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 ...

Infection Kinetics and Phylogenetic Analysis of vB_EcoD_SU57, a Virulent T1-Like Drexlerviridae Coliphage

Frontiers in Microbiology, 2020
The morphology, infection kinetics, genome sequence and phylogenetic characterization of the previously isolated bacteriophage vB_EcoD_SU57 are presented. The phage vB_EcoD_SU57 was isolated on Escherichia coli strain ECOR57 from the E.

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

Isolation and characterization of coliphages from different water sources and their biocontrol application combined with electron beam irradiation for elimination of E. coli in domestic wastewater

Annals of Microbiology
Background Antibiotic-resistant bacteria, including Escherichia coli (E. coli), are high-risk waterborne pathogens that pose a vital threat to the general public’s health.

In situ structures of the genome and genome-delivery apparatus in a single-stranded RNA virus. [PDF]

, 2016
Packaging of the genome into a protein capsid and its subsequent delivery into a host cell are two fundamental processes in the life cycle of a virus. Unlike double-stranded DNA viruses, which pump their genome into a preformed capsid, single-stranded ...

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.

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.

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

Applied 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

Endemic bacteriophages: a cautionary tale for evaluation of bacteriophage therapy and other interventions for infection control in animals

Virology Journal, 2012
Background One of the most effective targets for control of zoonotic foodborne pathogens in the farm to fork continuum is their elimination in food animals destined for market.

TIGHT REPRESSION OF ELASTASE STRAIN K OVEREXPRESSION BY PT7 (A1/O4/O3) SHUTTLE EXPRESSION SYSTEM [PDF]

Science Heritage Journal, 2017
The PT7(A1/O4/O3) is a promoter resulted from construction of O3 and O4 operators into PA1, a promoter derived from coliphage T7, that evidenced lower the occupancy of the promoter by RNA polymerase and thereby increases the repression factor.
