Abstract

Infectious bovine rhlnotracheitis virus [IBRV- (HMC)], a double-enveloped herpesvirus, was Isolated from human embryo lung fibroblasts transformed by cytomegalovirus (CMV). This agent was identified as an IBRV strain that was antigenically related to human CMV. Inoculation of a primary human kidney cancer cell culture with IBRV(HMC) resulted In persistent Infection and subsequent establishment of a cell line [IBRV(HMC)HKC-1]. Virus-related nuclear, cytoplasmic, and cell membrane antigens were detected in these cells in early in vitro passages by anticomplement and Indirect Immunofluorescence tests. Infectious virus was rescued from one of the cell sublines after temperature-shock treatment at passage 26. Karyotypic analysis confirmed the human origin of the cells. Control uninfected kidney cancer cells survived only six in vitro passages. The established cells grew to more than 100 in vitro passages 1 year after Initiation of the experiments and induced an epithelioid cancer of variable morphology that Infiltrated nerves and muscles when Inoculated sc Into athymlc nude mice.
