Four strains of budding, hyphal bacteria, which had very similar chemotaxonomic properties, were isolated from the Baltic Sea. The results of DNA-DNA hybridization experiments, indicated that three of the new isolates were closely related, while the fourth was only moderately related to the other three. Sequence signature and higher-order structural detail analyses of the 16S rRNA of strain IFAM 1418T (T = type strain) indicated that this isolate is related to the alpha subclass of the class Proteobacteria. Although our isolates resemble members of the genera Hyphomicrobium and Hyphomonas in morphology, assignment to either of these genera was excluded on the basis of their markedly lower DNA guanine-plus-cytosine contents. We propose that these organisms should be placed in a new genus, Hirschia baltica is the type species of this genus, and the type strain of H. baltica is strain IFAM 1418 (= DSM 5838).
从波罗的海分离出了四株具有相似化学分类学特性的出芽、菌丝状细菌。DNA-DNA杂交实验结果表明，其中三株新分离株关系密切，而第四株与其他三株仅有中度相关性。对菌株IFAM 1418T（T = 模式菌株）的16S rRNA进行序列特征和高级结构细节分析表明，该分离株与变形菌纲的α亚类相关。尽管我们的分离株在形态上类似于生丝微菌属和生丝单胞菌属的成员，但基于它们明显较低的DNA鸟嘌呤加胞嘧啶含量，排除了将其归入这两个属中的任何一个。我们建议将这些生物置于一个新属中，波罗的海赫氏菌（Hirschia baltica）是该属的模式种，波罗的海赫氏菌的模式菌株是菌株IFAM 1418（= DSM 5838）。
