Abstract: | Infection of a continuous cell line of dog kidney origin (MDCK) with herpes simplex virus type 2 (HSV-2) resulted in production of little to no new infectious virus. Serial subculture of MDCK cells inoculated with HSV-2 did not permit establishment of carrier cell cultures, as assessed by negative results of plaque assays for infectious virus and radioimmunoassay (RIA) for viral antigens. Group- and type-specific antigens were detected in lysates of non-permissive MDCK cells inoculated with HSV-2 and tested by RIA at 24 hours post-inoculation. Polypeptides produced in permissive (Vero) and non-permissive (MDCK) cell systems were labeled with 14C]-amino acids and analyzed by polyacrylamide slab gel electrophoresis and autoradiography. During non-permissive infection, two polypeptides of large molecular weight, not found in uninfected MDCK cells, one of which commigrated with a major HSV-2 structural polypeptide, were synthesized and reproducibly detected. |
