title: Izhakiella capsodisgen. nov., sp. nov., in the familyEnterobacteriaceae, isolated from the mirid bugCapsodes infuscatus.
abstract: Gram-stain-negative, oxidase-negative, facultatively anaerobic, motile, rod-shaped, non-pigmented bacterial strains (N6PO6T, N8PO1 and N8PI1) were isolated from the mirid bugCapsodes infuscatuscaptured onAsphodelus aestivusplants. The 16S rRNA gene sequences of the strains shared 94.7-95.7 % similarity with species of the genusPantoeaand 95.6 % or less with species from other genera in the familyEnterobacteriaceae. A polyphasic approach that included determination of phenotypic properties and phylogenetic analysis based on 16S rRNA,rpoB,gyrBandatpDgene sequences supported the classification of strains N6PO6T, N8PO1 and N8PI1 as representing a novel species of a new genus in the familyEnterobacteriaceae. Strain N6PO6T, and the two reference strains of the novel species, grew at 1-37 °C, and in the presence of NaCl (up to 7.5 %, w/v) and sucrose (up to 60 %). Their major cellular fatty acids were C16 : 0, C17 : 0cyclo, C18 : 1ω7c, summed feature 2 (C14 : 03-OH and/or iso-C16 : 1I) and summed feature 3 (C16 : 1ω7cand/or iso-C15 : 02-OH). The DNA G+C content of strain N6PO6Twas 49.9 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, the mirid bug isolates are classified as representing a novel species in a new genusIzhakiella, in the familyEnterobacteriaceae, for which the nameIzhakiella capsodisgen. nov., sp. nov. is proposed. The type strain ofIzhakiella capsodisis N6PO6T( = LMG 28430T= DSM 29293T).
