BACKGROUND The probiotic microorganisms are live normal flora that provide nutritional benefits. When probiotic administered in adequate amounts, they also confer a health benefit on the host. Different mechanisms of probiotic effects include the following: stimulating the immune system, modifying the composition of normal intestinal flora and preventing the carcinogenic activity of fecal enzym...

Lactobacilli were found in saliva, on teeth, and on the dorsum of the tongue, the vestibular mucosa, and the hard palate in humans. Their proportions in saliva, expressed as percentage of the anaerobically cultivable flora, were 10- to 100-fold higher than those on the tooth surface, but were comparable to those on the epithelial surfaces. The adherence of Lactobacillus casei and L. fermenti to...

AIMS The aims of this study were to evaluate the ability of exogenous Lactobacillus acidophilus strain NCFM to survive through the human gastro-intestinal (GI) tract, and to evaluate the selectivity of Rogosa SL medium for faecal lactobacilli. METHODS AND RESULTS The composition of the faecal lactobacilli of 10 healthy subjects was monitored for two weeks prior to, two weeks during and two we...

BACKGROUND Lactobacilli are used in an attempt to maintain remission for Crohn disease. The aim of this study was to evaluate the efficacy and adverse events of Lactobacilli compared with placebo in maintenance therapy for Crohn disease. METHODS We searched MEDLINE, EMBASE, the Cochrane Controlled Trials Register, OVID and BIOSIS. All randomized trials comparing Lactobacilli with placebo in m...

Fermented milk products have been used therapeutically in the ancient systems of medicine in the Near and Middle East for centuries. However, the nutritional and therapeutic value of lactic acid organisms is still controversial. Several preclinical and clinical studies have been performed, showing that fermentation of food with lactobacilli increases the quantity, availability, digestibility an...

OBJECTIVE Bacterial vaginosis (BV) is characterized by a shift in vaginal tract ecology, which includes a decrease in the concentration and/or prevalence of facultative lactobacilli. Currently, mechanisms which could account for the disappearance of lactobacilli are not well understood. The objective of this study was to determine whether vaginal streptococci/enterococci can produce bacteriocin...

INTRODUCTION Intestinal lactobacilli have been successfully used as probiotics to treat gastrointestinal disorders, but only limited data are available for the probiotic properties of oral lactobacilli to combat oral diseases. We aimed to characterize oral lactobacilli for their potential probiotic properties according to the international guidelines for the evaluation of probiotics, and to sel...

normal 0 false false false en-us x-none ar-sa background : the beneficial effects of lactobacillus species have been reported but the role of these species including lactobacillus casei (l.casei) on oral health is not well documented. the purpose of this study was to evaluate the effects of conventional or probiotic cheese containing l.casei on salivary streptococcus mutans (sm) and lactobacill...

Amid trends in non-dairy probiotic foods and functional coffees, it is timely to develop a high-count probiotic, fermented coffee beverage. Here, we aimed enhance the viabilities of different lactobacilli strains brews by co-culturing with yeast, Saccharomyces boulardii CNCM-I745. The growth, survival, metabolic activities Lactiplantibacillus plantarum 299v, Lactobacillus acidophilus NCFM, Limo...

A combination of denaturing gradient gel electrophoresis (DGGE) and a previously described multiplex PCR approach was employed to detect sourdough lactobacilli. Primers specific for certain groups of Lactobacillus spp. were used to amplify fragments, which were analyzed by DGGE. DGGE profiles obtained from Lactobacillus type strains acted as standards to analyze lactobacilli from four regional ...
