The human body is home to a complex ecosystem of microbes increasingly recognised as having a critical role in both health and disease. Viruses can attack and change the composition of bacterial communities, yet little is known about how this might influence human health. In a study published online today in Genome Research (www.genome.org), scientists have performed the first metagenomic analysis of a bacterial immune system in humans over time, finding that the defences of the oral microbiome are unique and traceable, information that could help personalise oral health care in the future...
