Porcine circovirus (PCV) genomes are single-stranded circular DNAs of about 1770 nucleotides (nt). Here, we present for the first time two small PCV-like agents with circular DNA genomes (258 and 264 nt) in pigs and two (201 and 347 nt) in cattle, with no obvious protein-coding capacity. Sequences of the four PCV-like mini agents differed by 1.5%–18.7% from each other and by 4.5%–56.7% from other reference PCV strains and PCV-like viruses.
