Salmonella is a major causative agent of foodborne illness and rapid identification of this pathogen is essential to prevent disease. Currently most assays require high bacterial burdens or prolonged enrichment to achieve acceptable performance. A reduction in testing time without loss of sensitivity is critical to allow food processors to safely d...

It is difficult to precisely target bacterial populations in the mammalian gut. Here the authors use encapsulated phages to deliver dCas9 to E. coli in the mouse gut to modulate RFP expression.

Despite phages’ ubiquitous presence and great importance in shaping microbial communities, little is known about the diversity of specific phages in different ecological niches. Here, we isolated, sequenced, and characterized 38 Escherichia coli-infecting phages (coliphages) from poultry faeces to gain a better understanding of the coliphage divers...

Viruses have been difficult to position in the Tree of Life using phylogenetic methods. This study uses an ancient enzyme multi-subunit RNA polymerase (RNAP) to reveal a novel viral group, the Caudovirales, and to suggest an ancient origin of RNAP in this group.

Double-stranded DNA tailed bacteriophages typically code for 50–200 genes, of which 15–35 are involved in virion structure and assembly, DNA packaging, lysis, and DNA metabolism. However, vast numbers of other phage genes are small, are not required for lytic growth, and are of unknown function. The 1,885 sequenced mycobacteriophages encompass over...

We investigated the use of bacteriophages as a strategy to decolonize intestinal carriers of multidrug-resistant Escherichia coli. A fermentor was used as a continuous culture system for 48h. Two different pools of faeces (studies I and II) obtained from volunteers were spiked with a CTX-M-15-producing ST131 E. coli (strain 4901.28) susceptible to ...

The emergence of antibiotic resistance has raised serious concerns within scientific and medical communities, and has underlined the importance of developing new antimicrobial agents to combat such infections. Bacteriophages, naturally occurring bacterial viruses, have long been characterized as promising antibiotic alternatives. Although bacteriop...

Pseudomonas aeruginosa is an opportunistic pathogen that thrives in diverse environments and causes a variety of human infections. Pseudomonas aeruginosa AG1 (PaeAG1) is a high-risk sequence type 111 (ST-111) strain isolated from a Costa Rican hospital in 2010. PaeAG1 has both blaVIM-2 and blaIMP-18 genes encoding for metallo-β-lactamases, and it i...

Klebsiella species are able to colonize a wide range of environments and include worrisome nosocomial pathogens. Here, we sought to determine the abundance and infectivity of prophages of Klebsiella to understand how the interactions between induced prophages and bacteria affect population dynamics and evolution. We identified many prophages in the...
