In vivo safety assessment of two Bifidobacterium longum strains.

abstract：:Measuring the amount of HIV-1 DNA in infected cells is important to estimate the size of the viral reservoir in patients. However, the clinical impact of the intracellular viral DNA level remains unclear. The present study examines the clinical significance of the HIV-1 DNA level in peripheral CD4+ T lymphocytes from ...
