Mimicking prophage induction in the body: induction in the lab with pH gradients [PDF]
PeerJ, 2020 The majority of bacteria within the human body are lysogens, often harboring multiple bacteriophage sequences (prophages) within their genomes. While several different types of environmental stresses can trigger or induce prophages to enter into the ...

A new topology of the HK97-like fold revealed in Bordetella bacteriophage by cryoEM at 3.5 A resolution. [PDF]
, 2013 Bacteriophage BPP-1 infects and kills Bordetella species that cause whooping cough. Its diversity-generating retroelement (DGR) provides a naturally occurring phage-display system, but engineering efforts are hampered without atomic structures.

Effect of bacteriophage lysin on lysogens [PDF]
Asian Pacific Journal of Tropical Biomedicine, 2011 To study the effect of phage lysin on the growth of lysogens.Sputum specimens processed by modified Petroff's method were respectively treated with phagebiotics in combination with lysin and lysin alone. The specimens were incubated at 37 °C for 4 days.

Isolation and Genome Characterization of the Virulent Staphylococcus aureus Bacteriophage SA97
Viruses, 2015 A novel bacteriophage that infects S. aureus, SA97, was isolated and characterized. The phage SA97 belongs to the Siphoviridae family, and the cell wall teichoic acid (WTA) was found to be a host receptor of the phage SA97.

Network Models of Phage-Bacteria Coevolution [PDF]
, 2006 Bacteria and their bacteriophages are the most abundant, widespread and diverse groups of biological entities on the planet. In an attempt to understand how the interactions between bacteria, virulent phages and temperate phages might affect the ...

Transcription Analysis of Streptococcus thermophilus Phages in the Lysogenic State [PDF]
, 2002 The transcription of prophage genes was studied in two lysogenic Streptococcus thermophilus cells by Northern blot and primer-extension experiments. In the lysogen containing the cos-site phage Sfi21 only two gene regions of the prophage were transcribed.

Lysogenic Conversion of Rhizobium trifolii [PDF]
Journal of General Microbiology, 1970 Surmmary Rhizobium trifolii strain SU 297, when lysogenized with phage 7 or its clear-plaque mutant 7cr, underwent lysogenic conversion that resulted in loss of ability to adsorb phages 7 and 7cr and the related phage 8. The same conversion was reflected in changes in the surface of the bacterium by which a somatic antigen, characteristic of the parent

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage
Viruses, 2013 In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of
