title: Shigella flexneri adherence to and multiplication in coxsackie B1 virus-infected HEp-2 cells.
abstract: Coxsackie B1 virus infection enhances the susceptibility of in vitro cultured HEp-2 cells to invasiveness by Shigella flexneri. We have studied the effect of viral infection on two phases of the invasiveness. Only a minor part was mediated by enhanced bacterial adherence to the cells, and the intracellular multiplication was unaffected by the virus. Enhanced adherence was not dependent on the presence of the gene product of the 140 Md virulence associated plasmid. Our data indicate that enhanced invasiveness induced by viral infection is mediated by an effect on other phases of the invasiveness.
