The Importance of the Expendable: Toxin–Antitoxin Genes in Plasmids and Chromosomes

open access: yesFrontiers in Microbiology, 2017
Toxin–antitoxin (TA) genes were first reported in plasmids and were considered expendable genetic cassettes involved in the stable maintenance of the plasmid replicon by interfering with growth and/or viability of bacteria in which the plasmid was lost ...

Toxin-Antitoxin Systems in Clinical Pathogens

open access: yesToxins, 2016
Toxin-antitoxin (TA) systems are prevalent in bacteria and archaea. Although not essential for normal cell growth, TA systems are implicated in multiple cellular functions associated with survival under stress conditions. Clinical strains of bacteria are

Genomic Surveillance of Ceftriaxone-Resistant Escherichia coli in Western New York Suggests the Extended-Spectrum β-Lactamase blaCTX-M-27 Is Emerging on Distinct Plasmids in ST38

open access: yesFrontiers in Microbiology, 2020
Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae pose significant treatment and infection prevention challenges. Escherichia coli sequence type (ST) 131 associated with the blaCTX-M-15 gene has been the dominant lineage of ESBL-producing

Yersinia pestis pathogenicity

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии, 2019
Yersinia pestis belongs to those pathogenic bacteria which produce lipopolysaccharide (LPS) having the function of a toxin. In order to make a toxic effect the polymer must be separated from the cell outer membrane and presented to the immunocompetent ...

The Hypercomplex Genome of an Insect Reproductive Parasite Highlights the Importance of Lateral Gene Transfer in Symbiont Biology

open access: yesmBio, 2020
Mobile elements—plasmids and phages—are important components of microbial function and evolution via traits that they encode and their capacity to shuttle genetic material between species. We here report the unusually rich array of mobile elements within
