Identification of New HIV-1 Circulating Recombinant Forms CRF81_cpx and CRF99_BF1 in Central Western Brazil and of Unique BF1 Recombinant Forms [PDF]

Frontiers in Microbiology, 2019
Intersubtype recombinants classified as circulating recombinant forms (CRFs) or unique recombinant forms (URFs) have been shown to play an important role in the complex and dynamic Brazilian HIV/AIDS epidemic.

Identification of Two New HIV-1 Circulating Recombinant Forms (CRF87_cpx and CRF88_BC) from Reported Unique Recombinant Forms in Asia. [PDF]

AIDS Res Hum Retroviruses, 2017
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 ...

Near full genome characterization of HIV-1 unique recombinant forms in Cameroon reveals dominant CRF02_AG and F2 recombination patterns. [PDF]

J Int AIDS Soc, 2019
AbstractIntroductionIn Cameroon, a manifold diversity of HIV strains exists with CRF02_AG and unique recombinant forms (URFs) being the predominant strains. In recent years, a steady increase in URFs and clade F2 viruses has been monitored through partial genome sequencing.

Unassigned Complex Unique Recombinant Forms Related to CRF36_cpx in Children Identified in an HIV-1 Outbreak in Pakistan. [PDF]

AIDS Res Hum Retroviruses, 2022
In 2019, an outbreak of HIV infection predominantly affecting children occurred in Larkana district, Pakistan. This is the largest outbreak ever reported in this age group in Pakistan. In this study, we report two HIV-1 unique recombinant forms identified during the outbreak.

Recombination form and epidemiology of HIV-1 unique recombinant strains identified in Yunnan, China. [PDF]

PLoS ONE, 2012
Several studies identified HIV-1 recombination in some distinct areas in Yunnan, China. However, no comprehensive studies had been fulfilled in the whole province up to now.

Genome Sequence of Complex HIV-1 Unique Recombinant Forms Sharing a Common Recombination Breakpoint Identified in Malaysia. [PDF]

Genome Announc, 2015
ABSTRACT Three strains of HIV-1 unique recombinant forms (URFs) descended from subtypes B, B′, and CRF01_AE were identified among people who inject drugs in Kuala Lumpur, Malaysia. These three URFs shared a common recombination breakpoint in the reverse transcriptase region, indicating frequent linkage within the drug-injecting networks in ...

P20-05. Emergence of HIV-1 circulatory recombinant forms (CRFs) and unique recombinant forms (URFs) in North India: functional and pathogenic implications [PDF]

Retrovirology, 2009
Background After documentation of first case of HIV/AIDS in commercial sex worker in 1986 in India, it has now spread to all the states over a period of 22 years and become a major public health problem in India. Sex trafficking and injecting drug users are the main source for driving HIV-1 epidemic here.

Identification and characterization of two human immunodeficiency virus type 1 unique recombinant forms from Yunnan, China. [PDF]

Virol Sin, 2016
Recombination contributes greatly to the diversity of human immunodeficiency virus type 1 (HIV-1). A large number of recombinant strains have been found in China, particularly in Yunnan, which is considered the HIV-1 epicenter of China. Surveillance of unique recombinant forms is helpful for prediction of new circulating recombinant forms.

Characterization of two novel HIV-1 second-generation recombinants (CRF01_AE/CRF07_BC) identified in Hebei Province, China

Frontiers in Microbiology, 2023
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 ...

Molecular Epidemiology and Evolutionary Trajectory of Emerging Echovirus 30, Europe

Emerging Infectious Diseases, 2021
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.
