Analysis of the First Temperate Broad Host Range Brucellaphage (BiPBO1) Isolated from B. inopinata.

ABSTRACT: Brucella species are important human and animal pathogens. Though, only little is known about mobile genetic elements of these highly pathogenic bacteria. To date, neither plasmids nor temperate phages have been described in brucellae. We analyzed genomic sequences of various reference and type strains and identified a number of putative prophages residing within the Brucella chromosomes. By induction, phage BiPBO1 was isolated from Brucella inopinata. BiPBO1 is a siphovirus that infects several Brucella species including Brucella abortus and Brucella melitensis. Integration of the phage genome occurs adjacent to a tRNA gene in chromosome 1 (chr 1). The bacterial (attB) and phage (attP) attachment sites comprise an identical sequence of 46 bp. This sequence exists in many Brucella and Ochr
