Enterococcal Metabolite Cues Facilitate Interspecies Niche Modulation and Polymicrobial Infection.

Enterococcus faecalis is frequently associated with polymicrobial infections of the urinary tract, indwelling catheters, and surgical wound sites. E. faecalis co-exists with Escherichia coli and other pathogens in wound infections, but mechanisms that govern polymicrobial colonization and pathogenesis are poorly defined.

Bacteriophage-based rapid and sensitive detection of Escherichia coli O157:H7 isolates from ground beef.

We investigated the efficacy of bacteriophage-based detection technology to detect Escherichia coli O157:H7 from ground beef. The assay involved a short enrichment period of 8 h followed by capture of the pathogen on O157-specific immunomagnetic beads. The captured cells were treated with O157-specific lytic bacteriophage, CSLO157.
