Certain strains of lactobacilli have been reported to exert favorable effects on atopic dermatitis (AD). Jeotgal, a traditional Korean food, is a salted fermented seafood known to harbor many lactic acid bacteria. In the present study, two novel lactobacillus strains were isolated from Jeotgal, and their anti-AD effects were investigated. Lactobacilli isolated from Jeotgal were identified, acco...

BACKGROUND Rotavirus-induced diarrhea poses a worldwide medical problem in causing substantial morbidity and mortality among children in developing countries. We therefore developed a system for passive immunotherapy in which recombinant lactobacilli constitutively express neutralizing variable domain of llama heavy-chain (VHH) antibody fragments against rotavirus. METHODS VHH were expressed ...

AIMS The aim of the study was to assess the relationships between the remaining shelf-life (RSL) of cold-smoked salmon and various microbiological and physico-chemical parameters, using a multivariate data analysis in the form of stepwise forward multiple regression. METHODS AND RESULTS Thirteen batches of French cold-smoked salmon were analysed weekly during vacuum-packed storage at 5 degree...

BACKGROUND Lactobacilli are the dominant bacteria of the vaginal flora and possess antimicrobial properties that regulate other urogenital microbiota. Incomplete cure and recurrence of genitourinary infections lead to a shift in the local flora from a predominance of lactobacilli to coliform uropathogens. Use of Lactobacillus-containing probiotics to restore commensal vaginal flora has been pro...

High levels of Lactobacillus, the dominant genus of the healthy human vaginal microbiota, have been epidemiologically linked to a reduced risk of infection following exposure to the sexually transmitted pathogen Neisseria gonorrhoeae. In this work, a cell culture model of gonococcal infection was adapted to examine the effects of lactobacilli on gonococcal interactions with endometrial epitheli...

Lin Tao and Sylvia I. Pavlova Department of Oral Biology, College of Dentisoy, University of Illinois at Chicago, Chicago, IL Normally, lactobacilli are a dominant species in the vagina and play an important role in maintaining vaginal health by producing hydrogen peroxide and lactic acid to inhibit other bacteria, such as pathogenic anaerobes. When bacterial vaginosis occurs, however, vaginal ...

The innate defense system of the female mucosal genital tract involves a close and complex interaction among the healthy vaginal microbiota, different cells, and various proteins that protect the host from pathogens. Vaginal lactobacilli and lactoferrin represent two essential actors in the vaginal environment. Lactobacilli represent the dominant bacterial species able to prevent facultative an...

Lactobacilli are indigenous microbes of the stomach of rodents, with much lower numbers being present in mice fed a purified diet than in those fed a non-purified diet. We postulated that gastric emptying (GE) is responsible for the different colonisation levels of lactobacilli and tested this hypothesis in the present study. BALB/cCr Slc mice were fed either a non-purified diet or a purified d...

Lactobacilli have long been considered to be protective flora in the vagina. In this study, samples were taken from the lateral vaginal wall of 19 healthy women, and 58 strains of Lactobacillus spp. were isolated from 10 of these women. The identification results revealed that Lactobacillus gasseri was the predominant lactobacilli in healthy women. The amounts of lactic acid and hydrogen peroxi...

Kefir is fermented milk with a slightly acidic taste obtained by incubating milk with kefir grains. These grains are white or lightly yellow gelatinous masses characterized by irregular forms, constituted by a complex mixture of lactococci, homofermentative and heterofermentative lactobacilli, yeasts and acetic acid bacteria living in a strong and specific symbiosis. This complex microflora is ...
