Identification of Two New HIV-1 Circulating Recombinant Forms (CRF87_cpx and CRF88_BC) from Reported Unique Recombinant Forms in Asia [PDF]
The on-going generation of HIV-1 intersubtype recombination has led to new circulating recombinant forms (CRFs) and unique recombinant forms (URFs) in Asia. In this study, we evaluated whether previously reported URFs were actually CRFs. All available complete or near full-length HIV-1 URF sequences from Asia were retrieved from the HIV Los Alamos ...

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

Recombinant HIV-1 genomes identified in three or more epidemiological unrelated individuals are defined as circulating recombinant forms (CRFs). CRFs can further recombine with other pure subtypes or recombinants to produce secondary recombinants.

IntroductionThe unique recombinant forms (URFs) of HIV-1 consist of a mixture of subtypes, and each URF has a unique breakpoint. In this study, we identified the near fulllength genome (NFLG) sequences of two novel HIV-1 URFs (Sample ID: BDD034A and ...

HIV-1 Circulating Recombinant Form in Nepal [PDF]
In the year 2000, Oelrichs et al. reported the presence of HIV-1 subtype C in Nepal ([3][1]). These findings were based on the env gene sequences from 36 HIV-1 patients. They reported that Nepali HIV sequences showed a close clustering pattern with the Indian reference sequences, indicating ...

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

Molecular Epidemiology and Evolutionary Trajectory of Emerging Echovirus 30, Europe
In 2018, an upsurge in echovirus 30 (E30) infections was reported in Europe. We conducted a large-scale epidemiologic and evolutionary study of 1,329 E30 strains collected in 22 countries in Europe during 2016–2018.

Identification of an HIV-1 BG Intersubtype Recombinant Form (CRF73_BG), Partially Related to CRF14_BG, Which Is Circulating in Portugal and Spain. [PDF]
HIV-1 exhibits a characteristically high genetic diversity, with the M group, responsible for the pandemic, being classified into nine subtypes, 72 circulating recombinant forms (CRFs) and numerous unique recombinant forms (URFs).
