Lentivirus
Lentivirus represents a genus of slow viruses with long incubation period (months, even years) and a propensity to induce a wide range of pathologies in different animal species. Due to their rather flexible genome and a potential of transducing many forms of nondividing cells, lentiviruses have become one of the most widely used vectors for gene transfer.
