Marine viruses have important roles in modulating the dynamics of microbial life in the global oceans. Brum and Sullivan discuss the recent technological advances that are facilitating an accelerated pace of discovery in marine virology, including metagenomics and several cultivation-dependent and cultivation-independent tools.
The base excision repair (BER) pathway is the most important mechanism for the repair of oxidative DNA damage, which is frequently encountered by host-adapted bacterial pathogens. Here, van der Veen and Tang review DNA repair in the human pathogensMycobacterium tuberculosis, Helicobacter pylori and Neisseria meningitidis, highlighting common and distinct mechanisms.
