Comparative proteomics of saliva of healthy and gingivitis individuals from Rio de Janeiro.

Purpose: In this work, we identified human and bacterial proteomes in the saliva from volunteers with gingivitis or healthy.

Experimental Design: The reported population consisted of 18 volunteers (six with gingivitis and 12 healthy controls). Proteomics characterization was performed using a quantitative mass spectrometry method.

Bacterial communities in the rhizosphere of biofortified BRS pontal and conventional carioca bean (Phaseolus vulgaris) plants.

The current knowledge of bean plants microbiome is far from being complete. Unraveling the complexity of the bacterial communities within common bean cultivars that may significantly contribute to plant health, growth and protection against soil pathogens, represents a major challenge. In this study, the richness and composition of the bacterial communities from bean plant rhizospheres and control bulk soils were analyzed by high-throughput sequencing and comparative analyses.
