[Study of viremia in chronic human herpetic infection]

Attempts at virus isolation were made on the blood specimens from patients with relapsing herpesvirus infection. Examinations of over 100 blood specimens from patients with various localizations of herpetic lesions yielded II strains of herpesvirus. In all the cases the virus was isolated from a mixture of leukocytes with erythrocytes of the blood of patients. The method of cocultivation of blood leukocytes with cell cultures was most sensitive and yielded 7 herpesvirus isolates. The herpesvirus isolates vary in their biological and antigenic properties.
