Biochemical Studies of EA22, A Protein Involved in The Bacteriophage Lysogenic-Lytic Decision and the Virulence of Clinically Relevant Serotypes of E. Coli
… that persists in the bacterium as a lysogen until it is activated by a stress-related event. While the lysogenic-lytic development decision has been characterized for decades, there are still genes that are unknown in every way, from structure to function. These genes are found in a …

The Genomic Sequence and Annotation of Bacteriophage HK239
… are released into the environment. In the lysogenic lifestyle, a phage integrates its genome into the host chromosome, creating a prophage. The cell containing the prophage is known as a lysogen. Most prophage genes are not expressed. However, those that are encode a wide variety of …

In Vivo Regulation Of Transcription Of The Escherichia Coli Rna Polymerase Genes Rpo(b) And Rpo(c)
… by measuring the b-galactosidase level in a lysogen carrying a transcriptional fusion phage. Two strong promoters, rplKp and rplJp, were identified along with a weak promoter, rplLp. A transcriptional attenuator, atn, located between rplL and rpoB, terminated 60 percent of transcription …

Characterization of the repressor from the lambdoid phage HK022.
… coliphage HK022 can grow in either a lytic or lysogenic mode following infection. In λ phage the switch to either mode is controlled by the cI and Cro repressors which bind to operators in the λ chromosome and regulate gene expression of adjacent promoters. HK022 is organized similar to λ, but …

Genetic mechanisms contributing to antimicrobial resistance: gene repression in Mycobacterium, gene transfer in Salmonella, and phage sensitivity in Escherichia
… was observed in EHEC strains with the stx2a lysogen. RT-qPCR and plasmid complementation experiments showed that the hypothetical gene H2 was not responsible for TP13 resistance. Subsequent review of recent literature revealed that the downstream tyrosine kinase stk is likely responsible for …

Isolation of bacteriophages against Streptococcus species; Lysogeny of Ten Mycobacteriophages for host Mycobacterium tuberculosis H37Ra
… from the human oral cavity. The second is lysogeny of mycobacteriophages originally obtained from Mycobacterium smegmatis mc2155 as a host that displayed successful cross-infection with Mycobacteria tuberculosis H37Ra in previous assays. Using the previous research, the bacteriophages …

Evolution of transmission mode in a temperate virus of Pseudomonas aeruginosa and its effects on the host

Collective dynamics of evolving populations and their strategies with application to medicine
… 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. In the presence of lysogeny, we analyze the possible states of the system, identifying a novel limit cycle, which we …

Untersuchungen zur Regulation von Shiga-Toxin 2 und zur Attenuierung von enterohämorrhagischen Escherichia coli
Enterohämorrhagische Escherichia coli (EHEC) gehören zu den wichtigsten der sich in jüngster Zeit verbreitenden Pathogene und verursachen die verschiedensten Durchfallerkrankungen von unblutiger Diarrhö bis zu hämorrhagischer Kolitis, oftmals unter Ausprägung von lebensbedrohlichen …
