Acinetobacter baumannii is an emerging pathogen that causes serious infections with high mortality rates in immunocompromised individuals. Genetic manipulations in this medically-relevant pathogen are limited by the paucity of molecular tools. In this study, we show the application of the mini-Tn. 7-based single copy insertion system in A. baumannii. Mini-Tn. 7 elements are known to integrate at a naturally evolved, therefore presumably neutral location (intergenic region) downstream of the glmS gene (glucosamine-fructose-6-phosphate aminotransferase) in Gram-negative bacteria. We identified the site of insertion of mini-Tn. 7 in A. baumannii and demonstrated application of this useful cloning tool by inserting the gfp gene into the chromosome. Our work shows that mini-Tn 7 elements are useful tools for genetic studies in this important pathogen.
