Summary
Development of a method for the cultivation of viruses in cell cultures prepared in small wells in an agar medium has permitted detection by gel-diffusion procedures of specific antigenic materials elaborated by vaccinia virus and adenovirus type 3. The technic, termed the agar-cell culture-precipitation test, permits study of viral components without preliminary concentration thereof, and may find application in investigation of a variety of agents that are obligate intracellular parasites.
