Identification of CRF89_BF, a new member of an HIV-1 circulating BF intersubtype recombinant form family widely spread in South America

open access: yesScientific Reports, 2021
Circulating recombinant forms (CRFs) contribute substantially to the HIV-1 pandemic. Among 105 CRFs described in the literature, 16 are BF intersubtype recombinants, most of South American origin, of which CRF12_BF is the most widely spread.

Mathematical Model of HIV-1 Circulating Recombinants Forms in Mali

open access: yesOpen Journal of Modelling and Simulation, 2015
In this paper, we propose a determinist mathematical model for the co-circulating into two circulating recombinants forms (CRFs) Of HIV-disease in Mali. We divide the sexually active population within three compartments (susceptible, CRF-1 infected and CRF-2 or CRF-12 infected) and study the dynamical behavior of this model.

Characterization of a novel HIV-1 circulating recombinant form, CRF91_cpx, comprising CRF02_AG, G, J, and U, mostly among men who have sex with men

open access: yesVirulence, 2022
Prospective molecular studies of HIV-1 pol region (2253–5250 in HXB2 genome) sequences from sequenced samples of 269 HIV-1-infected patients in Cyprus (2017–2021) revealed a transmission cluster of 14 unknown HIV-1 recombinants that were not classified ...

Circulating Coxsackievirus A16 Identified as Recombinant Type A Human Enterovirus, China

open access: yesEmerging Infectious Diseases, 2011
To determine the relationship of coxsackievirus A16 (CA16) to prototype CA16-G10, we conducted a phylogenetic analysis of circulating CA16 strains in China.

In Vitro Intersubtype Recombinants of Human Immunodeficiency Virus Type 1: Comparison to Recent and Circulating In Vivo Recombinant Forms [PDF]

open access: yesJournal of Virology, 2002
ABSTRACT The increased prevalence of human immunodeficiency virus type 1 (HIV-1) intersubtype recombinants (ISRs) is shaping HIV-1 evolution throughout the world and will have an impact on both therapeutic and vaccine strategies.

Recombination Pattern Reanalysis of Some HIV-1 Circulating Recombination Forms Suggest the Necessity and Difficulty of Revision

open access: yesPLoS ONE, 2014
Recombination is one of the major mechanisms underlying the generation of HIV-1 variability. Currently 61 circulating recombinant forms of HIV-1 have been identified. With the development of recombination detection techniques and accumulation of HIV-1 reference stains, more accurate mosaic structures of circulating recombinant forms (CRFs), like CRF04 ...

Spatiotemporal and demographic history of the HIV-1 circulating recombinant form CRF31_BC in Brazil

open access: yesInfection, Genetics and Evolution, 2018
CRF31_BC is an HIVs-1 recombinant form very prevalent in the southernmost capital city of Brazil, Porto Alegre. Recent studies have been describing a growing number of cases of infection by CRF31_BC in other Brazilian cities and countries, suggesting a process of expansion of this strain.

Recombination Confounds the Early Evolutionary History of Human Immunodeficiency Virus Type 1: Subtype G Is a Circulating Recombinant Form [PDF]

open access: yesJournal of Virology, 2007
ABSTRACT Human immunodeficiency virus type 1 (HIV-1) is classified in nine subtypes (A to D, F, G, H, J, and K), a number of subsubtypes, and several circulating recombinant forms (CRFs). Due to the high level of genetic diversity within HIV-1 and to its worldwide distribution, this classification system is widely used in fields as ...
