国际上对于弧菌科弧菌属的分类有两种方法。一种是将弧菌分为 OI 群霍乱弧菌,不典型 OI 型霍乱弧菌,非 OI 群霍乱弧菌和其他弧菌。另一种是按细菌分类学的方法,如“伯杰氏细菌学分类手册”(第一版1984)将弧菌属的细菌分为20个种或亚种...国际上对于弧菌科弧菌属的分类有两种方法。一种是将弧菌分为 OI 群霍乱弧菌,不典型 OI 型霍乱弧菌,非 OI 群霍乱弧菌和其他弧菌。另一种是按细菌分类学的方法,如“伯杰氏细菌学分类手册”(第一版1984)将弧菌属的细菌分为20个种或亚种。我们对14株不凝集弧菌用常规方法和 V—18B 细菌快速生化鉴定系统进行鉴定,其结果为梅契尼柯夫弧菌(V.metsehnikovu)。现报告如下:展开更多

In this study we pay special attention to the phylogenetic positions of 56 Archaea genomes among which 7 species have not been listed either in Bergey’s Manual of Systematic Bacteriology or in Taxonomic Outline of Bacteria and Archaea (TOBA). By inspecting the stable monophyletic branchings in CVTrees reconstructed from a total of 861 genomes (56 Archaea plus 797 Bacteria, using 8 Eukarya as outgroups) definite taxonomic assignments were proposed for these not-fully-classified species. Further development of Archaea taxonomy may verify the predicted phylogenetic results of the CVTree approach.展开更多
