Diversity and Local Coadaptation of Escherichia coli and Coliphages From Small Ruminants

open access: yesFrontiers in Microbiology, 2020
Bacteriophages are highly specific predators that drive bacterial diversity through coevolution while striking tradeoffs among preserving host populations for long-term exploitation and increasing their virulence, structural stability, or host range ...

A nuclease domain fused to the Snf2 helicase confers antiphage defence in coral‐associated Halomonas meridiana

open access: yesMicrobial Biotechnology, Volume 17, Issue 7, July 2024.
Snf2‐related helicases from corals‐associated Halomonas meridiana mediate phage defence. We have characterized a novel defence gene hmaA, which encode a nickase activity containing helicase for defence against Escherichia coli phage T4. The analysis of the hma region reveals an insertion hot spot for defence systems and predicts the presence of several

Prophage Induction of Noninducible Coliphage 186 [PDF]

open access: yesJournal of Virology, 1974
Coliphage 186 has been regarded as a member of the noninducible group of coliphages. Evidence that prophage 186 is induced by ultraviolet irradiation or by treatment with nalidixic acid or mitomycin C is now presented. The phage yields were similar to those from lysogens of the inducible phage lambda, and the induction required a

Isolation and characterization of a phage collection against Pseudomonas putida

open access: yesEnvironmental Microbiology, Volume 26, Issue 6, June 2024.
This study presents the first collection of bacteriophages isolated specifically to act against the common laboratory strain, Pseudomonas putida PaW85. The collection comprises 67 double‐stranded DNA phages, which are classified into 22 species and 9 genera.

Redefining the bacteriophage mv4 site‐specific recombination system and the sequence specificity of its attB and core‐attP sites

open access: yesMolecular Microbiology, Volume 121, Issue 6, Page 1200-1216, June 2024.
While hundreds of mobile genetic elements utilising tyrosine recombinases (YRs) for integration and excision from bacterial genomes have been identified in databases, less than a dozen have been described in detail. Using in vitro recombination of randomized DNA libraries and high‐throughput sequencing analyses, we have characterised the recombination ...

Development of Coliphage N4: Ultrastructural Studies [PDF]

open access: yesJournal of Virology, 1974
The basic properties of bacteriophage N4 development have been investigated in Escherichia coli Hfr 3300 under one-step growth and high cell density conditions. N4 r + -infected bacteria are lysis inhibited in mass culture, burst asynchronously starting 180 min postinfection, and ...

Engineering strategies and challenges of endolysin as an antibacterial agent against Gram‐negative bacteria

open access: yesMicrobial Biotechnology, Volume 17, Issue 4, April 2024.
Bacteriophage endolysins have limited use against Gram‐negative bacteria for the envelop. To enhance the extracellular activity of endolysin and facilitate its crossing through the outer membrane of Gram‐negative bacteria, researchers have adopted physical, chemical, and molecular strategies for endolysin modification, to promote the application of ...

Molecular Typing of Somatic Coliphage Groups and Their Occurrence and Survival in Sewage

open access: yesApplied Microbiology
A conventional, group-specific PCR method was developed to identify each of the four previously defined major taxa (Myoviridae, Siphoviridae, Podoviridae and Microviridae) of somatic coliphages and used to classify isolates from sewage. Somatic coliphage

Dominant Vibrio cholerae phage exhibits lysis inhibition sensitive to disruption by a defensive phage satellite

open access: yeseLife, 2020
Bacteria, bacteriophages that prey upon them, and mobile genetic elements (MGEs) compete in dynamic environments, evolving strategies to sense the milieu. The first discovered environmental sensing by phages, lysis inhibition, has only been characterized
