Different E. coli strains are capable of adsorbing Coxsackie B3, B5, and poliomyelitis viruses. Virus adsorbed on bacteria can be detected from the cytopathic effect in tissue culture and by the plaque assay procedure the amount of virus will be expressed in TCD50 on plaque-forming units, respectively. Titration of adsorbed virus by the plaque assay procedure reveals the quantitative fluctuations in adsorption more distinctly. The factors directly responsible for the adsorption of the different bacterial strains could not be determined.
