• HUMAN IMMUNODEFICIENCY VIRUS TYPE-1
• PERIPHERAL BLOOD MONONUCLEAR CELLS
• CD4+ T-CELLS
• HIV-1 DNA
• POLYMERASE CHAIN REACTION

This article describes a novel approach to quantitative polymerase chain reactions (PCR). The technique is simple to execute, can be performed in a single tube, and is suitable for automation. In addition, the counting and lysis of low numbers of cells (1-100) can be confirmed by phase contrast microscopy. In this study, the technique was used to determine the frequency of occurrence of DNA from the human immunodeficiency virus (type 1) in leukocyte subsets of peripheral blood mononuclear cells (PBMC) from sero-positive individuals. It was confirmed that the frequency of infected CD4+ T cells varied from 0.01 to 0.0001. In addition, HIV-1 DNA was detected in the B cell/dendritic cell-enriched subpopulation in four of nine HIV-1-positive individuals in the study.
