摘要:
Provided herein are new methods, primers, and kits for genotyping HIV-1, including group M viral strains. The methods can be used for HIV-1 drug resistance surveillance and monitoring, for example in resource-poor countries. The disclosed methods can detected more mixed HIV-1 population than previous methods. Given the high efficiency in genotyping diverse HIV-1 group M viral strains from plasma and dried blood spot (DBS) samples and substantial reagent cost saving, the disclosed methods can be used for HIV-1 drug resistance genotyping in both antiretroviral therapy (ART)-naive and -experienced populations for surveillance purposes and patient monitoring.
摘要:
Reagents and assays for detecting HIV-1 groups M and O and optionally HIV-1 group N and SIVcpz are provided. The reagents are nucleic acid primers for the hybridization to, amplification and subsequent detection of HIV-1 groups M, N and O and SIVcpz in a biological sample. The primers are oligonucleotides that selectively hybridize to the highly conserved regions of the env and pol regions of HIV-1. Due to the high sensitivity of the assays, small concentrations of HIV in a biological sample can be detected, allowing diagnosis at an early stage of infection. The assays are qualitative or quantitative and are useful for viral load determinations of HIV-1 groups M, N or O in a patient undergoing treatment for HIV-1 infection. Viral load determinations can be used to monitor the progress of the treatment regimen, the development of drug resistance, and to predict disease progression.

Due to the high sensitivity of the assays, small concentrations of HIV in a biological sample can be detected, thereby allowing diagnosis at an early stage of infection. The assays are also useful for detecting HIV-1 contamination in a biological fluid such as blood. The assays are qualitative or quantitative and are therefore useful for viral load determinations of HIV-1 groups M, N or O in a patient undergoing treatment for HIV-1 infection. Viral load determinations can be used to monitor the progress of the treatment regimen or the development of drug resistance and can be used to predict disease progression.
