel syndrome (IBS) patients may be modulated by probiotics. We assessed the efficacy of some probiotic species in alleviating characteristic IBS symptoms. MATERIAL AND METHODS a meta-analysis of all identified randomized controlled trials comparing probiotics with placebo in treating IBS symptoms was performed with continuous d...
