The counter-selectable marker sacB, commonly used in gram-negative bacteria, is nonselective on sucrose in many Burkholderia species." "In addition, the use of antibiotic resistance markers of clinical importance for the selection of desirable genetic traits is prohibited in the United States for two potential bioterrorism agents, Burkholderia mallei and Burkholderia pseudomallei. Here, we engineered a mutated counter-selectable marker based on the B. pseudomallei PheS (the...
