Morbidity and mortality associated with adenoviruses (AdVs) have been reported in multiple taxa, including chelonians. Adenoviruses of a distinct testudinoid origin have been detected in both managed and free-ranging turtles in North America and Europe; however, the prevalence and impact of AdVs in free-ranging turtle populations have yet to be determined. A multispecies investigation to detect novel or existing AdVs in Blanding's turtles (Emydoidea blandingii; n=1,359), painted turtles (Chrysemys picta; n=270), and red-eared sliders (Trachemys scripta elegans; n=205) was performed across four counties in Illinois (with one site reaching into Wisconsin), USA, from 2016 to 2022. Sequence-confirmed AdVs were detected in Blanding's turtles (1.8%; n=24), painted turtles (13.0%; n=35), and red-eared sliders (8.8%; n=18). Ten AdVs, including 5 novel AdVs, were detected across the three species, with each species having 3-6 AdVs detected. Three AdVs were probably prey related, whereas the remaining seven AdVs were probably host-adapted AdVs, based on the absence of clinical signs of disease. The majority of AdVs detected were testadenoviruses; however, the siadenovirus Sulawesi tortoise adenovirus (STADV) was sequence confirmed in 1 Blanding's turtle, 15 painted turtles, and 10 red-eared sliders, all of which were free of clinical signs of disease. These results provide a baseline for the presence and diversity of AdVs in free-ranging turtles in Illinois, including evidence for a North American reservoir for STADV.
在包括龟类在内的多个分类群中，都有腺病毒（AdV）相关的发病和死亡报道。在北美和欧洲的人工饲养及野生龟类中，均检测到了具有独特陆龟类起源的腺病毒；然而，腺病毒在野生龟类种群中的流行率和影响尚未确定。2016年至2022年期间，在美国伊利诺伊州的四个县（其中一个地点延伸至威斯康星州），对布兰丁龟（Emydoidea blandingii；n = 1359只）、彩龟（Chrysemys picta；n = 270只）和红耳龟（Trachemys scripta elegans；n = 205只）进行了一项多物种调查，以检测新的或现有的腺病毒。在布兰丁龟（1.8%；n = 24只）、彩龟（13.0%；n = 35只）和红耳龟（8.8%；n = 18只）中检测到了经序列确认的腺病毒。在这三个物种中总共检测到10种腺病毒，其中包括5种新的腺病毒，每个物种检测到3 - 6种腺病毒。基于没有疾病临床症状，3种腺病毒可能与猎物有关，而其余7种腺病毒可能是宿主适应性腺病毒。检测到的大多数腺病毒是陆龟腺病毒；然而，在1只布兰丁龟、15只彩龟和10只红耳龟中经序列确认检测到了丝腺病毒苏拉威西陆龟腺病毒（STADV），所有这些龟均没有疾病临床症状。这些结果为伊利诺伊州野生龟类中腺病毒的存在和多样性提供了基线，包括北美存在STADV储存库的证据。
