No common antigenic determinants and no DNA sequence homologies were detected when three animal viruses, chicken anaemia agent (CAA), porcine circovirus (PCV), and psittacine beak and feather disease virus (PBFDV), all of which possess circular single-stranded DNA genomes, were compared. Negative contrast electron microscopy showed that PCV and PBFDV particles were 30% smaller than CAA particles and lacked the surface structure of CAA.
当对三种动物病毒进行比较时，未检测到共同的抗原决定簇和DNA序列同源性。这三种病毒分别是鸡贫血因子（CAA）、猪圆环病毒（PCV）和鹦鹉喙羽病病毒（PBFDV），它们均具有环状单链DNA基因组。负染电子显微镜观察显示，PCV和PBFDV病毒颗粒比CAA病毒颗粒小30%，且缺乏CAA的表面结构。
