Comprehensive analysis of predominant pathogenic bacteria and viruses in seafood products

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Given the growing global demand for seafood, it is imperative to conduct a comprehensive study on the prevalence and persistence patterns of pathogenic bacteria and viruses associated with specific seafood varieties. This assessment thoroughly examines the safety of seafood products, considering the diverse processing methods employed in the ...

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

Microbial 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

High-resolution cryo-EM structure of the Pseudomonas bacteriophage E217

Nature Communications, 2023
E217 is a Pseudomonas phage used in an experimental cocktail to eradicate cystic fibrosis-associated Pseudomonas aeruginosa. Here, we describe the structure of the whole E217 virion before and after DNA ejection at 3.1 Å and 4.5 Å resolution ...

Isolation and characterization of a phage collection against Pseudomonas putida

Environmental 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.

Control of gene expression in P2-related coliphages: the in vitro transcription pattern of coliphage 186. [PDF]

The EMBO Journal, 1985
Transcription in vitro of coliphage 186 DNA generated four transcripts. The most abundant transcript was that of the late control gene B and an equivalent transcript was identified for the closely related phage P2. A second transcript was from the rightward promoter at 75% and predicted to be under CI repressor control.

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

Molecular 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 ...

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

Microbial 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 ...
