Identification and Characterization of Two New HIV Type 1 Unique (B/C) Recombinant Forms in China

AIDS Research and Human Retroviruses, 2011
Recombination was most important in the generation of new viral strains and in the increase of HIV diversity. There were more and more new HIV-1 strains. Not only circulating recombinant forms (CRFs) but also unique recombinant forms (URFs) have been reported around the world.

Identification of Three HIV-1 Unique (B/C) Recombinant Forms in Shaanxi, China

AIDS Research and Human Retroviruses, 2019
HIV-1 intersubtype B/C recombinants were more commonplace reported in high-risk populations in Yunnan province, China. In this study, three unique (B/C) recombinant isolates (2015YL02, 2018YL07, and SN18015) were identified from patients infected with HIV-1 through sexual transmission in Shaanxi province.

High Prevalence of Unique Recombinant Forms of HIV-1 in Ghana: Molecular Epidemiology From an Antiretroviral Resistance Study

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2008
In Ghana, programs to expand antiretroviral access are being implemented. In this context, the dynamic genetic evolution of HIV-1 requires continuous surveillance, particularly when diverse genetic forms co-circulate.Phylogenetic and antiretroviral resistance analyses of HIV-1 partial pol sequences from plasma RNA samples from 207 Ghanaian individuals ...

Sequence Notes: Characterization of Two Novel HIV-1 Unique Recombinant Forms (CRF01_AE/B) in Hebei Province

AIDS Research and Human Retroviruses
Many new circulating recombinant forms (CRFs) and unique recombinant forms (URFs) of human immunodeficiency virus type-1 (HIV-1) have been discovered in populations with multiple circulating HIV-1 genotypes. In this study, we report two novel URFs derived from two individuals who were HIV-1 positive in Hebei, China, who were infected through homosexual

Genetic characterization of a novel unique recombinant form of HIV-1 originating from subtype A1 and C in Guangdong Province, China

Archives of Virology, 2018
The dominant human immunodeficiency virus type 1 (HIV-1) subtypes are CRF01_AE, CRF07_BC and CRF08_BC in Guangdong Province, China. In this study, we report a unique recombinant form (URF) of HIV-1 that was identified in an HIV/hepatitis B virus (HBV)/hepatitis C virus (HCV) triple-infected patient who was an intravenous drug user (IDU) in Heyuan City,
