HIV-1 Circulating Recombinant Forms (CRFs) and Unique Recombinant Forms (URFs) in Israel, 2010–2018 [PDF]

Viruses, 2022
Monitoring HIV-1 circulating recombinant forms (CRFs) and unique recombinant forms (URFs) is important for disease surveillance. Recombination may affect prevention efforts and interfere with the diagnosis and treatment of HIV-1 infection.

Characterization of HIV-1 CRF02_AG/A3/G unique recombinant forms identified among children in Larkana, Pakistan [PDF]

Frontiers in Cellular and Infection Microbiology, 2023
Co-circulation of different human immunodeficiency virus type 1 HIV-1 subtypes among infected populations can lead to the generation of new recombinants. In Pakistan, subtype A1 and CRF02_AG are the dominant strains circulating among key populations. The

Recent increased identification and transmission of HIV-1 unique recombinant forms in Sweden [PDF]

Scientific Reports, 2017
A temporal increase in non-B subtypes has earlier been described in Sweden by us and we hypothesized that this increased viral heterogeneity may become a hotspot for the development of more complex and unique recombinant forms (URFs) if the epidemics ...

Genetic diversity of HIV in Yunnan, China: the role of second-generation recombination involving circulating and unique recombinant forms [PDF]

Virology Journal
Background The genetic diversity of HIV is significantly influenced by second-generation recombination events involving circulating recombinant forms (CRFs) and unique recombinant forms (URFs), which are crucial for the virus’s evolution and ...

Molecular characterization of a unique Recombinant form of HIV-1 subtype F2/CRF02_AG identified in Guangdong, China [PDF]

Virology Journal
Background The human immunodeficiency virus type 1 (HIV-1) pandemic continues to pose a significant global public health challenge. Recombination between HIV-1 variants generates unique recombinant forms (URFs) and then circulating recombinant forms ...

Identification of two near-identical novel HIV-1 unique recombinant forms (CRF01_AE/B) among men who have sex with men in baoding, hebei, China [PDF]

Frontiers in Genetics, 2023
Men who have sex with men (MSM) are the most frequent infection route of the human immunodeficiency virus (HIV) in Baoding, China, creating chances for the occurrence of unique recombinant forms (URFs) of the virus, i.e., recombination of different ...

HIV-1 subtypes B and C unique recombinant forms (URFs) and transmitted drug resistance identified in the Western Cape Province, South Africa. [PDF]

PLoS ONE, 2014
South Africa has the largest worldwide HIV/AIDS population with 5.6 million people infected and at least 2 million people on antiretroviral therapy. The majority of these infections are caused by HIV-1 subtype C. Using genotyping methods we characterized
