NUP210 and coinfection: While previous quantification of viral DNA based on DAPI staining (15) suggests that ΦKZ is able to replicate faster than ΦPA3, potentially giving ΦKZ a replicative advantage, mathematical modeling shows that gp210 helps the less competitive phage ΦPA3 during co-infections with ΦKZ (Figs. S8–S10).
