Drop test of the enzyme was made in bacterial lawns of a collection of A. baumannii strains with known capsular types. For all strains, the sequence types (ST) according the multilocus sequence analysis using the Pasteur scheme, capsular type (K), and respective accession numbers are given. K type, determined capsule structure; NA, not available.
