title: [Feline leukemogenic and sarcomatogenic viruses].
abstract: Feline Leukemia and sarcoma viruses (FeLV, FeSV) are RNA viruses, belonging to the Oncornavirus group. They possess common morphological, biochemical and immunological properties, with viruses of leukemia and sarcoma already known in others mammalian and avian species. FeLV is widely present in feline population and its transmission is by horizontal way. FeLV and FeSV are oncogenic for others species, i.e., dog and some non-human primates but as far as we know, the human receptivity is not established. A correlation between humoral antibody directed against membran new-antigens and regression of tumors induced by FeSV, led to actual investigations on vaccination.
