摘要

Members of the Burkholderia cepacia complex can secrete proteases, lipases, and hemolysins. We report in this study the identification of a general secretory pathway present in a B. vietnamiensis (formerly genomovar V) clinical isolate, which is required for the efficient secretion of phospholipase C and hemolysin activities. Southern blot hybridization experiments revealed that this general secretion pathway is highly conserved among the different genomovars of the B. cepacia complex and is homologous to a similar system described in B. pseudomallei. We also show that this pathway appears not to be necessary for intracellular survival of B. vietnamiensis within Acanthamoeba polyphaga.
