Birds are known to be carriers of ticks infected by tick-borne pathogens, including bacteria. However, not many studies have been carried out on avian tissues to detect these agents. The aim of the present survey was to investigate, using PCR, the presence of , spp., sensu lato, , , , , and spp. in the spleens collected from 300 wild birds of different orders and species from Central Italy. A total of 53 (17.67%) samples were PCR positive for at least one investigated pathogen. One (0.33%) bird was positive for spp., five (1.67%) birds were positive for , eleven (3.67%) for s.l., and thirty-six (12%) for No coinfection was detected. All samples were negative for , , , and spp. The findings showed that wild birds may harbor different zoonotic tick-borne bacteria; therefore, they can contribute to the diffusion of these agents.
众所周知，鸟类是感染蜱传病原体（包括细菌）的蜱虫的携带者。然而，针对禽类组织检测这些病原体的研究并不多。本次调查的目的是利用聚合酶链反应（PCR），检测从意大利中部300只不同目和物种的野生鸟类脾脏中是否存在嗜吞噬细胞无形体（Anaplasma phagocytophilum）、狭义伯氏疏螺旋体（Borrelia burgdorferi sensu stricto）、广义巴贝斯虫（Babesia spp.）、犬埃立克体（Ehrlichia canis）、新型立克次体（Neorickettsia spp.）、伯氏考克斯体（Coxiella burnetii）和巴尔通体（Bartonella spp.）。共有53份（17.67%）样本至少对一种调查的病原体呈PCR阳性。一只（0.33%）鸟对嗜吞噬细胞无形体呈阳性，五只（1.67%）鸟对狭义伯氏疏螺旋体呈阳性，十一只（3.67%）对广义巴贝斯虫呈阳性，三十六只（12%）对犬埃立克体呈阳性，未检测到混合感染。所有样本对新型立克次体、伯氏考克斯体、巴尔通体和狭义伯氏疏螺旋体均为阴性。研究结果表明，野生鸟类可能携带不同的人兽共患蜱传细菌；因此，它们可能有助于这些病原体的传播。
