Two cases of type 2 diabetes mellitus successfully treated with probiotics.

The gut microbiota, and particularly probiotic bacteria, has emerged as a promising and novel intervention to fight the looming worldwide diabetes epidemic when combined with the appropriate medication. Herein, we report two cases of patient with type 2 diabetes refractory to conventional therapy that showed notable improvement after probiotic intervention.

Determination of NO and CSF Levels Produced by .

The cell-to-cell communication and division of labour that occurs inside a beneficial biofilm produce significant differences in gene expression compared with the gene expression pattern of cells grew under planktonic conditions. In this sense, the levels of NO (nitric oxide) and CSF (Competence Sporulation Stimulating Factor) produced in cultures have been measured only under planktonic growth conditions. We sought to determine whether NO and/or CSF production is affected in cells that develop as a biofilm.

Culturing Bacteria from Gut to Assess Colonization Proficiency.

Determining an accurate count of intestinal bacteria from is one critical way to assess colonization proficiency by a given bacteria. This can be accomplished by culturing appropriate dilutions of worm gut bacteria on selective or differential agarized media. Because of the high concentration of bacteria in gut worm, dilution is necessary before plating onto growth media.

Microbial flora, probiotics, and the search for a long and healthy human longevity.

Probiotics are live microorganisms that have beneficial effects on host health, including extended lifespan, when they are administered or present in adequate quantities. However, the mechanisms by which probiotics stimulate host longevity remain unclear and very poorly understood. In a recent study ( 8, 14332 (2017) doi: 10.

Transcriptional regulation of adhesive properties of Bacillus subtilis to extracellular matrix proteins through the fibronectin-binding protein YloA.

Bacterial adherence to extracellular matrix proteins (ECMp) plays important roles during host-pathogen interaction, however its genetic regulation remains poorly understood. yloA of the model bacterium Bacillus subtilis shows high homology to genes encoding fibronectin-binding proteins of Gram-positive pathogens. Here, we characterized the regulatory network of YloA-dependent adhesive properties of the probiotic B.

Bacillus subtilis biofilm extends Caenorhabditis elegans longevity through downregulation of the insulin-like signalling pathway.

Beneficial bacteria have been shown to affect host longevity, but the molecular mechanisms mediating such effects remain largely unclear. Here we show that formation of Bacillus subtilis biofilms increases Caenorhabditis elegans lifespan. Biofilm-proficient B.
