Members of the cosmopolitan Alteromonas are particularly synergistic, and chemotaxis towards infected algal cells seems to help them overcome their low abundance within the bloom microbiome.

Over time we learned more (and more to come) about how chemotaxis drives bacteria forward, and how by killing bacteria in the center, the phage leave a zone of relatively high nutrients & chemoattractants.
Bacteria migrate to this zone, and yet, it is a (moving) trap.
