A fastidious, slowly growing, strictly aerobic, gram-negative bacterium was isolated from a culture of blood from a 25-year-old man with common variable immunodeficiency. The man had been admitted to hospital with febrile progressive cerebellar ataxia. The use of standard phenotypic schemes did not lead to identification, but sequence analysis demonstrated that the 16S rRNA gene of the isolate was most similar to those of the environmental bacteria Duganella zoogloeoides (formerly Zoogloea ramigera 115) and Telluria mixta. Further characterization of the bacterium by biochemical analysis, electron microscopy, G+C content estimation, and fatty acid analysis demonstrated significant differences between the bacterium and D. zoogloeoides and Telluria species; thus, we propose it as a new taxon with the name Massilia timonae gen. nov., sp. nov.
从一名患有常见可变免疫缺陷的25岁男性的血液培养物中分离出一种苛求、生长缓慢、严格需氧的革兰氏阴性细菌。该男子因发热性进行性小脑共济失调入院。使用标准表型分类方法未能鉴定出该细菌,但序列分析表明,分离株的16S rRNA基因与环境细菌佐氏动胶菌(以前称为枝状动胶菌115)和混合地杆菌的16S rRNA基因最为相似。通过生化分析、电子显微镜、G+C含量测定和脂肪酸分析对该细菌进行进一步鉴定,结果表明该细菌与佐氏动胶菌和地杆菌属存在显著差异;因此,我们将其提议为一个新的分类单元,命名为蒂莫纳马赛菌属,新种。
