Intracellular movements of Rickettsia conorii and R. typhi based on actin polymerization


Research in Microbiology 143(9): 821-829
Intracellular movements of Rickettsia conorii and R. typhi based on actin polymerization
Human vascular endothelial, Vero and human embryonic lung cells infected with rickettsiae for 24 or 48 h were labelled for polymerized actin with NBD-phallacidin. Between 20 and 68% of the intracellular R. conorii had an actin tail of between 0.33 and 15 micro m, with the longest tails being observed in Vero cells. In the case of R. typhi, <1% of the organisms had actin tails and these were considerably shorter than those of R. conorii.
