Fixed points and limit cycles in the population dynamics of lysogenic viruses and their hosts [PDF]
Physical Review E, 2010 Starting with stochastic rate equations for the fundamental interactions between microbes and their viruses, we derive a mean field theory for the population dynamics of microbe-virus systems, including the effects of lysogeny. In the absence of lysogeny, our model is a generalization of that proposed phenomenologically by Weitz and Dushoff.

Biofilm spatial structure and superinfection immunity modulate inter-phage competition. [PDF]
PLoS BiologyObligately lytic (virulent) phages always lyse host cells to release progeny viruses, while temperate phages can either lyse their hosts or integrate into host genomes as prophages, forming lysogens.

Precision targeting of genetic variations in mixed bacterial cultures using CRISPR-Cas12a-programmed λ phages [PDF]
Frontiers in MicrobiologyThe CRISPR-Cas system, an adaptive immune mechanism in prokaryotes against bacteriophages, has been developed into a versatile tool for recognizing and cleaving target nucleic acid sequences.

Characterization of Mu-Like Yersinia Phages Exhibiting Temperature Dependent Infection
Microbiology Spectrum, 2023 Yersinia pestis is the etiological agent of plague. Marmota himalayana of the Qinghai-Tibetan plateau is the primary host of flea-borne Y. pestis. This study is the report of isolation of Mu-like bacteriophages of Y. pestis from M. himalayana.

Inference of the Life Cycle of Environmental Phages from Genomic Signature Distances to Their Hosts
Viruses, 2023 The environmental impact of uncultured phages is shaped by their preferred life cycle (lytic or lysogenic). However, our ability to predict it is very limited.

Characterization of a New Temperate Escherichia coli Phage vB_EcoP_ZX5 and Its Regulatory Protein
Pathogens, 2022 The study of the interaction between temperate phages and bacteria is vital to understand their role in the development of human diseases. In this study, a novel temperate Escherichia coli phage, vB_EcoP_ZX5, with a genome size of 39,565 bp, was isolated

BACPHLIP: predicting bacteriophage lifestyle from conserved protein domains [PDF]
PeerJ, 2021 Bacteriophages are broadly classified into two distinct lifestyles: temperate and virulent. Temperate phages are capable of a latent phase of infection within a host cell (lysogenic cycle), whereas virulent phages directly replicate and lyse host cells ...

Low Host Abundance and High Temperature Determine Switching from Lytic to Lysogenic Cycles in Planktonic Microbial Communities in a Tropical Sea (Red Sea) [PDF]
Viruses, 2020 The lytic and lysogenic life cycles of marine phages are influenced by environmental conditions such as solar radiation, temperature, and host abundance. Temperature can regulate phage infection, but its role is difficult to discern in oligotrophic waters where there is typically low host abundance and high temperatures.

The Induction of the Lytic Cycle in Lysogenic Bacteria by Phagolessin A 58 [PDF]
Journal of General Microbiology, 1956 SUMMARY: Phagolessin A58, an antibiotic having antiphage activity, was found to have an action which induced the lytic cycle in some strains of lysogenic bacteria. Four different lysogenic organisms were tested: Bacillus megaterium 899; Escherichia coli FCb; E. coli Temple; E. coli Lampert.
