Characterization of a novel Phietavirus genus bacteriophage and its potential for efficient transfer of modified shuttle plasmids to Staphylococcus aureus strains of different clonal complexes

Microbiology Spectrum
Staphylococcus aureus is a significant human pathogen responsible for various nosocomial and community-acquired infections, leading to considerable morbidity and mortality worldwide. Temperate bacteriophages contribute to its virulence and facilitate the

KPC-2-Producing Carbapenem-Resistant Klebsiella pneumoniae of the Uncommon ST29 Type Carrying OXA-926, a Novel Narrow-Spectrum OXA β-Lactamase

Frontiers in Microbiology, 2021
We isolated and characterized a carbapenem-resistant Klebsiella pneumoniae (CRKP) clinical strain from blood carrying a novel blaOXA gene, blaOXA–926, and belonging to ST29, an uncommon CRKP type. The strain, 130002, was genome sequenced using both short-

Genetic Insights on Meropenem Resistance Concerning Klebsiella pneumoniae Clinical Isolates

Life
The transferable genetic elements are associated with the dissemination of virulence determinants amongst Klebsiella pneumoniae. Thus, we assessed the correlated antimicrobial resistance in carbapenem-resistant Klebsiella pneumoniae clinical isolates ...

A Primary Physiological Role of Toxin/Antitoxin Systems Is Phage Inhibition

Frontiers in Microbiology, 2020
Toxin/antitoxin (TA) systems are present in most prokaryote genomes. Toxins are almost exclusively proteins that reduce metabolism (but do not cause cell death), and antitoxins are either RNA or proteins that counteract the toxin or the RNA that encodes ...

First Report of a Methicillin-Resistant, High-Level Mupirocin-Resistant Staphylococcus argenteus

Frontiers in Cellular and Infection Microbiology, 2022
We describe the identification of a methicillin-resistant, high-level mupirocin-resistant Staphylococcus argenteus. The isolate (1801221) was characterized as t6675-ST2250-SCCmecIVc, and whole-genome sequencing revealed that the isolate possessed two ...

Emergence of plasmid stability under non-selective conditions maintains antibiotic resistance

Nature Communications, 2019
Plasmid acquisition is an important mechanism of rapid adaptation and niche expansion in prokaryotes. Positive selection for plasmid-coded functions is a major driver of plasmid evolution, while plasmids that do not confer a selective advantage are ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Intramuscular DNA vaccine provides protection in non-human primate and mouse models of SARS-CoV-2

Frontiers in Immunology
Nucleic acid vaccine approaches have proven successful in the context of the SARS-CoV-2 pandemic, however challenges with delivery remain. Here we describe PlaCCine, a DNA-based vaccine platform that utilizes a device- and vector-free chemical delivery ...

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

FEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.
