Characterization of the first Pseudomonas grimontii bacteriophage, PMBT3.
The complete genome sequence of the virulent bacteriophage PMBT3, isolated on the proteolytic Pseudomonas grimontii strain MBTL2-21, showed no significant similarity to other known phage genome sequences, making this phage the first reported to infect a strain of P. grimontii. Electron microscopy revealed PMBT3 to be a member of the family Siphoviridae, with notably long and flexible whiskers. The linear, double-stranded genome of 87,196 bp has a mol% G+C content of 60.4 and contains 116 predicted protein-encoding genes. A putative tellurite resistance (terB) gene, originally reported to occur in the genome of a bacterium, was detected in the genome of phage PMBT3.
