The Gram-negative bacterial genus Xanthomonas includes numerous infra-specific taxa known as pathovars, which are defined primarily on host range and disease symptoms. With the advent of molecular sequence data, many pathovars have been transferred from X. campestris into other Xanthomonas species to better harmonise taxonomy and phylogeny. We performed whole-genome shotgun sequencing on pathotype strains of the following X. campestris pathovars: blepharidis, carissae, clerodendri, convolvuli, coriandri, daturae, euphorbiae, fici, heliotropii, ionidii, lawsoniae, mirabilis, obscurae, paulliniae, pennamericanum, spermacoces, uppalii, vernoniae, viegasii and zingibericola. These genomes showed more than 98% average nucleotide identity with the type-strain of X. euvesicatoria and less than 88% with the type-strain of X. campestris. We propose the transfer of these pathovars into X. euvesicatoria and present an emended species description for X. euvesicatoria.
