Two independent experiments showing the survival of Galleria mellonella following inoculation with 10 colony-forming units (CFU) of S. marcescens clinical isolates SJC1043, SJC1051, or their derivatives with exchanged betR alleles, and incubation at 37°C (n =26 larvae for each strain; survival curves are significantly different by log-rank (Mantel-Cox) test with p values as shown). SJC1043 BetR1051 indicates SJC1043 with the betR allele from SJC1051 and vice versa.
