This study aimed to inhibit Escherichia coli (E. coli) O157:H7 artificially contaminated in fresh meat using bacteriophage. Among 14 bacteriophages, the highly lytic bacteriophage BPECO19 strain was selected to inhibit E. coli O157:H7 in artificially contaminated meat samples. Bacteriophage BPECO19 significantly reduced E. coli O157:H7 bacterial load in vitro in a multiplicity of infection (MOI...

Lactococcus lactis subsp. lactis biovar. diacetylactis DPC721 is a spontaneous bacteriophage insensitive mutant of strain DPC220, isolated after challenge with an industrial bacteriophage, phi D1. Plasmid analysis demonstrated that the bacteriophage insensitivity was associated with the absence of two native DPC220 plasmids (pAH82 and pAH33), and the presence of a novel plasmid (pAH90) in DPC72...

Since the discovery of bacteriophage in the early 1900s, there have been numerous attempts to exploit their innate ability to kill bacteria. The purpose of this report is to review current findings and new developments in phage therapy with an emphasis on bacterial diseases of marine organisms, humans, and plants. The body of evidence includes data from studies investigating bacteriophage in ma...

Pseudomonas ΦKZ-like bacteriophages encode a group of related tubulin/FtsZ-like proteins believed to be essential for the correct centring of replicated bacteriophage virions within the bacterial host. In this study, we present crystal structures of the tubulin/FtsZ-like protein TubZ from Pseudomonas bacteriophage ΦKZ in both the monomeric and protofilament states, revealing that ΦKZ TubZ under...

Abstract Multiclass classification is a fundamental and challenging task in machine learning. The existing techniques of multiclass can be categorized as (1) decomposition into binary (2) extension from (3) hierarchical classification. Decomposing set classifications that efficiently solved by using classifiers, called class binarization, which popular technique for Neuroevolution, general powe...

The inactivation of staphylococcus bacteriophage by an artificially produced anti-phagic serum was first reported by Gratia and Jaumain", who also found that normal rabbit serum inhibits staphy phage,-in some instances to a titer. as high as 1: 500. More recently it has been observed (Rosenthal29, Raiga24 25, Biglieri and Fischer4, Applebaum and MacNeal2, Colvin8, and Evans"0) that normal human...

We have developed a rapid and reliable bacteriophage quantification method based on measurement of phage single-stranded DNA (ssDNA) using switchable lanthanide chelate complementation probes. One oligonucleotide probe contains a non-fluorescent lanthanide ion carrier chelate and another probe is labeled with a light absorbing antenna ligand. Hybridization of the non-fluorescent complementation...
