Daily follow-up of bacterial communities in the human gut reveals stable composition and host-specific patterns of interaction

In the last decade, an extensive effort has been made to characterize the human intestinal microbiota by means of SSU rRNA gene sequence and metagenomic analysis. Relatively few studies have followed intestinal bacterial communities over time to assess their stability in the absence of perturbation. In this study authors have monitored the faecal bacteria of three healthy subjects during fifteen consecutive days.

Increased honey bee diversity means fewer pathogens, more helpful bacteria, IU biologist finds

Another first, research also finds probiotic species used by humans flourishing in colonies.

A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species.
