- Abstract
The nucleotide sequence downstream from the rpoS gene in Enterobacter cloacae and Kluyvera cryocrescens contains the slyA–pad1–yclC genes. The DNA sequence of Enterobacter cloacae CETC960 shows a 2.6-kb insertion of unknown origin between rpoS and slyA. This 2.6-kb sequence has also been detected in species of Salmonella and in Pseudomonas aeruginosa, but not in the same location. This insertion has been detected in all the Enterobacter cloacae clinical strains studied although the size of the rpoS-yclC region was highly variable, possibly owing to the presence of insertions and/or deletions. The study of the rpoS-mutS region in other enterobacteria also showed variability in size. Our results support the idea of a variational hot spot in the rpoS-mutS region that could be related to pathogenesis and horizontal transfer. Correspondence to: J.M.
