Hyperinvasiveness and increased intercellular spread of Listeria monocytogenes sequence type 1 are independent of listeriolysin S, internalin F and internalin J1

Abstract

Our results underline the importance of using relevant clinical strains when investigating L. monocytogenes virulence. We show that despite the association with CC1, llsB, inlF and inlJ1 are not involved in the hyperinvasiveness and efficient intercellular spread of ST1 in various cell types.
