HIV-2 CRF01_AB: First Circulating Recombinant Form of HIV-2

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2010
Five HIV-2-seropositive cases were recently identified in Japan, outside the HIV-2 endemic area of West Africa. To clarify the molecular epidemiology of HIV-2 in Japan, we analyzed sequences of these cases in detail.HIV-2 genetic groups were determined by gag and env sequences. For suspected recombinant isolates, the genetic structure was determined by

Circulating and Unique Recombinant Forms of HIV Type 1 Containing Subsubtype A2

AIDS Research and Human Retroviruses, 2006
HIV-1 strains containing subsubtype A2 are relatively rare in the pandemic but have been repeatedly identified in Kenya, where candidate vaccines based in part on subtype A, but not A2 strains, may be evaluated. Among the most recent is CRF16_A2D, a circulating recombinant form (CRF) whose prototypes are complete or partial HIV-1 sequences from Kenya ...

Identification of a Novel HIV-1 Circulating Recombinant Form (CRF85_BC) in Sichuan, China

AIDS Research and Human Retroviruses, 2016
We report a novel HIV circulating recombinant form (CRF B/C) identified from 10 epidemiologically unlinked individuals in Sichuan province, China, all self-report infected by heterosexual behavior. Sequencing and analyzing the near-full-length genome of these strains revealed this recombinant form to be composed of subtype B (China and Thailand) and ...

Characterization of an Invisible HIV-1 Circulating Recombinant Form (CRF149_01B) in China

AIDS Research and Human Retroviruses
In this study, by analyzing the available near full-length genome (NFLG) sequences of CRF55_01B, it was found that two of the NFLG sequences could not be clustered with other NFLG sequences. Recombination analysis and phylogenetic analysis suggested that these two NFLG sequences arose by recombination with subtype B based on CRF55_01B, rather than by ...

Identification of a new HIV Type 1 Circulating Recombinant Form (CRF38_BF1) in Uruguay

AIDS Research and Human Retroviruses, 2009
Recombination has been shown to be an important force in HIV-1 evolution. Recombination contributes to an increase in genetic variation and hinders vaccine design efforts. Several molecular epidemiology studies in South America described the circulation of subtypes B, F, and C as well as several B/F1 recombinants.

A New Human Immunodeficiency Virus Type 1 Circulating Recombinant Form from Tanzania

AIDS Research and Human Retroviruses, 2001
It is becoming increasingly important to identify and to study human immunodeficiency virus type 1 (HIV-1) circulating recombinant forms (CRFs) with evidence of epidemic spread, since mosaic strains arise frequently, especially in populations where multiple subtypes cocirculate.

Identification of New Circulating Recombinant Form of HIV-1 CRF127_07109 in Northern Vietnam

AIDS Research and Human Retroviruses
Some candidates of a new circulating recombinant form (CRF) of HIV-1 were found in northern Vietnam in our previous study. We succeeded in near full-length sequencing using MinION with plasma samples from 12 people living with HIV. Three of the samples were CRF109_0107, which was recently reported in China.

Identification of a Novel HIV-1 Circulating ADG Intersubtype Recombinant Form (CRF19_cpx) in Cuba

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2005
Circulating recombinant forms (CRFs) represent a substantial proportion of HIV-1 isolates in the global pandemic. Characterization of HIV-1 genetic forms, including CRFs, may be relevant to studies on molecular epidemiology, recombination, superinfection, vaccine development, and antiretroviral therapy.

Identification of a New HIV-1 Circulating Recombinant Form CRF65_cpx Strain in Jilin, China

AIDS Research and Human Retroviruses, 2018
This study reported a new HIV-1 circulating recombinant form CRF65_cpx virus isolated from a man who have sex with men (MSM) in Jilin, China. The near full-length genome of this virus was composed of 14 mosaic gene fragments derived from CRF01_AE, subtype B' (Thai B) and subtype C, highly similar to the CRF65_cpx viruses recently identified in Yunnan ...
