Real-Time PCR Assay for HIV-1 Subtype Diagnosis and Global Surveillance of Drug Resistance


CDC researchers have developed a patented set of RT-PCR and sequencing primers based on HIV-1 group M sequences. Evaluation of the primers using samples collected around the world demonstrated broad detection capacity for multiple HIV-1 group subtypes and predominant circulating recombinant forms. Commercially available HIV-1 drug resistance (HIVDR) genotyping assays are expensive and have limited ability to detect non-B subtypes. This optimized assay is broadly sensitive in genotyping HIV-1 group M viral strains and more sensitive than other assays in detecting mixed viral populations. This technology can be used in resource-limited settings where HIVDR surveillance is recommended to minimize the development and transmission of HIVDR.

  • Utility for HIV-1 sub-typing detection, evaluation of anti-HIV therapeutic efficacy, and HIV drug resistance (HIVDR) surveillance and monitoring
  • Rapid, accurate, and cost-effective technology easily adapted as a kit


Potential Commercial Applications: Competitive Advantages:
  • HIV-1 sub-typing diagnostic
  • Evaluation of efficacy of anti-HIV therapeutics
  • HIV drug resistance (HIVDR) surveillance and monitoring
 
  • Cost-effective
  • Simple to implement
  • Rapid, accurate and objectively conclusive
  • Easily implemented as a kit
  • Assay could be applicable to HIVDR genotyping in both ART-naive and ART-experienced populations
