Genome sequencing of a global collection of Shigella sonnei or baciliary dysentery, in developing countries is reported in a study published in Nature Genetics. Their study provides insights into the course of recent shigellosis epidemics. S. sonnei are human-adapted E. coli responsible for approximately 150 million cases of dysentery each year.

Two independent studies published in Nature this week identify specific subsets of cells in mouse tumours that seem to be responsible for the re-growth of tumours. These findings shed new light on the controversial issue of whether cancer stem cells exist in growing tumours and may have implications for potential therapies.
