characterization of vibrio cholerae bacteriophage k139 and use of a novel mini-transposon to identify a phage-encoded virulence factor.temperate bacteriophage k139 was isolated from a vibrio cholerae o139 isolate and characterized in this study. the phage genome consists of a 35 kbp, double-stranded, linear dna molecule that circularizes and integrates into the chromosome in a site-specific manner. dna sequences that cross-hybridize with k139 phage dna are present in all strains of v. cholerae serogroup o1 of the classical biotype examined and in some strains of the el tor biotype. phage k139 produces plaques on el tor o1 strai ...19958817491
temperate bacteriophage phio18p from an aeromonas media isolate: characterization and complete genome sequence.a group of 74 aeromonas isolates from surface water of three ponds in bielefeld, germany was screened for prophage induction after uv irradiation. the phage phio18p was induced from the aeromonas media isolate o18. phio18p belongs to the myoviridae phage family. the complete nucleotide sequence of the double stranded dna genome of bacteriophage phio18p consists of 33,985 bp. the genome has 5' protruding cohesive ends of 16 bases. on the phio18p genome 46 open reading frames (orfs) were identifie ...200818096197
[role of moderate bacteriophage 139 in change in production of cholera toxin in a classic strain of vibrio cholerae].new data were obtained concerning cell sensitivity of pathogenic strains of cholera vibrions, which belong to the serogroup o1 of classical biovar, to the temperate bacteriophage k139, the native host of which is vibrio cholerae o139. molecular-genetic and biochemical studies showed that phage 139 integrated into the chromosome of strains v. cholerae o1 can change their toxigenic properties. a change in the production of cholera toxin (ct) in lysogens is associated both with an increase in the a ...200415174276
