Bacterial persistence poses a major obstacle for current efforts to tackle the global rise of antibiotic resistance. Here, Balaban, Gerdes, Lewis and McKinney discuss the physiological features of persister cells and the factors leading to their emergence, as well as the implications of persistence for antibiotic treatment regimens and bacterial heterogeneity.
Here, Blaser, Bork, Fraser, Knight and Wang highlight the most exciting findings in the field of microbiome research and discuss what will be necessary to obtain a better understanding of the role of the microbiota in human health and disease, and to develop microbiota-based therapies.
