Antibody responses to varicella‐zoster virus (VZV) deoxythymidine kinase (dTK) and herpes simplex virus (HSV) dTK in homologous and heterologous infections were studied. Antibodies blocking the enzymatic activity of VZV‐dTK appeared late after varicella and decreased more or less in parallel with the decreasing complement fixing [CF] titre. In herpes zoster, on the other hand, antibodies to VZV‐dTK appeared soon after infection. Antibodies against HSV dTKs appeared long after primary infection, but they were subsequently present in all other HSVCF positive sera. In recurrent HSV, all acute sera were already HSV‐dTK antibody positive, and three of nine persons showed an increase in titer between their acute and convalescent sera. Blocking antibodies to VZV‐dTK appeared rapidly in specimens from three of 18 individuals positive by an immunofluorescence VZV‐immunity test during HSV infection, whereas all other specimens remained devoid of blocking antibodies against VZV‐dTK. A rise in antibody titre against HSV‐dTK during VZV infections was observed in serum specimens from three of 13 HSV‐CF positive patients, whereas an antibody response against HSV‐dTK was not found in HSV‐CF negative individuals in conection with VZV infections. The relevance of the sporadic increase in the titres of antibodies against heterologous viral dTKs is discussed.
