Determinants of bacteriophage 933W repressor DNA binding specificity.

open access: yesPLoS ONE, 2012
We reported previously that 933W repressor apparently does not cooperatively bind to adjacent sites on DNA and that the relative affinities of 933W repressor for its operators differ significantly from that of any other lambdoid bacteriophage.

On the Occurrence and Multimerization of Two-Polypeptide Phage Endolysins Encoded in Single Genes

open access: yesMicrobiology Spectrum, 2022
Bacteriophages (phages) and other viruses are extremely efficient in packing their genetic information, with several described cases of overlapping genes encoded in different open reading frames (ORFs).

Bacteriophage Adsorption Rate and Optimal Lysis Time [PDF]

open access: yesGenetics, 2008
Abstract The first step of bacteriophage (phage) infection is the attachment of the phage virion onto a susceptible host cell. This adsorption process is usually described by mass-action kinetics, which implicitly assume an equal influence of host density and adsorption rate on the adsorption process.

Design and evaluation of bacteriophage production for potential commercial use [PDF]

open access: yes, 2011
The purpose of this research was to evaluate the production of bacteriophages in a commercial plant. Bacteriophage K, a broad host range bacteriophage which is active against a wide range of staphylococci including MRSA, was used as a typical ...

Evaluation of the Ratio of Spot Tests and Plaque-Forming Activity Tests of Bacteriophages of Prevalent Pathogens

open access: yesЭпидемиология и вакцинопрофилактика
Relevance. Obtaining clean lysis spots, with tolerable presence of individual colonies of secondary growth, in spot tests is a criterion for assessing the effectiveness of therapeutic bacteriophages.

The lysis of dead bacteria by bacteriophage.

open access: yesExperimental Biology and Medicine, 1926
There is no difference of opinion that only young and actively growing bacteria are subject to transmissible lysis. Old or dead bacteria do not undergo lysis and do not contribute to the increase in concentration of the active lytic substance, but rather, on the contrary, bring about a measurable reduction of it.Recently, Twort1 has stated (somewhat ...

Cell fate decisions emerge as phages cooperate or compete inside their host

open access: yesNature Communications, 2017
The bacteriophage lambda and its hostEscherichia coli provide a model system to study cell-fate decisions. Here, Trinh et al. develop a four-colour fluorescence system at the single-cell/single-virus/single-viral-DNA level and find phages cooperate ...

Bioinformatic characterization of endolysins and holin-like membrane proteins in the lysis cassette of phages that infect Gordonia rubripertincta.

open access: yesPLoS ONE, 2022
Holins are bacteriophage-encoded transmembrane proteins that function to control the timing of bacterial lysis event, assist with the destabilization of the membrane proton motive force and in some models, generate large "pores" in the cell membrane to ...

Propagating the missing bacteriophages: a large bacteriophage in a new class

open access: yesVirology Journal, 2007
The number of successful propagations/isolations of soil-borne bacteriophages is small in comparison to the number of bacteriophages observed by microscopy (great plaque count anomaly).
