St.Louis encephalitis virus (SLEV) is an emerging human pathogen flavivirus in Argentina. Recently, it has reemerged in the United States. We evaluated the role as amplifying host of six resident bird species and analyzed their capacity as host during the 2005 encephalitis outbreak of SLEV in Córdoba. Eared Dove, Picui Ground Dove, and House Sparrow were the three species with highest host competence index. At a city level, Eared Dove and Picui Ground Dove were the most important amplifying hosts during the 2005 SLEV human outbreak in Córdoba city. This finding highlighted important differences in the SLEV ecology between Argentina and the United States. Characterizing and evaluating the SLEV hosts contribute to our knowledge about its ecology and could help us to understand the causes that promote its emergence as a human pathogen in South America.
圣路易斯型脑炎病毒(SLEV)是阿根廷的一种新兴人类病原体黄病毒。最近,它在美国再次出现。我们评估了六种常驻鸟类作为扩增宿主的作用,并在 2005 年科尔多瓦 SLEV 脑炎爆发期间分析了它们作为宿主的能力。棕腹鸽、皮丘地鸽和家麻雀是宿主能力指数最高的三个物种。在城市层面上,棕腹鸽和皮丘地鸽是 2005 年科尔多瓦市 SLEV 人类爆发期间最重要的扩增宿主。这一发现强调了阿根廷和美国之间 SLEV 生态的重要差异。描述和评估 SLEV 的宿主有助于我们了解其生态学,并帮助我们理解导致其在南美洲成为人类病原体的原因。
