Abstract

Free-roaming rosy-faced lovebirds (Agapornis roseicollis) were first documented in the greater Phoenix area (Arizona, USA) in the mid-1980s and have since established small populations. In blood and cloacal swab samples from 69 lovebirds at four locations, we identified the presence of beak and feather disease virus (BFDV), aves polyomavirus (APyV), and psittacine adenovirus 5 (PsAdV-5). Additionally, we identified a novel aviadenovirus, hereby referred to as psittacine adenovirus 12 (PsAdV-12). PsAdV-12 is most closely related to members of the species Aviadenovirus senegalense and Aviadenovirus rubri, sharing ∼64 % genome-wide pairwise identity. Incidence of each virus across all lovebirds varied, with BFDV being the highest at 68.1 % overall, whereas a much lower infection rate was observed for APyV (8.6 %), PsAdV-5 (5.7 %), and PsAdV-12 (2.8 %). Our analysis supports an introduction of BFDV-infected lovebirds into the greater Phoenix area in the 1980s followed by radiation to three circulating distinct lineages; APyVs showed very little diversification.

圆环病毒、多瘤病毒和腺病毒在美国亚利桑那州凤凰城自由漫游的红脸爱情鸟中的发病率和多样性

自由漫游的红脸爱情鸟（Agapornis roseicollis）于20世纪80年代中期在大凤凰城地区（美国亚利桑那州）首次被记录下来，并从此建立了小规模的种群。在四个地点的69只情侣鸟的血液和肛肠拭子样本中，我们发现了鸟喙和羽毛病病毒（BFDV）、鸟多瘤病毒（APyV）和鹦鹉腺病毒5 （PsAdV-5）。此外，我们鉴定出一种新的鸟腺病毒，在此称为鹦鹉腺病毒12 （psadv12）。PsAdV-12与senegalense鸟腺病毒和rubri鸟腺病毒最密切相关，具有64%的全基因组两两同源性。每种病毒在所有情侣中的发病率各不相同，其中BFDV的感染率最高，为68.1%，而APyV（8.6%）、psadv5（5.7%）和psadv12（2.8%）的感染率要低得多。我们的分析支持在20世纪80年代将感染bfdv的爱鸟引入大凤凰地区，然后将其辐射到三个循环的不同谱系；apyv几乎没有表现出多样化。

期刊介绍： Launched in 1955, Virology is a broad and inclusive journal that welcomes submissions on all aspects of virology including plant, animal, microbial and human viruses. The journal publishes basic research as well as pre-clinical and clinical studies of vaccines, anti-viral drugs and their development, anti-viral therapies, and computational studies of virus infections. Any submission that is of broad interest to the community of virologists/vaccinologists and reporting scientifically accurate and valuable research will be considered for publication, including negative findings and multidisciplinary work.Virology is open to reviews, research manuscripts, short communication, registered reports as well as follow-up manuscripts.
