Molecular and biochemical analysis of the system regulating the lytic/lysogenic cycle in the pneumococcal temperate phage MM1 [PDF]
FEMS Microbiology Letters, 2003 The temperate phage MM1 forms stable lysogens in Streptococcus pneumoniae. We report here the first characterization of the lysogenic control region in Pneumococcus which contains two functional divergent promoters (P(R) and P(L)). MM1 encodes a 14-kDa cI protein (CI) that appears to be responsible for maintaining the lysogenic state in Pneumococcus ...

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.

Virology, 1999 Lysogenic induction of temperate bacteriophage A2 of Lactobacillus casei is controlled by the action of its cI and cro products at the phage operator region. Three 20-bp inverted repeated DNA segments (subsites O1, O2, and O3) and the two divergent (PL and PR) promoters were mapped within the 153-bp operator region.

Virus Research, 2014 Expression of bacteriophage A2-encoded cro in Escherichia coli gives rise to two co-linear polypeptides, Cro and Cro*, which were proposed to form a regulatory tandem to modulate the frequency with which the phage would choose between the lytic and the lysogenic cycles. In this communication, it is reported that Cro is the canonical product of the gene

Modulation of Lactobacillus casei bacteriophage A2 lytic/lysogenic cycles by binding of Gp25 to the early lytic mRNA [PDF]
Molecular Microbiology, 2015 SummaryThe genetic switch of Lactobacillus casei bacteriophage A2 is regulated by the CI protein, which represses the early lytic promoter PR and Cro that abolishes expression from the lysogenic promoter PL. Lysogens contain equivalent cI and cro‐gp25 mRNA concentrations, i.e., CI only partially represses PR, predicting a lytic cycle dominance. However,

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.

Exploring the Lytic and Lysogenic Life Cycles of Bacteriophages
CourseSource, 2021 The goal of this lesson is to introduce students to the lytic and lysogenic cycles of T4 and lambda bacteriophages, respectively, using student-centered pedagogies.

Environmental Microbiology, 2013 Summary Changes in environmental conditions and prokaryote physiology can strongly affect the dynamics of both the lysogenic and lytic bacteriophage replication cycles in aquatic systems. However, it remains unclear whether it is the nature, amplitude or frequency of these changes that alter the phage replication ...

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.
