Common occurrence of antibacterial agents in human intestinal microbiota.

Laboratory experiments have revealed many active mechanisms by which bacteria can inhibit the growth of other organisms. Bacteriocins are a diverse group of natural ribosomally synthesized antimicrobial peptides produced by a wide range of bacteria and which seem to play an important role in mediating competition within bacterial communities. In this study, we have identified and established the structural classification of putative bacteriocins encoded by 317 microbial genomes in the human intestine.

[Creation of a consumer representatives committee in a multidisciplinary primary health care center. Findings, limitations and prospects].

Introduction: The St Claude multidisciplinary health centre in Besançon encouraged the creation of a consumer representatives committee to promote health democracy in primary health care. This project was developed with the help of a local consumers association. This study evaluated the perception and expectations of these fifteen health users/citizens.

A DNA microarray for the versatile diagnosis of infectious diarrhea.

Several bacteria, viruses, and parasites cause diarrhea as coinfecting pathogens. We designed a DNA microarray comprising 60-bp probes spotted 194 times for the multiplex detection of 33 enteropathogenic bacteria and seven enteropathogenic viruses, and the archaeon Methanobrevibacter smithii was used as an internal positive control. Nine pathogen-free stool specimens were used as negative controls.

Anopheles salivary gland proteomes from major malaria vectors.

Background: Antibody responses against Anopheles salivary proteins can indicate individual exposure to bites of malaria vectors. The extent to which these salivary proteins are species-specific is not entirely resolved. Thus, a better knowledge of the diversity among salivary protein repertoires from various malaria vector species is necessary to select relevant genus-, subgenus- and/or species-specific salivary antigens.
