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

AIDS Research and Human 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.

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.

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

Journal of the International AIDS Society, 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.

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

Genome Announcements, 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 ...

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

Virologica Sinica, 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.

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.

Viruses Previously Classified as CRF146_BC, a Circulating Recombinant Form of HIV-1 Recently Reported in Brazil, Represent Different Recombinant Forms, One of Which Is Circulating in Spain [PDF]

Viruses
Circulating recombinant forms (CRFs) are important components of the HIV-1 pandemic. Previous studies have reported the propagation of diverse HIV-1 CRFs of South American origin in Europe.

Emergence of HIV-1 unique DG recombinant form in Pakistan

AIDS Research and Human Retroviruses, 2019
After the first case of HIV infection in 1987, the number of cases has continuously increased in Pakistan, turning from isolated incidents to outbreaks to the concentrated epidemic. The HIV epidemic in Pakistan is mainly driven by subtype A, however, the
