Immunodiffusion tests are becoming more widely used in virological studies, since this technique was first applied by Jensen and Francis (1953) to the study of viruses belonging to the myxovirus group. Primarily, immunodiffusion tests are used in determining the degree of serological relationship both between closely related viruses — e.g., foot-and-mouth disease viruses (Bodon, 1955; Brown and Crick, 1957) — and within wider groups — e.g., mammalian poxviruses (Gispen, 1955; Westwood et al., 1965; Papadopoulos et al., 1968). Its secondary importance is as a serological tool in the rapid diagnosis of diseases (Villemot and Provost, 1958, 1959; McClurkin, 1963; Estella, 1967).
