A total of 56 fleas were collected from mice, rats, and one hedgehog in national parks of mainland Portugal and the Madeira Island. All fleas were tested for the presence of bacteria of the genera Rickettsia and Bartonella using PCR assays. In fleas from mainland Portugal, we detected Rickettsia felis in one Archaeopsylla erinacei maura flea and in one Ctenophtalmus sp. In five Leptopsylla segnis fleas taken from rats in the Madeira Island, we identified Rickettsia typhi. In addition, in four fleas from the genera Ornithophaga and Stenoponia collect from mice and a rat in mainland Portugal, we detected the presence of two new Bartonella genotypes closely related to Bartonella elizabethae. Our findings emphasize the potential risk of flea-transmitted infections in mainland Portugal and the Madeira archipelago, and extend our knowledge of the potential flea vectors of human pathogens.
在葡萄牙大陆和马德拉岛的国家公园中，共从老鼠、大鼠和一只刺猬身上采集了56只跳蚤。使用聚合酶链式反应（PCR）检测所有跳蚤是否存在立克次氏体属和巴尔通体属细菌。在来自葡萄牙大陆的跳蚤中，我们在一只刺鼠蚤指名亚种跳蚤和一只栉眼蚤属跳蚤中检测到了猫立克次氏体。在从马德拉岛的大鼠身上采集的五只缓慢细蚤跳蚤中，我们鉴定出了鼠型斑疹伤寒立克次氏体。此外，在从葡萄牙大陆的小鼠和一只大鼠身上采集的四只鸟蚤属和窄蚤属跳蚤中，我们检测到存在两种与伊丽莎白巴尔通体密切相关的新型巴尔通体基因型。我们的研究结果强调了葡萄牙大陆和马德拉群岛存在跳蚤传播感染的潜在风险，并扩展了我们对人类病原体潜在跳蚤传播媒介的认识。
