Nucleotide Sequence of Porcine Circovirus Associated with Postweaning Multisystemic Wasting Syndrome in Pigs

This article describes the nucleotide sequence of a porcine circovirus (PCV) which possesses a high degree of association with postweaning multisystemic wasting syndrome (PMWS), a newly described disease of young pigs. The DNA sequence of this PMWS-associated PCV (pmws PCV) has 68% homology with that of a previously published nonpathogenic strain of PCV. The strains appear to be closely related yet distinct from one another.

本文报道了一株与断奶后多系统衰弱综合征（postweaning multisystemic wasting syndrome, PMWS）高度相关的猪圆环病毒（porcine circovirus, PCV）的核苷酸序列，该综合征是一种新近被描述的仔猪疾病。该与PMWS相关的PCV（pmws PCV）的DNA序列，与此前已发表的一株非致病性PCV毒株的DNA序列具有68%的同源性。两类毒株看似亲缘关系密切，但彼此间又存在显著差异。
