In the US, sampling for avian paramyxovirus serotype-1 (APMV-1) is generally conducted when morbidity or mortality events occur involving certain families of wild birds known to be affected by the virus, such as cormorants (Family Phalacrocoracidae), pigeons, doves (Family Columbidae), or pelicans (Family Pelecanidae). To quantify the prevalence of APMV-1 in apparently healthy wild birds and to determine its geographic distribution, we collected swab and serum samples from >3,500 wild birds, representing eight orders from 1 January 2013 to 30 September 2013. Antibody prevalence was highest in wild birds of Order Suliformes (44.9%), followed by Pelecaniformes (24.4%), Anseriformes (22.7%), and Columbiformes (11.7%), with a relatively high occurrence of virulent viruses in Columbiformes (100% of virulent viruses isolated). As expected, viral shedding was comparatively much lower, and positives were only identified in Orders Accipitriformes (1.4%), Columbiformes (1.0%), Anseriformes (0.8%), and Charadriiformes (0.4%). We also demonstrate circulating virulent APMV-1 viruses of genotype VI in apparently healthy Rock Pigeons ( Columba livia ) from March through September in three states.
在美国，当涉及某些已知受禽副粘病毒1型（APMV-1）影响的野生鸟类家族（如鸬鹚科、鸽子、鸠鸽科或鹈鹕科）出现发病或死亡事件时，通常会进行APMV-1采样。为了量化APMV-1在看似健康的野生鸟类中的流行率并确定其地理分布，我们在2013年1月1日至2013年9月30日期间，从代表八个目、超过3500只野生鸟类中采集了拭子和血清样本。抗体流行率在鲣鸟目野生鸟类中最高（44.9%），其次是鹈形目（24.4%）、雁形目（22.7%）和鸽形目（11.7%），鸽形目中强毒株的出现率相对较高（分离出的强毒株占100%）。正如预期的那样，病毒排泄率相对低得多，仅在鹰形目（1.4%）、鸽形目（1.0%）、雁形目（0.8%）和鸻形目（0.4%）中检测到阳性。我们还证明，在三个州，从3月到9月，看似健康的原鸽（Columba livia）体内存在基因型VI的APMV-1强毒株在传播。
