“…Lysogeny is proposed as a survival strategy for phages in oligotrophic environments ( Stewart & Levin, 1984 ), but also occurs frequently at high host densities ( Silveira, Luque & Rohwer, 2021 ). Our results show, that the lytic infection and the temperate infection PtW enabled bacterial coexistence and stable infection dynamics at low nutrient concentrations.…”

“…In our model the lysogenic infected bacteria can outcompete non-infected bacteria because of the high phage number infecting bacteria at high resource levels. In natural systems the number of phage coinfections increases at high microbial abundances, which favors phage integration and thus lysogenic infections ( Luque & Silveira, 2020 ; Silveira, Luque & Rohwer, 2021 ). A phage integration into bacterial genome at high host densities can have advantages for bacteria.…”

“…The internal volumes of these capsids accommodate genomes spanning three orders of magnitude in length, from 5 kilobase pairs (kbp) to 735 kbp [82] , [62] . The diversity in genome length and genomic content of tailed phages may explain their key role in regulating ecosystems [86] , [113] , in promoting the evolution of microbes [129] , [67] , [121] , in participating strongly in the planetary carbon cycle [74] , and in becoming the most abundant biological entity on the planet [27] . However, the role of the diversity in tailed phage capsid architectures and genome lengths across ecosystems remains unclear.…”

“…Co-adaptation has also been observed with CrAss-like-phages (e.g., FCrAss001) that co-exist with their Bacteroides host and persist in high abundance in the human gut [15] through a lytic-lysogeny intermediate [14, 16]. Dense populations of replicating bacteria [17, 18], as found in the gut, show increased rates of lysogeny through ‘piggyback-the-winner’ dynamics [19, 20]. Increased bacterial density increases the rate of lysogeny by phage coinfection [20], or through host-density regulated molecular switches [21].…”

“…Once integrated, prophages can provide a fitness advantage to their bacterial host through protection from further infection by superinfection exclusion or immunity [22], and the introduction of new genes encoding for virulence factors, antibiotic resistance, or novel metabolic functions [23]. In this case, prophages persist by 'making-the-winner' [20].…”
