HIV-2 in rhesus monkeys: serological, virological and clinical results.

abstract：:There are two major requirements for potyvirus taxonomy; group-specific criteria and criteria which discriminate between distinct viruses and strains. This review discusses the relative merits in potyvirus taxonomy of molecular parameters, such as gene sequence data, nucleic acid hybridization, coat protein sequence d...
