Abstract

The etiologic agent of the acquired immunodeficiency syndrome is a retrovirus included in the subclass of lentiviruses in view of certain characteristics common to these viruses. Their similarity is mainly represented by the extreme slowness of disease manifestation and by the fact that HIV, like other lentiviruses, spreads within the organism in spite of an immune reaction. The mechanism of replication is not dissimilar to that of other retroviruses except for the expression of a particularly large number of regulating genes the most important of which are called tat, rev, and nef. Further genes with a probable regulating function are nef, vpr, and vpx. In the field of diagnostic virology, together with normal isolation tests, a technique that has become particularly important is PCR (polymerase chain reaction) which allows to obtain a relevant amount of specific viral DNA sequences by the use of a DNA polymerase and specific primers.
