Izhakiella capsodis gen. nov., sp. nov., in the family Enterobacteriaceae, isolated from the mirid bug Capsodes infuscatus

Gram-stain-negative, oxidase-negative, facultatively anaerobic, motile, rod-shaped, non-pigmented bacterial strains (N6PO6 T , N8PO1 and N8PI1) were isolated from the mirid bug Capsodes infuscatus captured on Asphodelus aestivus plants. The 16S rRNA gene sequences of the strains shared 94.7-95.7 % similarity with species of the genus Pantoea and 95.6 % or less with species from other genera in the family Enterobacteriaceae . A polyphasic approach that included determination of phenotypic properties and phylogenetic analysis based on 16S rRNA, rpoB , gyrB and atpD gene sequences supported the classification of strains N6PO6 T , N8PO1 and N8PI1 as representing a novel species of a new genus in the family Enterobacteriaceae . Strain N6PO6 T , 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 C 16 : 0 , C 17 : 0 cyclo, C 18 : 1 ω7 c , summed feature 2 (C 14 : 0 3-OH and/or iso-C 16 : 1 I) and summed feature 3 (C 16 : 1 ω7 c and/or iso-C 15 : 0 2-OH). The DNA G+C content of strain N6PO6 T was 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 genus Izhakiella , in the family Enterobacteriaceae , for which the name Izhakiella capsodis gen. nov., sp. nov. is proposed. The type strain of Izhakiella capsodis is N6PO6 T ( = LMG 28430 T  = DSM 29293 T ).
