pseudomallei),

albeit loosely related. Further work that includes prophages derived from environmental and clinical isolates from other Burkholderia species as well as from other microbes is needed to refine these relationships. Burkholderia Mocetinostat spp. are responsible for a number of potentially devastating infectious diseases for which no vaccines currently exist. The presence of a wide variety of bacteriophages within these bacteria opens the possibility that phage therapy may be developed to augment present antibiotic treatments. We present here a detailed comparative analysis of gene content within and between groups of bacteriophages, putative prophages, and prophage-like regions in BMS202 purchase various Burkholderia species and strains. Several interesting genes and gene groups associated with pathogenicity and various metabolic functions were identified within specific groups. This study provides the first estimate of the relative contribution of prophages to the vast phenotypic diversity found among the Burkholderiae.
