Table 2 Competitive indexes (CIs)a for mice infections between the reference strain SL1344, human invasive strains 33676 and YU39, and the SPI-2 mutant strain ΔssrB

From: A multi-drug resistant Salmonella Typhimurium ST213 human-invasive strain (33676) containing the bla CMY-2 gene on an IncF plasmid is attenuated for virulence in BALB/c mice

  1. a CI values lower than 1 indicate virulence attenuation. For most mice no bacteria were detected for strains 33676, YU39 and ΔssrB; thus, the values showed represent the lower detection limit for these assays
