Recent DNA sequence analysis indicates that rhesus rhadinovirus (RRV) is a
member of the lymphotropic gamma-2 herpesvirus family. To determine if RRV
is lymphotropic, peripheral blood mononuclear cells from naturally infected
monkeys were separated by immunomagnetic bead depletion and analyzed for t
he presence of RRV by virus isolation and nested PCR The recovery and consi
stent detection of RRV in the CD20(+)-enriched fraction clearly demonstrate
s that B lymphocytes are a major site of virus persistence.
