Genomic characterization of a novel HIV type 1 B/G intersubtype recombinant strain from an injecting drug user in Germany.
Recombinant forms of HIV-1 contribute significantly to the ongoing epidemic. In the present study we characterize the full-length genome of a novel B/G intersubtype recombinant strain from a patient with a history of injection drug use. This is the first evidence of a B/G recombinant among injecting drug users in Germany. Moreover, this genetically divergent strain has important clinical implications since it was undetectable in the NucliSens HIV-1 QT assay and significantly underquantified by the COBAS MONITOR version 1.5 test relative to the LCx HIV RNA Quantitative assay. Phylogenetic analysis revealed that this recombinant virus is ancestrally related to CRF14_BG, but carries two additional subtype B-derived segments within vif and pol integrase.
