A novel bacteriophage, PA-1, was isolated using Pantoea ananatis, a bacterium that is responsible for rice leaf blight worldwide, as the host. PA-1 has a linear genome of 46,332 bp with a GC content of 50.55%. It contains 83 protein-encoding genes, and no tRNA-encoding genes were detected. The genome is densely organized, with an average CDS size of 516 bp, and 92.38% of the genome consists of protein-coding regions. Whole-genome sequencing and phylogenetic and morphological analysis showed that PA-1 is a novel phage that is phylogenetically distinct, suggesting that it may represent a new genus within the class Caudoviricetes.​.

Cell lysis is one of the most common biological processes in which viruses infect and destroy bacterial cells. It is accomplished by viruses stimulating cell hosts to produce holin proteins that assemble in cellular membranes and break them at specific times. One of the most surprising observations in cell lysis is that antiholin proteins that inhibit membrane permeabilization are also produced.

Historically, broad-spectrum antibiotics have represented a major component of the therapeutic armamentarium used to treat common oral diseases associated with a bacterial etiology. The fact that these diseases are due to the accumulation of multispecies biofilms composed of ever-increasing numbers of resistant organisms has dramatically affected the efficacy of many of these drugs. Furthermore, it is now appreciated that repeated use of broad-spectrum antibiotics also affects the composition of the host commensal microbiota, which can have both local and systemic implications.

The COVID-19 pandemic underscored bacterial resistance as a critical global health issue, exacerbated by the increased use of antibiotics during the crisis. Notwithstanding the pandemic's prevalence, initiatives to address bacterial medication resistance have been inadequate. Although an overall drop in worldwide antibiotic consumption, total usage remains substantial, requiring rigorous regulatory measures and preventive activities to mitigate the emergence of resistance.

Background: Bacteriophages are the most genetically diverse biological entities in nature. Our current understanding of phage biology primarily stems from studies on a limited number of model bacteriophages. Jumbo phages, characterized by their exceptionally large genomes, are less frequently isolated and studied.

The phosphorylation of nucleic acids mediated by 5'-polynucleotide kinase (PNK) exerts a crucial regulatory function in a wide range of significant cellular activities. Nevertheless, the current approaches for detecting PNK require expensive labeled probes and complex instrumentation, making it impossible to achieve real-time, on-site, and rapid analysis. Here, we take T4 PNK as a model and establish a novel colorimetric strategy for the detection of PNK activity and its inhibition by means of a coupled enzyme-assisted cyclic strand displacement amplification (SDA) and peptide nucleic acid (PNA)-gold nanoparticle (AuNP) based platform.
