Background Recent evidence suggests that there is a link between metabolic diseases and bacterial populations in the gut. The aim of this study was to assess differences composition intestinal microbiota humans with type 2 diabetes non-diabetic persons as control. Methods Findings included 36 male adults broad range age body-mass indices (BMIs), among which 18 subjects were diagnosed 2. fecal investigated by real-time quantitative PCR (qPCR) subgroup (N = 20) tag-encoded amplicon...
The probiotic potential of 47 selected strains Lactobacillus spp. was investigated. were examined for resistance to pH 2.5 and 0.3% oxgall, adhesion Caco-2 cells, antimicrobial activities against enteric pathogenic bacteria in model systems. From the results obtained vitro, five strains, rhamnosus 19070-2, L. reuteri DSM 12246, LGG, delbrueckii subsp. lactis CHCC 2329, casei alactus 3137, vivo studies. daily consumption by 12 healthy volunteers two doses 10(10) freeze-dried 18 days followed...
According to animal studies, intake of probiotic bacteria may improve glucose homeostasis. We hypothesised that insulin sensitivity by attenuating systemic inflammation. Therefore, the effects oral supplementation with bacterium Lactobacillus acidophilus NCFM on and inflammatory response were investigated in subjects normal or impaired sensitivity. In a double-blinded, randomised fashion, forty-five males type 2 diabetes, tolerance enrolled allocated 4-week treatment course either L....
Magnetic nanoparticles (MNP) can be used as contrast-enhancing agents to visualize tumors by magnetic resonance imaging (MRI). Here we describe an easy synthesis method of coated with polyethylene glycol (PEG) and demonstrate size-dependent accumulation in murine following intravenous injection. Biocompatible iron oxide MNPs PEG were prepared replacing oleic acid a biocompatible commercially available silane-PEG provide effective for chemical coating. The colloidal stable PEGylated...
Samples of cocoa beans were taken on two separate occasions during heap and tray fermentations in Ghana, West Africa. In total 496 yeast isolates identified by conventional microbiological analyses amplification their ITS1-5.8S rDNA-ITS2 regions. For important species the identifications confirmed sequencing D1/D2 domain 5' end large subunit (26S) rDNA. Assimilations organic acids other carbon compounds conducted. dominant yeasts intraspecies variations examined determination chromosome...
Background. Oral bacteriotherapy promotes recovery from acute childhood diarrhea, but few strains have been shown to therapeutic potentials. We examined the effect of two newly identified probiotic Lactobacillus in diarrhea. Methods. Sixty-nine children were randomized during hospitalization for diarrhea receive a mixture rhamnosus 19070-2 and reuteri DSM 12246, 1010 colony-forming units each strain or placebo twice daily 5 days. Before selection these stains their potential characteristics...
Aims: To identify and examine the diversity of predominant lactic acid bacteria (LAB) in koko sour water (KSW) from different Ghanaian production sites with regard to pattern fermentation (API 50 CHL), genotype, antimicrobial activity, resistance low pH bile salts. Methods Results: In total 215 LAB were isolated KSW. The isolates identified using intergenic transcribed spacers (ITS)‐PCR restriction fragment length polymorphism (RFLP), API CHL, enzyme analysis pulsed‐field gel electrophoresis...
The connections between gut microbiota, energy homeostasis, and inflammation its role in the pathogenesis of obesity-related disorders are increasingly recognized. We aimed to investigate effect probiotic strain Lactobacillus salivarius Ls-33 on a series biomarkers related metabolic syndrome (MS) adolescents with obesity.The study was double-blind placebo-controlled trial including 50 obesity randomized (10 CFU) or placebo daily for 12 weeks.The average body mass index-for-age z-score 2.6 ±...
ABSTRACT We describe the dynamics of changes in intracellular pH (pH i ) values a number lactic acid bacteria response to rapid drop extracellular ex ). Strains Lactobacillus delbrueckii subsp. bulgaricus , Streptococcus thermophilus and Lactococcus lactis were investigated. Listeria innocua gram-positive, non-lactic bacterium, was included for comparison. The method which we used based on fluorescence ratio imaging single cells, it therefore possible variations within population....
Background. Certain strains of lactobacilli have been shown to promote recovery from rotavirus enteritis in hospitalized children. Few studies examined the effect probiotics nonhospitalized children with mild diarrhea. Methods. We studied a randomized placebo-controlled trial lyophilized Lactobacillus rhamnosus 19070-2 and reuteri DSM 12246, 1010 colony-forming units each strain twice daily for 5 days, on acute diarrhea cohort recruited local day-care centers. The duration assessment stool...
Abstract Samples of Coffea arabica were collected during the different stages fermentation from two production sites in Tanzania. The yeasts community was identified by genotyping using ITS–PCR and sequence analysis D1/D2 domain 26S rRNA gene. For confirmation, denaturating gradient gel electrophoresis (DGGE) PCR‐amplified gene performed to detect yeast directly coffee samples without cultivation. Yeast counts range 4.0 × 10 4 − 5.0 7 CFU/g with an increase fermentation. Three species...
