Analogie entre les rétrovirus humains lymphotropes et les rétrovirus des grands animaux.
The family Retroviridae comprises some fifty viruses in three subfamilies: Oncoviridae, Lentiviridae and Spumaviridae. A better understanding of retroviral pathobiology has resulted from the rapid developments in knowledge of the molecular biology of normal and cancerous cells as well as retroviruses. Genomic relatedness was found between two human T cell leukemia viruses and bovine leukemia virus; similarly, some relatedness appears possible between human AIDS (acquired immunodeficiency syndrome) virus and lentiviruses of large animals. Because of their genomic relatedness, retroviruses from man and animals could theoretically form recombinants during in vitro manipulation. Therefore persons who work with retroviral materials should follow established laboratory practices to control infectious agents.
