Porcine circovirus type 2 (PCV-2) has been associated with syndromes grouped by the term porcine circovirus associated diseases (PCVAD). The PCV-2 isolates have been grouped into two major groups or genotypes according to their nucleotide sequence of whole genomes and/or ORF-2: PCV-2b, which have, in turn, been subdivided into three clusters (1A-1C), and PCV-2a, which has been subdivided into five clusters (2A-2E). In the present study, we obtained 16 sequences of PCV-2 from different farms from 2003 to 2008, from animals with confirmatory diagnosis of PCVAD. Since results showed an identity of 99.8% among them, they were grouped within a common cluster 1A-B. This preliminary study suggests a stable circulation of PCV-2b among the Argentinean pig population.
猪圆环病毒2型（PCV - 2）与统称为猪圆环病毒相关疾病（PCVAD）的一系列综合征有关。根据全基因组和/或ORF - 2的核苷酸序列，PCV - 2分离株已被分为两个主要组或基因型：PCV - 2b，又可细分为三个簇（1A - 1C），以及PCV - 2a，可细分为五个簇（2A - 2E）。在本研究中，我们从2003年至2008年期间不同猪场确诊患有PCVAD的动物中获得了16个PCV - 2序列。由于结果显示它们之间的同一性为99.8%，因此它们被归为一个共同的1A - B簇。这项初步研究表明PCV - 2b在阿根廷猪群中稳定传播。
