Field evaluation of a gag/env heteroduplex mobility assay for genetic subtyping of small-ruminant lentiviruses.
Small-ruminant lentiviruses (SRLVs) display a high genetic diversity and are currently classified into five genotypes and an increasing number of subtypes. The co-circulation of subtypes in restricted geographical regions, combined with the occurrence of cross-species infection, suggests the need for development of a large-scale screening methodology for rapid monitoring of the prevalence of th...
متن کاملDevelopment of an env gp41-based heteroduplex mobility assay for rapid human immunodeficiency virus type 1 subtyping.
The gp120 region of the human immunodeficiency virus type 1 (HIV-1) envelope (env) gene exhibits a high level of genetic heterogeneity across the group M subtypes. The heteroduplex mobility assay (HMA) has successfully been used to assign subtype classifications, but C2V5 primers often fail to amplify African strains. We developed an env gp41-based HMA for which the target sequence is amplified...
متن کاملRapid detection of HIV-1 subtypes in Ghana by heteroduplex mobility assay
Background: In Ghana, the HIV-1 profile has been quite dynamic. Previous reports identified HIV-1 subtypes A, D and G present and recently the CRF02_AG has been described as the predominant molecular form of HIV-1 in Kumasi, Ghana. This underscores the need for constant molecular characterization of HIV-1 species in the country. Objective: To provide current updates on the nature of HIV subtype...
متن کاملHIV-1 subtyping using phylogenetic analysis of pol gene sequences.
HIV-1 pol gene sequencing is now used routinely in France to identify mutations associated with resistance to reverse transcriptase (RT) or protease (PR) inhibitors. These sequences may also provide other information, such as the HIV-1 subtype. HIV-1 subtyping was compared using the RT and PR gene sequences to heteroduplex mobility assay (HMA) of the envelope gene. The RT and PR genes of 51 sam...
متن کاملIdentification and recovery of minor HIV-1 variants using the heteroduplex tracking assay and biotinylated probes
We describe a method to identify and recover minor human immunodeficiency virus type 1 (HIV-1) sequence variants from a complex population. The original heteroduplex tracking assay (HTA) was modified by incorporating a biotin tag into the probe to allow for direct sequence determination of the query strand. We used this approach to recover sequences from minor HIV-1 variants in the V3 region of...
