VB_BcM_Sam46 and vB_BcM_Sam112, members of a new bacteriophage genus with unusual small terminase structure.

ABSTRACT: One of the serious public health concerns is food contaminated with pathogens and their vital activity products such as toxins. Bacillus cereus group of bacteria includes well-known pathogenic species such as B. anthracis, B. cereus sensu stricto (ss), B. cytotoxicus and B. thuringiensis. In this report, we describe the Bacillus phages vB_BcM_Sam46 and vB_BcM_Sam112 infecting species of this group. Electron microscopic analyses indicated that phages Sam46 and Sam112 have the myovirus morphotype. The genomes of Sam46 and Sam112 comprise double-stranded DNA of 45,419 bp and 45,037 bp in length, respectively, and have the same GC-content. The genome identity of Sam46 and Sam112 is 96.0%, indicating that they belong to the same phage species. According to the phylogenetic analysis, these phage
