Antimicrobial drug-selection markers for Burkholderia pseudomallei and B. mallei.
Schweizer HP., Peacock SJ.
Genetic research into the select agents Burkholderia pseudomallei and B. mallei is currently hampered by a paucity of approved antimicrobial drug-selection markers. The strict regulations imposed on researchers in the United States but not in other parts of the world lead to discrepancies in practice, hinder distribution of genetically modified strains, and impede progress in the field. Deliberation and decisions regarding alternative selection markers (antimicrobial and nonantimicrobial drugs) by the international community, regulatory authorities, and funding agencies are needed.
