Detection and serotyping of herpes simplex virus in MRC-5 cells by use of centrifugation and monoclonal antibodies 16 h postinoculation.
Monoclonal antibodies (Syva Co., Palo Alto, Calif.) were used for the detection and serotyping of herpes simplex virus (HSV) isolates by immunofluorescence 16 h after inoculation of MRC-5 monolayers in 3.7-ml shell vials and after low-speed centrifugation. A total of 119 specimens were inoculated into conventional tube cell cultures and shell vials. Of 98 specimens inoculated on the same day of receipt in the laboratory (fresh specimens), all 23 (23.5%) HSV-positive specimens were identified by serotype in 16 h in shell vials by immunofluorescence, whereas only 8 of 23 HSV-positive specimens (34.8%) produced cytopathic effects in conventional tube cell cultures in this time period. Similarly, of 21 original specimen extracts previously determined to be culture positive for HSV (stored specimens), all were detected and serotyped by the immunofluorescence test with monoclonal antibodies 16 h postinoculation compared with the recognition of only 8 of these isolates (38.1%) by cytopathic effect that soon. This technique of centrifugal inoculation of HSV in shell vials containing MRC-5 cells permitted detection of this virus in all positive specimens with serotype determination within 16 h postinoculation.
