Salmonella enterica serovar Enteritidis is a Gram-negative bacterium and one of the most common foodborne pathogens. Biocontrol using bacteriophage in food products or animals is one possible means by which pathogenic salmonellosis infection could be inhibited.

Phage Sepoy infects Salmonella enterica serovar Heidelberg, a Gram-negative bacterium that causes severe foodborne illnesses. Bacteriophages infecting this pathogen may be used as biocontrol agents for preventing Salmonella foodborne diseases. Here, we present the complete genome sequence of Sepoy, a T5-like siphophage.

ABSTRACT The VanX protein is a d-alanyl-d-alanine (d-Ala-d-Ala) dipeptidase essential for resistance to the glycopeptide antibiotic vancomycin. While this enzymatic activity has been typically associated with vancomycin- and teicoplainin-resistant enterococci, we now report the identification of a d-Ala-d-Ala dipeptidase in the gram-negative species Salmonella enterica. TheSalmonella enzyme is only 36% identical to VanX but exhibits a similar substrate specificity: it hydrolyzesd-Ala-d-Ala,dl-Ala-dl-Phe, and d-Ala-Gly but not the tripeptidesd-Ala-d-Ala-d-Ala anddl-Ala-dl-Lys-Gly or the dipeptidesl-Ala-l-Ala,N-acetyl-d-Ala-d-Ala, andl-Leu-Pro. The Salmonella dipeptidase gene, designated pcgL, appears to have been acquired by horizontal gene transfer because pcgL-hybridizing sequences were not detected in related bacterial species and the G+C content of the pcgL-containing region (41%) is much lower than the overall G+C content of the Salmonella chromosome (52%). In contrast to wild-type Salmonella, a pcgL mutant was unable to use d-Ala-d-Ala as a sole carbon source. The pcgL gene conferredd-Ala-d-Ala dipeptidase activity uponEscherichia coli K-12 but did not allow growth ond-Ala-d-Ala. The PcgL protein localizes to the periplasmic space of Salmonella, suggesting that this dipeptidase participates in peptidoglycan metabolism.

ABSTRACT Salmonella enterica is a Gram-negative bacterium, recognized as one of the most important foodborne pathogens in the world. Bacteriophages represent a promising alternative to the biocontrol of Salmonella. Here, we report the isolation of five Salmonella bacteriophages, the sequencing of their full genomes, and initial genomic characterization.
