Altered pathogenicity of avian myelocytomatosis (MC29) viruses with mutations in the v-myc gene.

abstract：:Central African tropical forests are home to several species of non-human primates (NHPs), infected by Simian Immunodeficiency Virus (SIV). It is well-known that HIV-1 epidemic is due to cross-transmission and adaptation of SIV to humans. The main goal of this work was to investigate if a NHP bite is a risk factor for...
