title: Effect of arginine deficiency on the reproduction of human cytomegalovirus.
abstract: In arginine-deprived human embryonic fibroblasts the reproduction cycle of human cytomegalovirus (CMV) is incomplete. Infectious virus cannot be demonstrated in cell disintergrates, and from among the CMV antigens only the diffuse cytoplasmic antigen is detectable by immunofluorescence. The antigens localized in the cell membrane and those appearing during the complete cycle as large granules or inclusion-like bodies in the nucleus do not appear in the absence of arginine. The CMV genome persists in the arginine-deprived culture; after re-feeding with arginine-containing medium, maturation of virions soon ensues. Maturation could be prevented by inhibitors of protein synthesis, but not by DNA inhibitors, added simultaneously with completion of the medium.
