Populations of a single bacterial species can possess a great diversity of type VI secretion systems (T6SSs) and secreted effectors. Here, Habich et al. apply molecular population genetics to the T6SSs of Pseudomonas aeruginosa, highlighting the potential importance of T6SS intraspecific diversity in bacterial ecology and evolution.
