摘要

Members of the genus Serratia are increasingly responsible for nosocomial infections, the treatment of which may be complicated by the appearance of multi-antibiotic-resistant strains. Some but not all Serratia strains and species produce N-acylhomoserine lactones (AHLs), and possess luxR and luxI homologous genes. Phylogenetic comparisons have provided evidence for the lateral transfer of these quorum-sensing systems, and in at least one strain of S. marcescens, transfer via a complex transposon has been experimentally demonstrated. AHL-dependent quorum sensing in Serratia controls population surface migration, biofilm development, the biosynthesis of a carbapenem antibiotic and production of the red pigment, prodigiosin. Serratia also possesses LuxS and produces autoinducer-2 (AI-2) which appears to function as a second quorum-sensing system controlling many of the same phenotypes as the LuxR/AHL systems.
