An outbreak of Xylella fastidiosa was discovered in late 2018 in northern Italy affecting several plant species. Multilocus sequence typing analyses detected the presence of strains clustering in X. fastidiosa subsp. multiplex and harboring a hitherto uncharacterized sequence type, ST87. Three cultured strains (TOS4, TOS5, and TOS14) were subjected to high-throughput sequencing and the draft genomes assembled. Phylogenetic analysis conclusively indicated that they belong to the subspecies multiplex. The genetic information generated for these newly discovered strains further supports the evidence that sequence types are associated with the emergence of X. fastidiosa in Europe, posing major challenges for predicting the main threatened European and Mediterranean crops and plant species.
