巴尔通体(Bartonella species)是一群革兰氏染色阴性、难于培养的兼性胞内寄生菌,21个种及亚种,其中9种可致人类疾病。20世纪90年代以后,在欧美地区的一些流浪人群中出现了菌血症、心内膜炎,一些艾滋病人群中出现了杆菌性血管瘤等由巴尔通体引发的疾病,被世界卫生组织(WHO)确认为新发传染病,对巴尔通体及其疾病的研究也引起了人们的关注。由于巴尔通体生长缓慢、生化反应不活泼,表型鉴定的方法不能应用于巴尔通体的分类鉴定中,因此多基因序列系统发育分析是鉴定巴尔通体的唯一
Bartonella species is a group of Gram-negative, difficult-to-develop, facultative intracellular parasites, 21 species and subspecies, of which 9 are human diseases. Bacteria, endocarditis, bacteriological hemangiomas and other diseases caused by Bartonella occur in some of the AIDS patients in the 1990s after the 1990s in some of the vagabonds in Europe and the United States. The disease was reported by the World Health Organization (WHO) Confirmed as a new infectious disease, Bartonella and its disease research has also attracted people’s attention. Due to the slow growth of Bartonella and the biochemical reaction, the phenotypic identification method can not be applied to the taxonomic identification of Bartonella, so phylogenetic analysis of multiple gene sequences is the only way to identify Bartonella
