NEW YORK, May 2 - Applied Biosystems said Tuesday it had agreed to supply its ViroSeq HIV-1 Genotyping Kits to Brazil’s National Ministry of Health, which will use the system to study the effectiveness of conducting genotyping in the clinic.

The one-year study, which is being partially funded by the World Bank, will run 6,000 tests on HIV-positive patients who have previously failed to respond to a drug regimen known as the Highly Active AntiRetroviral Therapy.
