THE ETIOLOGIC AGENTS OF VARICELLA AND HERPES ZOSTER

Abstract
The preparation of antigenic materials capable of specific fixation of complement in the presence of convalescent phase sera from patients with varicella and herpes zoster is described. Satisfactory antigens were obtained by the repetitive harvest and subsequent concentration of the pooled nutrient fluids from bottle cultures of human embryonic skin-muscle tissue or of monkey kidney tissue infected with varicella or herpes zoster viruses. Specific fixation of complement was also demonstrated with antigens prepared from extracts of the infected cell sheets harvested from bottle cultures.
