title: Type-C RNA viruses of the NIH nude mouse.
abstract: Several types of tumors from various species were propagated in NIH athymic nude mice. Subsequently, cell lines were established from the tumors and examined for evidence of type-C virus activity. Hybrid mice (NIH Swiss and BALB/c) harbored murine type-C viruses of three categories: N-tropic, B-tropic and X-tropic.
