Complete genome sequence of new bacteriophage phiE142, which causes simultaneously lysis of multidrug-resistant Escherichia coli O157:H7 and Salmonella enterica

Abstract

The emergence of antibiotic-resistant foodborne bacteria is a global health problem that requires immediate attention. Bacteriophages are a promising biotechnological alternative approach against bacterial pathogens. However, a detailed analysis of phage genomes is essential to assess the safety of the phages prior to their use as biocontrol agents. Therefore, here we report the complete genome sequence of bacteriophage phiE142, which is able to lyse <i>Salmonella</i> and multidrug-resistant <i>Escherichia coli</i> O157:H7 strains. Bacteriophage phiE142 belongs to the <i>Myoviridae</i> family due to the presence of long non-flexible tail and icosahedral head. The genome is composed of 121,442 bp and contains 194 ORFs, and 2 tRNAs. Furthermore, the phiE142 genome does not contain any genes coding for food-borne allergens, antibiotics resistance, virulence factors, or associated with lysogenic conversion. The bacteriophage phiE142 is characterized by broad host range and compelling genetic attributes making them potential candidates as a biocontrol agent.
