Article Title: When more is less: Emergent suppressive interactions in three-drug combinations

doi: 10.1186/s12866-017-1017-3

Figure Lengend Snippet: Comparison of suppressive interactions in pairwise versus emergent three-drug interactions. Bars represent the proportion of interactions that are classified as antagonistic suppressive in pairwise interactions (black) and in three-drug interactions (white) for three bacteria strains: wild-type, non-pathogenic E. coli BW25113; pathogenic E. coli CFT073; and non-pathogenic S. epidermidis 14990. For the data presented in this paper, 95% confidence intervals resulting from bootstrapping experiments are shown

Article Snippet: Additionally, drug combinations were also tested in (1) the pathogenic E. coli strain CFT073, a highly virulent pyelonephritis strain isolated from human clinical specimen (from ATCC) and (2) Staphylococcus epidermidis 14990 (from ATCC).

Figure Lengend Snippet: Suppressive three-drug interactions in E. coli BW25113. Growth measurements are shown for bacteria in single-drug, two-drug, and three-drug conditions relative to the no-drug control (100% growth, not shown). Emergent suppression was determined following Tekin et al. (see ). The upper left figure is a schematic with X, Y, and Z representing three different drugs. Only the experimental data for the three-drug combination (X + Y + Z), the suppressed pairwise drug combination with the lowest growth (Y + Z), and the suppressor single drug (X) is shown. 46 triple combinations of a total 327 interaction measures were determined to be suppressive. Antibiotic abbreviations are as listed in Table

Article Snippet: Additionally, drug combinations were also tested in (1) the pathogenic E. coli strain CFT073, a highly virulent pyelonephritis strain isolated from human clinical specimen (from ATCC) and (2) Staphylococcus epidermidis 14990 (from ATCC).
