Table 3 Quantitative data from the live/dead viability assay

From: Carbon monoxide releasing molecule-2 (CORM-2) inhibits growth of multidrug-resistant uropathogenic Escherichia coli in biofilm and following host cell colonization

Stimuli Mean % ± SEM P value
UPEC 2 control 5 ± 2  
UPEC 2 CORM-2 61 ± 18 0.0208*
UPEC 2 cefotaxime 76 ± 8 0.0011**
ESBL 1 control 6 ± 2  
ESBL 1 CORM-2 60 ± 16 0.0135*
ESBL 1 cefotaxime 5 ± 1  
TG1 control 13 ± 2  
TG1 CORM-2 85 ± 9 0.0003***
TG1 cefotaxime 4 ± 1  
  1. Data show the ratio of dead bacteria (expressed as a percentage) after 24 h exposure to CORM-2 (500 μM), cefotaxime (0.512 μg/ml) or control (DMSO) evaluated by a live/dead viability assay. The ratio of dead bacteria was calculated by manual counting of four randomly selected quadrants (in total covering ¼ from each image) from a representative part of each well. The data are presented as mean ± SEM. (n = 3) *P < 0.05, **P < 0.01, ***P <0.001; CORM-2 or cefotaxime versus control
