In vitro infection of mouse pancreatic islet cells with coxsackie viruses.

We have demonstrated the ability of 4 standard coxsackie viruses (B4, B5, A7, and A9) and one fresh isolate (A7) from a newly diabetic child with homologous serological response, to infect in vitro grown mouse pancreatic islet cells. Up to the 9th day after infection the multiplication of viruses in the cells was proved using virus titration and immunofluorescence test. Isolated pancreatic cells proved to be a suitable model for detailed studies of experimental infection of pancreatic cells with coxsackie viruses.
