Paucity of adaptive selection in PmrAB two-component system may resist emergence of colistin resistance in Acinetobacter baumannii

The paper analyzes adaptive selection in the PmrAB two-component system of Acinetobacter baumannii and finds no evidence of positive selection, suggesting colistin resistance may not emerge easily.

Evaluating bacterial and functional diversity of human gut microbiota by complementary metagenomics and metatranscriptomics

The paper evaluates bacterial diversity and functional gene expression in the human gut microbiota using metagenomics and metatranscriptomics, showing that 52% of metagenomic genes are expressed and some low-abundance species are metabolically active.
