Diagram representing the impacts of viruses on aqueous sediment geochemistry. Organic matter (OM) sinks to the sediments, which is cycled in the microbial community, as well as increasing abundance, diversity, activity, and degradation of OM. From this “microbial loop” recalcitrant dissolved organic matter (RDOM) and dissolved inorganic carbon (DIC) are stored in sediments. Carbon is also released into the atmosphere from the sediment, and viral infection transfers genes between hosts or releases exogenous DNA to be used by bacteria, potentially aiding in metabolic activity. Created in BioRender. Williams, J. (2026) https://BioRender.com/b4wqimp.

Illustration of the relationship between two CRISPR arrays of C. sakazakii ST13 (A) and ST256 (B) strains. The leader proximal end of each array is on the left and the distal end is on the right. The black bar represents that this spacer is found only in one array. Two types of ancestral spacers in ST13 CRISPR1 arrays are marked with gray boxes. The spacers sak1-79 and sak1-750 targeting the sequences of phages are marked with blue and pink stars, respectively. CT types harboring mcr-9.1-positive strains are highlighted in red.
