巴尔通体菌种会导致人类发生严重的临床综合征。引起大部分感染的 3 种最主要病原体分别为汉赛巴尔通体、五日热巴尔通体和杆菌样巴尔通体。
某些种属广泛分布于世界各地（汉赛巴尔通体），而其他种属通常呈局部分布（杆菌样巴尔通体）。
巴尔通体经直接接触（汉赛巴尔通体经猫咬伤或抓伤）或经昆虫媒介（五日热巴尔通体经虱子、杆菌样巴尔通体经沙蝇）从受感染的自然宿主向易感人类宿主传播。
巴尔通体可感染红细胞，造成血管增生，导致久热不退、淋巴结肿大以及肝脾肿大。
通过培养、血清学或组织病理学确立实验室诊断。若有条件，可采用分子学技术（例如聚合酶链反应），对血液和组织样本（包括心脏瓣膜）检查十分有用。
根据巴尔通体种属及临床表现类型进行治疗，但是通常包含抗生素治疗。对于某些病例（例如猫抓病），可能需进行针吸活检。
人类巴尔通体病由巴尔通体造成，巴尔通体是一兼性胞内寄生种属。自 1993 年以来，现已发现 45 种巴尔通体种属，据报道，其中部分种属可造成人类感染。[1]Jacomo V, Kelly PJ, Raoult D. Natural history of Bartonella infections (an exception to Koch's postulate). Clin Diagn Lab Immunol. 2002 Jan;9(1):8-18.

在人类中已描述的三种最常见感染包括：猫抓病（汉赛巴尔通体）；Carrion 病（杆菌样巴尔通体；该疾病包括菌血症阶段 [奥罗亚热] 和出疹阶段 [秘鲁疣]）；以及战壕热（五日热巴尔通体）。[4]Anderson BE, Neuman MA. Bartonella spp. as emerging human pathogens. Clin Microbiol Rev. 1997 Apr;10(2):203-19.

巴尔通体引起的临床综合征范围广泛，包括：不明原因久热不退、血液学表现、脑炎和脑病、全身性淋巴结肿大、肝脾病变、视网膜病、培养阴性心内膜炎、骨髓炎、关节炎、纵隔肿块和胸膜炎。[4]Anderson BE, Neuman MA. Bartonella spp. as emerging human pathogens. Clin Microbiol Rev. 1997 Apr;10(2):203-19.
