Abstract: | "The Enterococcus faecalis conjugative cytolysin plasmid pAD1 encodes a specific aggregation (clumping) response to the peptide sex pheromone cAD1 secreted by plasmid-free strains. Here it is shown that, in the absence of cAD1, exposure of E. faecalis cells harboring pAD1 to subinhibitory concentrations of chloramphenicol, erythromycin, or tetracycline also results in an aggregation response that appears related to a stress-sensitive mechanism associated with a component of the pheromone response" |
