title: Plaque morphology of Teschen disease viruses and certain pig enteroviruses in primary pig kidney monolayer cultures.
abstract: Plaque patterns and diameters of four virulent strains and one tissue culture mutant of Teschen disease virus were compared with six pig enteroviruses isolated in the United States. They are described as they were produced in primary pig kidney monolayer cultures. Reproducible plaques, with similar characteristics and class-types of each of the viruses tested were obtained with the application of a 45-minute virus adsorption time. Their morphologic characteristics and the proportion in which the plaque types appeared may assist in the differentiation of these virus strains.
