Virol·,1991,117 : 129_ 135]。然而最近的研究卻顯示出更複雜之轉譯作用[米漢 (Meehan) Β·Μ·等人,j· Gen. Virol·,1997,78 : 221-227]。此 外,此三種已知環狀病毒之核芬酸序列或一般抗原決定位 並無明顯已知的同源性。 分離自PK/15細胞之PC V被認定爲非病原性。其序列係得 知於 B.M.米漢等人,j. Gen. Virol.,1997,(78) : 221-227。 最近某些人認爲PCV病毒株可爲病原性且與PMWS症候群有 關[G.P.S.那亞(Nayar)等人,Can. Vet· J·,1997,38 : 385-387 及克拉克(Clark) E.G.,Proc. Am. Assoc.
