Genomic characterization of three novel Basilisk-like phages infecting Bacillus anthracis.

ABSTRACT:

Background

In the present study, we sequenced the complete genomes of three novel bacteriophages v_B-Bak1, v_B-Bak6, v_B-Bak10 previously isolated from historical anthrax burial sites in the South Caucasus country of Georgia. We report here major trends in the molecular evolution of these phages, which we designate as "Basilisk-Like-Phages" (BLPs), and illustrate patterns in their evolution, genomic plasticity and core genome architecture.

Results

Comparative whole genome sequence analysis revealed a close evolutionary relationship between our phages and two unclassified Bacillus cereus group phages, phage Basilisk, a broad host range phage (Grose JH et al., J Vir. 2014;88(20):11846-11860) and phage PBC4, a highly host-restricted phage and close relative of Basilisk (Na H. e
