摘要
利用多核苷酸序列亲缘关系测定肺炎克雷伯菌和阴沟肠杆菌标记的DNA与未标记的产气大肠杆菌和氧化克雷伯菌DNA的差异程度。14株产气大肠杆菌与1株肺炎克雷伯菌和1株阴沟大肠杆菌的DNA同源性分别为53%±3和39%±4。同样，11株脱氧梭菌的未标记DNA与肺炎克雷伯菌和阴沟克雷伯菌的标记DNA分别具有55%±4和40%±3的DNA相关性。因此，应将产气大肠杆菌归入克雷伯氏菌属，并按Bascomb et al.(1971)提出的命名为克雷伯氏菌(Klebsiella mobilis)。
Contribution of DNA-DNA Hybridization to the Transfer of Enterobacter aerogenes to the Genus Klebsiella as K. mobilis
Polynucleotide sequence relatedness reactions were carried out to determine the extent of DNA divergence between labelled DNA of Klebsiella pneumoniae and Enterobacter cloacae and unlabelled DNA of E. aerogenes and K. oxytoca. DNA homology between 14 strains of E. aerogenes and one strain of K. pneumoniae and one strain of E. cloacae was 53% ± 3 and 39% ± 4 respectively. Similarly, unlabelled DNA from 11 strains of K. oxytoca exhibited 55% ± 4 and 40% ± 3 DNA relatedness with labelled DNA of K. pneumoniae and E. cloacae respectively. It is concluded that E. aerogenes should be classified in the genus Klebsiella with the denomination of Klebsiella mobilis as previously proposed by Bascomb et al. (1971).
