Recombination analysis and structure prediction show correlation between breakpoint clusters and RNA hairpins in the pol gene of human immunodeficiency virus type 1 unique recombinant forms [PDF]

Journal of General Virology, 2008
Recombination is recognized as a primary force in human immunodeficiency virus type 1 (HIV-1) evolution, increasing viral diversity through reshuffling of genomic portions.

Current HIV type 1 molecular epidemiology profile and identification of unique recombinant forms in Jakarta, Indonesia. [PDF]

AIDS Res Hum Retroviruses, 2009
HIV infection is a major problem in Indonesia. The number of people living with HIV has been increasing from year to year, especially among injecting drug users (IDUs). Since there were only limited data about molecular epidemiology profiles of HIV/AIDS in Indonesia, a cross-sectional study involving 208 HIV-1-seropositive individuals was conducted in ...

Novel HIV-1 Recombinant Forms in Antenatal Cohort, Montreal, Quebec, Canada

Emerging Infectious Diseases, 2011
Near full-length genomes of 4 unclassified HIV-1 variants infecting patients enrolled in an antenatal cohort in Canada were obtained by sequencing. All 4 variants showed original recombination profiles, including A1/A2/J, A1/D, and A1/G/J/CRF11_cpx ...

Characterization of New Recombinant Forms of HIV-1 From the Comunitat Valenciana (Spain) by Phylogenetic Incongruence [PDF]

Frontiers in Microbiology, 2019
Recombination is one of the main processes shaping the evolution of HIV-1, with relevant consequences for its epidemiology. In fact, Circulating and Unique Recombinant Forms (CRFs and URFs) cause 23% of current infections.

THE PREVALENCE OF HIV RECOMBINANT FORMS IN RUSSIA AND COUNTRIES OF THE CIS: SYSTEMATIC REVIEW AND METAANALYSIS

Инфекция и иммунитет, 2018
This review was to aimed to access the prevalence of HIV recombinant forms in Russia and countries of the CIS, which have  close social and economic ties. We conducted a search in Russian  Science Citation Index and PubMed for a depth of 8 years.

Characterization of a novel HIV-1 unique recombinant form between CRF07_BC and CRF55_01B in men who have sex with men in Guangzhou, China.

PLoS ONE, 2017
Here, we report the genetic diversity of HIV-1 and emergence of novel HIV-1 unique recombinant forms (URF) in both HIV-infected intravenous drug users (IDU) and men who have sex with men (MSM) in Guangzhou, China.

Identification and genomic characterization of a novel HIV-1 unique recombinant form (CRF01_AE/CRF07_BC) in Zhejiang Province, China [PDF]

Virus Genes, 2022
AbstractMutation and recombination are important mechanisms leading to the frequent evolution and genetic diversity of viruses as HIV-1. In this study, we identified the near full-length genomic characterization of a novel HIV-1 unique recombinant form (URF) strain (Sample ID: ZJ20202195/ZJ/CHN/2020, hereafter referred to as ZJ20202195) isolated during

HIV-1 Genetic Diversity and Transmitted Resistance to Integrase Strand Transfer Inhibitors in Benguela, Angola [PDF]

Microorganisms
Angola is one of the countries with the highest HIV-1 genetic diversity, yet the implications of this diversity for antiretroviral therapy remain insufficiently characterised. Following the introduction of dolutegravir (DTG) in Angola in 2021, evaluating

Temporal trends in the Swedish HIV-1 epidemic: increase in non-B subtypes and recombinant forms over three decades. [PDF]

PLoS ONE, 2014
BACKGROUND: HIV-1 subtype B (HIV-1B) still dominates in resource-rich countries but increased migration contributes to changes in the global subtype distribution. Also, spread of non-B subtypes within such countries occurs.
