Allelic variations of Blp1 among the strains of two major A. baumannii pandemic clones. a – an alignment of Blp1 sequences in A. baumannii IC I and IC II strains, available in NCBI Genbank; black areas indicate 100% identity, variable regions are in grey and the absence of the region is indicated by the thin strip; numbers demonstrate the position of amino acids; alignment was prepared using TexShade tool. b – organization of Blp1 protein domains in representative strains of IC I (AYE) and IC II (AB_1656–2) clonal lineages.; green and red boxes represent bacterial immunoglobulin-like 3_2 type (Big_3_2), and immunoglobulin-like 6 type (Big_6) domains, respectively, blue boxes represent RTX domains; domain organization was identified using HHMER tool
