The pool of microbes inhabiting our body is known as "microbiota" and their collective genomes as "microbiome". The colon is the most densely populated organ in the human body, although other parts, such as the skin, vaginal mucosa, or respiratory tract, also harbour specific microbiota. This microbial community regulates some important metabolic and(More)
Stomach mucosa biopsies and gastric juices samples of 12 healthy persons were analysed by culturing in selective- and non-selective-rich media. Microbial DNA from four mucosal samples was also amplified by nested PCR using universal bacterial primers, and the 16S rDNA amplicons pyrosequenced. The total number of cultivable microorganisms recovered from the(More)
Forty two Propionibacterium isolates were recovered from biopsy samples of the gastric mucosa of eight out of 12 healthy people. Of these, 41 were identified as belonging to Propionibacterium acnes; the remaining isolate was identified as belonging to Propionibacterium granulosum. Repetitive extragenic palindromic (REP)-PCR typing suggested that up to four(More)
Lactic acid bacteria (LAB) are responsible for different types of food fermentations that provide humans with many different classes of fermented products. During the 20th century, some LAB strains as well as several members of the genus Bifidobacterium started to be extensively used in human nutrition as probiotics because of their health-promoting(More)
BACKGROUND Recent years have seen increasing interest in the complex microbial ecosystem of the human gastrointestinal tract. Knowledge of its microbial colonists and their beneficial/detrimental activities is important. However, generalized assumptions about the microbial composition of the human gut should be taken with caution until more studies in(More)
Humoral response in cancer patients appears early in cancer progression and can be used for diagnosis, including early detection. By using human recombinant protein and T7 phage microarrays displaying colorectal cancer (CRC)-specific peptides, we previously selected 6 phages and 6 human recombinant proteins as tumor-associated antigens (TAAs) with high(More)
The characterization of the humoral response in cancer patients is becoming a practical alternative to improve early detection. We prepared phage microarrays containing colorectal cancer cDNA libraries to identify phage-expressed peptides recognized by tumor-specific autoantibodies from patient sera. From a total of 1536 printed phages, 128 gave(More)
The aim of this study was to identify numerically dominant cultivable lactobacilli species in the feces of healthy adults. Ten individuals from Asturias, northern Spain, were chosen. Bacterial colonies grown under anoxic conditions on MRS with cysteine were microscopically examined for lactobacilli. Isolates were subsequently grouped based on the analysis(More)
The aim of this work was to examine by culturing the changes in the total and indicator populations of the feces of two individuals over 1 year and to identify the dominant microbial components of a single sample of feces from each donor. Populations and dominant bacteria from a sample of colonic mucosa from a further individual were also assessed. The(More)
