Bartonella species are fastidious bacteria that predominantly infect mammalian erythrocytes and endothelial cells and cause long-lasting bacteraemia in their reservoir hosts. Reports that describe the epidemiology of bartonellosis in Brazil are limited. This study aimed to detect and characterise Bartonella spp DNA from cat blood samples in São Luís, Maranhão, north-eastern Brazil. Among 200 cats tested for multiple genes, nine (4.5%) were positive for Bartonella spp: six cats for Bartonella henselae and three for Bartonella clarridgeiae. Based on the phylogenetic analysis of four genes, the B. henselae strain matched strains previously observed in Brazil and was positioned in the same clade as B. henselae isolates from the United States of America. Moreover, sequence alignment demonstrated that the B. clarridgeiae strain detected in the present study was the same as the one recently detected in cats from southern Brazil.
巴尔通体物种是一种挑剔的细菌，主要感染哺乳动物的红细胞和内皮细胞，并在其储存宿主中引起持久的菌血症。描述巴西巴尔通体病流行病学的报告有限。本研究旨在检测和鉴定来自巴西东北部马拉尼昂州圣路易斯的猫血液样本中的巴尔通体属 DNA。在检测的 200 只猫中，有 9 只为巴尔通体属阳性（4.5%）：6 只为亨氏巴尔通体，3 只为克拉里吉氏巴尔通体。基于对 4 个基因的系统发育分析，亨氏巴尔通体菌株与巴西以前观察到的菌株相匹配，并与来自美国的亨氏巴尔通体分离株位于同一进化枝。此外，序列比对表明，本研究中检测到的克拉里吉氏巴尔通体菌株与最近在巴西南部猫中检测到的菌株相同。
