(A) Itr-based classification of 237 A. baumannii KL-/K-types. (B) Pie chart showing the statistics of each initializing transferase. Note that ItrB4 (KL75) and ItrB2 along with ItrA2 (KL115 and KL222) are not marked in (B) due to the less frequency of cps loci possessing them. Note that Leg5Ac7Ac (or its derivatives) are observed in the K-antigen repeating units that are grouped under the initiating glycosyl transferase ItrA3 & ItrB2.
