Two newborn marmosets, inoculated with a cell-free extract of feline fibrosarcomas, developed multiple sarcomas and died within 46 days of inoculation, whereas two of these animals inoculated with a crude homogenate developed no tumors. This susceptibility to a mammalian RNA sarcoma virus suggests that marmosets may be particularly suitable for attempts to isolate infectious agents from man.
