The description is the same as the species. Additionally, the Biolog GEN III and PM02A MicroPlates revealed the ability of strain LMG 938neoPT to utilize β-gentiobiose, glycerol, pectin, l-lactic acid, tween 40, α-keto-butyric acid, acetoacetic acid, sodium formate, gelatin, laminarin, d-raffinose, N-acetyl-l-glutamic acid, weakly utilize l-tartaric acid, and grow in presence of 4% NaCl, tetrazolium violet, tetrazolium blue, potassium tellurite and sodium bromate. The Biolog PM03B MicroPlates indicated that l-alanine, l-arginine, l-glutamic acid, l-glutamine, l-ornithine, glucuronamide, d-glucosamine, N-acetyl-d-glucosamine, guanine, xanthosine, uric acid, alanyl-glutamine, alanyl-glutamic acid and glycyl-glutamic acid can be used as nitrogen sources. The primary host is the lettuce (Lactuca sativa L.). The pathotype strain of X. campestris pv. vitians (Brown 1918) Vauterin et al. 1995 CFBP 2538PT = LMG 937PT = NCPPB 976PT = ICMP 336PT = ATCC 19320PT has been proven to be non-pathogenic on lettuce, phenotypically and genotypically different from all other bacterial leaf spot of lettuce-related strains, as discussed in the present study and in previous ones [3], [53], [62]. Therefore, in accordance with Standards 9–4 and 11 of the International Standards for Naming Pathovars of Phytopathogenic Bacteria [15], [75], we propose the replacement of this pathotype by neopathotype strain LMG 938neoPT = CFBP 8686neoPT = NCPPB 2248neoPT. We propose that its subsequent transfer to X. hortorum be as X. hortorum pv. vitians (Brown 1918) Vauterin et al. 1995 comb. nov. in part to ensure the conservation of the priority established by Nellie Brown. However, if the neopathotype is rejected, we propose that this same name be established as X. hortorum pv. vitians pv. nov. The GenBank accession number for its genome assembly is GCA_012922135.1.

Neopathotype strain LMG 938^neoPT = CFBP 8686^neoPT = NCPPB 2248^neoPT.
