Optimized replication of arrayed bacterial mutant libraries increase access to biological resources

The paper describes a protocol for replicating arrayed bacterial mutant libraries to improve their distribution and quality control.

The phosphatase Bph and peptidyl-prolyl isomerase PrsA are required for gelatinase expression and activity in Enterococcus faecalis

This study identifies Bph phosphatase and PrsA as regulators of gelatinase expression and activity in Enterococcus faecalis, expanding the known regulatory network for this virulence factor.

Comparative biofilm assays using Enterococcus faecalis OG1RF identify new determinants of biofilm formation

This study identifies new genetic determinants of biofilm formation in E. faecalis using TnSeq and validates them with multiple biofilm assays, showing medium- and time-dependent effects on biofilm architecture.

Phage infection and sub-lethal antibiotic exposure mediate Enterococcus faecalis type VII secretion system dependent inhibition of bystander bacteria

This study shows that phage infection and sub-lethal antibiotics trigger T7SS in Enterococcus faecalis, inhibiting bystander bacteria through cell contact.

Genome-wide mutagenesis identifies factors involved in Enterococcus faecalis vaginal adherence and persistence

This study identifies bacterial factors important for Enterococcus faecalis vaginal colonization and persistence using a transposon mutagenesis screen in a mouse model.

Enterococcal PrgA extends far outside the cell and provides surface exclusion to protect against unwanted conjugation

This paper reports the structure and function of Enterococcus faecalis PrgA, showing it extends outside the cell to provide surface exclusion and reduce plasmid uptake.

Parallel genomics uncover novel enterococcal-bacteriophage interactions

The paper uses genomic approaches to study how Enterococcus faecalis responds to phage infection, identifying transcriptional regulators and gene expression changes that influence bacterial fitness and community interactions.

Extracellular Electron Transfer Powers Enterococcus faecalis Biofilm Metabolism

This study identifies a novel iron-dependent extracellular electron transfer (EET) mechanism in Enterococcus faecalis biofilms that enhances growth and matrix properties.
