Updated Analysis of the Surface Carbohydrate Gene Clusters in a Diverse Panel of Acinetobacter baumannii Isolates.

ABSTRACT

To enhance the utility of the genetically diverse panel of Acinetobacter baumannii isolates reported recently by Galac and coworkers (M. R. Galac, E. Snesrud, F. Lebreton, J. Stam, et al., Antimicrob Agents Chemother 64e00840-20, 2020, https//doi.org/10.1128/AAC.00840-20) and to identify the novel KL and OCL, all of the gene clusters that direct the biosynthesis of capsular polysaccharide and of the outer core of lipooligosaccharide, respectively, were reexamined. The nine KL and one OCL previously recorded as novel were identified, and nine further novel KL and two OCL were found.
