Molecular methods were used to detect and identify Bartonella species in the cat fleas Ctenocephalides felis felis from Puerto Iguazú, a border area in northeastern Argentina. The fleas were collected from 12 household animals, 9 dogs (Canis lupus familiaris) and 3 cats (Felis silvestris catus) during July 2016. Out of 15C. f. felis analyzed for PCR, only one flea collected from a cat was positive (6.66%) in screened for Bartonella spp. based on the gltA gene. Bartonella clarridgeiae was identified in the genetic analyses, this specimen clustered monophyletically with others B. clarridgeiae isolated from different geographical origins (1.0 PP), even, all shared the same haplotype. The results obtained provide evidence of the presence of B. clarridgeiae in cat fleas from Argentina suggesting the probable presence of related flea-borne diseases in the region and the role of cat fleas in the transmission of Bartonella among mammals including humans.
采用分子方法检测并鉴定了来自阿根廷东北部边境地区伊瓜苏港的猫栉首蚤（Ctenocephalides felis felis）中的巴尔通体物种。2016 年 7 月，从 12 只家庭饲养的动物（9 只狗和 3 只猫）中采集了这些跳蚤。在对 15 只 C. f. felis 进行 PCR 分析时，仅从一只猫身上采集的一只跳蚤（6.66%）基于 gltA 基因呈巴尔通体 spp.阳性。在基因分析中鉴定出了贝氏柯克斯体，该标本与从不同地理来源分离的其他 B. clarridgeiae 分离株聚为单系（1.0 PP），甚至所有分离株都具有相同的单倍型。这些结果表明，阿根廷的猫栉首蚤中存在 B. clarridgeiae，这表明该地区可能存在与跳蚤传播相关的疾病，以及猫栉首蚤在包括人类在内的哺乳动物中传播巴尔通体的作用。
