Isoenzymes of lactate dehydrogenase, acid phosphatase, alkaline phosphatase and peroxidase in monkey kidney cell cultures inoculated with herpes virus type 1.

The variation of lactate dehydrogenase, peroxidase, acid and alkaline phosphatase isoenzymes was studied in VERO cells inoculated with infectant and UV-inactivated herpes simplex virus type 1 (HSV--1). Infectant HSV--1 induced quantitative and qualitative modifications in isoenzyme patterns within the first 4 hours post inoculation (p.i.). The modifications caused by the UV-inactivated HSV--1 were similar, but appeared 8 hours p.i. The possibility of using isoenzyme modifications as rapid, sensitive and specific biochemical tests for virus detection and differentiation between infectant and inactivated virus is discussed.
