Phenotypic and phylogenetic studies were performed on a Gram-negative, rod-shaped bacterium isolated from three porpoises. Biochemical and physiological studies indicated that the bacterium was related to the family Pasteurellaceae. Comparative 16S rRNA gene sequencing studies confirmed these findings and demonstrated that the bacterium represents a hitherto unknown subline. The nearest phylogenetic relative of the unknown bacterium was Actinobacillus delphinicola, an organism also originating from sea mammals, although a sequence divergence of 3% demonstrated that the newly isolated bacterium is a distinct species. On the basis of the results of the phylogenetic analysis and phenotypic criteria, it is proposed that the bacterium should be classified as a new species, Actinobacillus scotiae sp. nov. The type strain of Actinobacillus scotiae sp. nov. is NCTC 12922T (= M2000/95/1T).
对从三头鼠海豚分离出的革兰氏阴性杆状细菌进行了表型和系统发育研究。生化和生理学研究表明，该细菌与巴斯德氏菌科有关。比较16S rRNA基因测序研究证实了这些发现，并表明该细菌代表一个迄今未知的亚系。未知细菌最近的系统发育亲缘种是海豚放线杆菌，一种也起源于海洋哺乳动物的生物，尽管3%的序列差异表明新分离的细菌是一个独特的物种。根据系统发育分析结果和表型标准，建议将该细菌分类为一个新物种，即苏格兰放线杆菌新种。苏格兰放线杆菌新种的模式菌株是NCTC 12922T（= M2000/95/1T）。
