Identification of Two Similar Novel HIV-1 Recombinant Forms (CRF01_AE/CRF07_BC) among Intravenous Drug Users in Guangxi, China.
New kinds of HIV-1 circulating recombinant forms (CRFs) and unique recombinant forms (URFs) earn a great prevalence in China nowadays. In this study, we identified 2 similar URFs (2016GXNNIDU037 and 2019QZLSIDU253) both isolated from intravenous drug users (IDUs) in Guangxi, China. Phylogenetic analysis of the near full-length genome (NFLG) revealed 2 URFs both clustered with CRF01_AE but setting up a monophyletic branch, supporting a high bootstrap value. Bootscan analysis and subregional recombinant analysis found that the NFLG of 2016GXNNIDU037 and 2019QZLSIDU253 were both composed of CRF01_AE and CRF07_BC, with 3 CRF07_BC mosaic segments inserted into CRF01_AE backbones. The CRF01_AE segments of the 2 URFs clustered with a previously reported cluster 2 lineage of CRF01_AE. The 5 recombinant breakpoints of the 2 URFs were quite similar. Distinct from CRF01_AE/CRF07_BC URFs reported before, 2016GXNNIDU037 and 2019QZLSIDU253 are new evidence of a high genetic variety of HIV-1 in Guangxi, which may pose new challenges to HIV-1 prevention and molecular epidemiological surveillance in China.
期刊介绍：
''Intervirology'' covers progress in both basic and clinical virus research, and aims to provide a forum for the various disciplines within virology. Issues publishing original papers alternate with thematic issues, focusing on clearly defined topics. This thematic concentration serves to make timely reviews, research reports and controversy easily accessible to both specialists in the field and those who want to keep track of the latest developments outside their own area of interest. In addition to original papers, regular issues publish short communications and letters to the editor to provide readers with a forum for the exchange of ideas and comments. The scope encompasses work on the molecular biology of human and animal viruses, including genome organization and regulation, and the structure and function of viral proteins. The pathogenesis, immunology, diagnosis, epidemiology, prophylaxis and therapy of viral diseases are considered.
