13. Efeito da utilização de culturas láticas probióticas na microbiota vaginal de pacientes acometidas por infecções bacterianas e fúngicas / Effect of lactic acid probiotic cultures utilization on the vaginal microbiota of women diagnosed with bacterial and fungal infections
A microbiota vaginal saudável é constituída, majoritariamente, por espécies de lactobacilos que representam uma barreira natural contra microrganismos causadores de doenças como a candidíase vulvovaginal (CVV), vaginose bacteriana (VB) e infecções do trato urinário (ITU), que juntas acometem cerca de um bilhão de mulheres no mundo anualmente. Um me

14. Identificação, caracterização e análise da expressão de genes de resposta ao estresse oxidativo em Lactobacillus delbrueckii UFV H2b20 / Identification, characterization and expression analysis of oxidative stress response genes in Lactobacillus delbrueckii UFV H2b20
Oxidative stress is an important cause of viability loss in lactic acid bacteria used in food industry and as probiotics. This work aimed at identifying and characterize genes involved in the oxidative stress response in Lactobacillus delbrueckii UFV H2b20, a potencial probiotic strain. Therefore, dps, which encodes a ferritin-like protein, and pox, which en

15. Molecular phylogeny and comparative genomics of Gram- positive bacteria of the gastrointestinal tract / Filogenia molecular e genômica comparativa de bactérias Grampositivas do trato gastrointestinal
Recent information on the complete genome of probiotic lactic acid bacteria and Listeria monocytogenes, and the elucidation on those caused on large clusters of virulence genes, denominated pathogenicity islands (PAIs) present in L. monocytogenes, have brought the attention to the likely existence of gene sequences common to both groups, probiotic and entero

16. Identificação de Lactobacillus spp. de cama de frango no Brasil
Foram identificadas cepas de Lactobacillus spp. de 100 amostras de camas de frango coletadas de diferentes regiões de produção avícola do Brasil. Foram isoladas dez espécies diferentes de Lactobacillus: L. plantarum, L. casei subsp. pseudoplantarum, L. delbrueckii subsp. delbrueckii, L. reuteri, L. murinus, L. agilis, L.delbrueckii subsp. lactis, L. sal

17. Determinação da microbiota bacteriana de mosto e de dornas na fermentação alcoolica
Samples of concentrated yeast cell suspension diluted before the addition of sulfuric acid, of the same concentrated yeast cell suspension after addition and action of sulfuric acid, of must added to the same concentrated yeast cell suspension collected and of fermented must from the same fermentation tank, were collected between July and December of 1986, a

18. Influencia do resfriamento em torre sobre a microbiota do caldo de cana no processo de produção de alcool
Amostras de caldo de cana clarificado, pasteurizado e pré-resfriado foram coletadas na entrada e saída de uma torre de resfriamento (Modelo PV/INS 155 - Alpina S/A Ind.e Comércio) da Usina MODELO de Piracicaba - SP, no final da safra de cana de 1985. Contagens de aeróbios em placas evidenciaram uma significativa variação no número de contaminantes do

19. Colonization and Immunomodulation by Lactobacillus reuteri ATCC 55730 in the Human Gastrointestinal Tract
Lactobacillus reuteri ATCC 55730 is a probiotic (health-promoting) bacterium widely used as a dietary supplement. This study was designed to examine local colonization of the human gastrointestinal mucosa after dietary supplementation with L. reuteri ATCC 55730 and to determine subsequent immune responses at the colonized sites. In this open clinical investi

20. Live Lactobacillus reuteri Is Essential for the Inhibitory Effect on Tumor Necrosis Factor Alpha-Induced Interleukin-8 Expression
The mechanism of the apparent anti-inflammatory action of probiotic organisms is unclear. Lactobacillus reuteri is effective in inhibiting colitis in interleukin-10 (IL-10)-deficient mice. Nerve growth factor (NGF), in addition to its activity on neuronal cell growth, has significant anti-inflammatory effects in several experimental systems in vitro and in v

21. Conjugal transfer of plasmid pAM beta 1 in Lactobacillus reuteri and between lactobacilli and Enterococcus faecalis.
The broad-host-range plasmid pAM beta 1 (erythromycin resistance) was transferred conjugally from Streptococcus lactis to Lactobacillus reuteri, L. murinus, and L. fermentum. Transfer of pAM beta 1 between two L. reuteri strains occurred, and lactobacillus transconjugants could act as donors of pAM beta 1 in crosses with Enterococcus faecalis JH2-2.

22. Lactobacillus reuteri CRL1098 Produces Cobalamin
We found that Lactobacillus reuteri CRL1098, a lactic acid bacterium isolated from sourdough, is able to produce cobalamin. The sugar-glycerol cofermentation in vitamin B12-free medium showed that this strain was able to reduce glycerol through a well-known cobalamin-dependent reaction with the formation of 1,3-propanediol as a final product. The cell extrac

23. Molecular Characterization of a Novel Glucosyltransferase from Lactobacillus reuteri Strain 121 Synthesizing a Unique, Highly Branched Glucan with α-(1→4) and α-(1→6) Glucosidic Bonds
Lactobacillus reuteri strain 121 produces a unique, highly branched, soluble glucan in which the majority of the linkages are of the α-(1→4) glucosidic type. The glucan also contains α-(1→6)-linked glucosyl units and 4,6-disubstituted α-glucosyl units at the branching points. Using degenerate primers, based on the amino acid sequences of conserved reg

24. Denaturing Gradient Gel Electrophoresis Analysis of 16S Ribosomal DNA Amplicons To Monitor Changes in Fecal Bacterial Populations of Weaning Pigs after Introduction of Lactobacillus reuteri Strain MM53
The diversity and stability of the fecal bacterial microbiota in weaning pigs was studied after introduction of an exogenous Lactobacillus reuteri strain, MM53, using a combination of cultivation and techniques based on genes encoding 16S rRNA (16S rDNA). Piglets (n = 9) were assigned to three treatment groups (control, daily dosed, and 4th-day dosed), and f
