| pathogenic potential of lactobacilli. | lactobacilli are often considered to be commensal or beneficial participants in human microbial ecology and considerable research is being carried out into the effects of the use of lactobacilli as additives in both human and animal diets. however, lactobacilli also cause some human diseases (e.g. dental caries, rheumatic vascular disease, septicaemia and infective endocarditis (ie)), and have recently been identified as potential emerging pathogens in elderly and immunocompromised patients, par ... | 1994 | 7703012 |
| the aggregation of human platelets by lactobacillus species. | the ability to aggregate human platelets was examined for five lactobacillus rhamnosus strains and five lactobacillus paracasei subsp. paracasei strains isolated from patients with infective endocarditis (ie), 25 laboratory isolates from the same two species, and 14 strains from five other oral species, namely lactobacillus acidophilus, lactobacillus fermentum, lactobacillus oris, lactobacillus plantarum and lactobacillus salivarius. amongst the l. rhamnosus strains, platelets were aggregated by ... | 1993 | 8126421 |
| lactobacillus panis sp. nov., from sourdough with a long fermentation period. | two lactobacillus strains isolated from rye sourdough most closely resemble lactobacillus oris on the basis of their physiological, morphological, and chemotaxonomic characteristics. a 16s ribosomal dna sequence analysis showed that these two strains clustered with, but were separate from, l. oris, lactobacillus vaginalis, and lactobacillus pontis. the results of dna-dna hybridization experiments indicated that the new two isolates represent a new lactobacillus species, for which we propose the ... | 1996 | 8934903 |
| lactobacillus frumenti sp. nov., a new lactic acid bacterium isolated from rye-bran fermentations with a long fermentation period. | within the framework of the characterization of the microflora of an industrial sourdough fermentation, strains of lactobacillus amylovorus, lactobacillus pontis and two other strains were isolated which could not be associated with a valid species. these latter strains were gram-positive, catalase-negative, non-spore-forming, non-motile rods that could be clearly differentiated from known species by 16s rdna sequence analysis. for further characterization, the morphological, physiological (suga ... | 2000 | 11155988 |
| characterization of oral lactobacilli as potential probiotics for oral health. | 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 select potential probiotic strains for oral health. | 2008 | 18279182 |
| predominant genera of fecal microbiota in children with atopic dermatitis are not altered by intake of probiotic bacteria lactobacillus acidophilus ncfm and bifidobacterium animalis subsp. lactis bi-07. | the effect of probiotic bacteria lactobacillus acidophilus ncfm and bifidobacterium lactis bi-07 on the composition of the lactobacillus group, bifidobacterium and the total bacterial population in feces from young children with atopic dermatitis was investigated. the study included 50 children randomized to intake of one of the probiotic strain or placebo. microbial composition was characterized by denaturing gradient gel electrophoresis, quantitative pcr and, in a subset of subjects, by pyrose ... | 2011 | 21204871 |
| inhibitory effect of oral lactobacillus against oral pathogens. | aim: to determine the inhibitory effect of oral lactobacillus against putative oral pathogens. methods and results: total 357 strains comprising 10 species of oral lactobacillus, lactobacillus fermentum (195), lactobacillus salivarius (53), lactobacillus casei (20), lactobacillus gasseri (18), lactobacillus rhamnosus (14), lactobacillus paracasei (12), lactobacillus mucosae (12), lactobacillus oris (12), lactobacillus plantarum (11) and lactobacillus vaginalis (10) were used as producer strain ... | 2011 | 21801186 |
| acid production and growth by oral lactobacillus species in vitro. | to analyze the acid-producing and growth abilities of different oral lactobacillus species. | 2011 | 22298522 |
| characterization of some bacteriocins produced by lactic acid bacteria isolated from fermented foods. | lactic acid bacteria (lab) isolated from different sources (dairy products, fruits, fresh and fermented vegetables, fermented cereals) were screened for antimicrobial activity against other bacteria, including potential pathogens and food spoiling bacteria. six strains have been shown to produce bacteriocins: lactococcus lactis 19.3, lactobacillus plantarum 26.1, enterococcus durans 41.2, isolated from dairy products and lactobacillus amylolyticus p40 and p50, and lactobacillus oris p49, isolate ... | 2014 | 24849010 |
| complete genome sequence of lactobacillus oris j-1, a potential probiotic isolated from the human oral microbiome. | lactobacilli can exert health-promoting effects in the human oral microbiome through many mechanisms, including pathogen inhibition, maintenance of microbial balance, immunomodulation, and enhancement of the epithelial barrier function. here, we present the complete genome sequence of a potential probiotic, lactobacillus oris j-1, that was isolated from the oral cavity of a health child. | 2016 | 27634996 |
| control of lupus nephritis by changes of gut microbiota. | systemic lupus erythematosus, characterized by persistent inflammation, is a complex autoimmune disorder with no known cure. immunosuppressants used in treatment put patients at a higher risk of infections. new knowledge of disease modulators, such as symbiotic bacteria, can enable fine-tuning of parts of the immune system, rather than suppressing it altogether. | 2017 | 28697806 |
| multiplex pcr for the detection of lactobacillus pontis and two related species in a sourdough fermentation. | a specific multiplex pcr assay based on the amplification of parts of the 16s rrna molecule was designed. primers derived from variable regions of the 16s rrna provided a means of easily differentiating the species lactobacillus pontis and lactobacillus panis. they could be clearly discriminated from the phylogenetically related species lactobacillus vaginalis, lactobacillus oris, and lactobacillus reuteri and from other lactobacilli commonly known to be present in sourdough. other strains isola ... | 2000 | 10788389 |
| isolation and characterization of the microflora of nixtamalized corn masa. | corn tortillas are a staple in the diet among the mexican population, and are traditionally produced through a process known as nixtamalization. this traditional process involves steeping whole-kernel corn in an alkaline solution overnight and then grinding the corn into dough (masa), which is then baked. while the masa is held before baking, significant microbial change can occur which leads to fermentation and spoilage. the objective of this research was to characterize and identify the microf ... | 2013 | 23803568 |
| isolation of potential probiotic lactobacillus oris hmi68 from mother's milk with cholesterol-reducing property. | the objective of this study was to evaluate the probiotic properties of lactobacillus strains isolated from mother's milk and their effects on cholesterol assimilation. in this study 120 isolates from mother's milk were phenotypically and genotypically characterized. among these, only 6 predominant strains were identified as lactobacillus spp. the following parameters were selected as important test variables in model stomach passage survival trials: acid and bile tolerance, antimicrobial activi ... | 2014 | 24613732 |
