As probiotics in the gut, Lactobacilli are believed to play important roles in the development and maintenance of both the mucosal and systemic immune system of the host. This study was aimed to investigate the immuno-modulatory function of candiate lactobacilli on T cells. Lactobacilli were isolated from healthy human feces and the microbiological characteristics were identified by API 50 CHL ...

Lactobacilli belong to the genus Lactobacillus, the largest genus among the lactic acid bacteria (LAB). They are abundant in plant material and food resources, or they may inhabit niches in or on the bodies of humans and animals, as commensals. Lactobacilli of food origin are commercially important in the production of dairy products, fermented meats, vegetables, and sourdough, and many of thei...

BACKGROUND & OBJECTIVE Lactobacilli are depleted in vagina of women suffering from recurring episodes of bacterial vaginosis with vaginal pH >or=5. With the objective of making available probiotic lactobacilli for replenishment in such women, a study was undertaken to isolate and characterize the Lactobacilli present in women with eco-healthy vagina in Delhi. No information is so far available ...

in the recent years, herbal oral hygiene products have gained increasing attention. the aim of this study was to assess the effects of three types of mastic gums on the level of mutans streptococci, lactobacilli and ph of the saliva.forty-two students in the age range of 20-30 years were divided into three parallel groups; each of them separately used pure mastic gum, xylitol mastic gum and pro...

Effects of chemical structure, concentration, and pH on antimicrobial activity conjugated bile acids were investigated in 4 strains lactobacilli. Considerable differences observed the between 6 human acids, including glycocholic acid, taurocholic glycodeoxycholic taurodeoxycholic glycochenodeoxycholic taurochenodeoxycholic acid. Glycodeoxycholic acid generally showed significantly higher agains...

AIMS This study investigates the dynamics of the microflora, particularly the lactobacilli, in Cheddar cheese manufactured from raw and microfiltered milk containing different adjunct cultures. METHODS AND RESULTS Sixteen cheeses - raw milk, adjunct and control cheeses - were manufactured in four trials. Lactobacilli were identified by PCR methods in one trial, and by phenotypic typing for al...

OBJECTIVE To determine the effect of estrogen replacement therapy (ERT) on the vaginal flora of postmenopausal women. METHODS Vaginal cultures were obtained from 15 postmenopausal women whose hormonal statuses were documented by serum follicle-stimulating hormone (FSH) and serum estrogen levels. After 8 weeks of ERT, consisting of 0.1 mg of estradiol delivered daily by dermal patch, the vagin...

As honey bee populations decline, interest in pathogenic and mutualistic relationships between bees and microorganisms has increased. Honey bees and bumble bees appear to have a simple intestinal bacterial fauna that includes acidophilic bacteria. Here, we explore the hypothesis that sweat bees can acquire acidophilic bacteria from the environment. To quantify bacterial communities associated w...

H2O2-producing lactobacilli in the vaginal fluid have been suggested to play a potential tumor-preventive role in addition to the control of undesirable microorganisms. As the vaginal fluid also contains a significant concentration of peroxidase that might utilize lactobacilli-derived H2O2 as substrate for HOCl synthesis, a dominant biological role of HOCl in both natural defence systems has be...

AIMS This study investigates the antagonistic effects of the probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 against vulvovaginal candidiasis (VVC)-causing Candida glabrata. METHODS AND RESULTS Growth inhibitory activities of Lact. rhamnosus GR-1 and Lact. reuteri RC-14 strains against C. glabrata were demonstrated using a spot overlay assay and a plate-based mi...
