GASP phenotype: presence in enterobacteria and independence of sigmaS in its acquisition.
The appearance of growth advantage in stationary phase or GASP was originally detected in Escherichia coli. The presence of this phenotype in other enterobacteria such as Enterobacter cloacae, Salmonella typhimurium, Providencia stuartii and Shigella dysenteriae is described in this work. E. cloacae GASP strains presented lower levels of RpoS than the parental strain, although no mutation in the gene or its promoter was detected. This work offers evidence of GASP rpoS-independent pathways as GASP was also acquired in knock-out rpoS E. cloacae and E. coli strains.
