Abstract

Cocirculation of subtype B and CRF01_AE in Southeast Asia has led to the establishment of new recombinant forms. In our previous study, we found five samples suspected of being recombinants between subtype B and CRF01_AE, and here, we analyzed near full-length sequences of two samples and compared them to known CRFs_01B, subtype B, and CRF01_AE. Five overlapped segments were amplified with nested PCR from PBMC DNA, sequenced, and analyzed for genome mosaicism. The two Indonesian samples, 07IDJKT189 and 07IDJKT194, showed genome-mosaic patterns similar to CRF33_01B references from Malaysia, with one short segment in the 3' end of the p31 integrase-coding region, which was rather more similar to subtype B than CRF01_AE, consisting of unclassified sequences. These results suggest gene-specific continuous diversification and spread of the CRF33_01B genomes in Southeast Asia.

摘要

B亚型和CRF01_AE亚型在东南亚的共同传播导致了新重组形式的出现。在我们之前的研究中,我们发现了5个疑似B亚型和CRF01_AE亚型之间重组体的样本,在此,我们分析了其中2个样本的近全长序列,并将它们与已知的CRFs_01B、B亚型和CRF01_AE进行比较。用巢式PCR从外周血单个核细胞(PBMC)DNA中扩增出5个重叠片段,进行测序,并分析基因组镶嵌性。两个印度尼西亚样本07IDJKT189和07IDJKT194显示出与来自马来西亚的CRF33_01B参考序列相似的基因组镶嵌模式,在p31整合酶编码区的3'端有一个短片段,该片段与B亚型的相似性高于CRF01_AE亚型,由未分类序列组成。这些结果表明CRF33_01B基因组在东南亚存在基因特异性的持续多样化和传播。
