Name: Xanthomonas euvesicatoria Jones et al. 2006

Category: Species

Proposed as: sp. nov.

Etymology: Gr. adv. eû, well; L. fem. n. vesica, a blister; N.L. fem. adj. vesicatoria, causing a blister; N.L. fem. adj. euvesicatoria, intended to show that this bacterial species is most similar to the strains originally identified by E. M. Doidge 1921, which she designated Bacterium vesicatorium

Gender: feminine

Type strain: ATCC 11633; DSM 19128; ICMP 109; ICMP 98; LMG 27970; NBIMCC 8731; NCPPB 2968
