Abstract
A Gram-negative, aerobic, motile, spiral-shaped bacterium, strain H5569(T), was isolated from a human blood sample. Phenotypic and molecular characteristics of the isolate were investigated. Optimal growth was found to occur at 35 °C under aerobic conditions on Heart Infusion Agar supplemented with 5 % rabbit blood. The major fatty acids present in the cells were identified as C16:0, C16:1ω7c and C18:1ω7c. The predominant respiratory quinone was found to be ubiquinone-Q10. The G+C content of genomic DNA for strain H5569(T) was found to be 49.9 %. Based on 16S rRNA gene sequence analysis results, 13 additional isolates were also analysed in this study. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism, represented by strain H5569(T), forms a distinct lineage within the family Rhodospirillaceae, closely related to two Novispirillum itersonii subspecies (93.9-94.1 %) and two Caenispirillum sp. (91.2-91.6 %). Based on these results, the isolate H5569(T) is concluded to represent a new genus and species for which the name Haematospirillum jordaniae gen. nov., sp. nov. is proposed. The type strain is H5569(T) (=DSM(T) 28903 = CCUG 66838(T)).
