Fig. 1From: Histamine H1 receptor antagonists enhance the efficacy of antibacterials against Escherichia coliRepresentative example for the result of one checkerboard experiment with colistin and mepyramine. The lines show the growth of E. coli ATCC® 25922™ after 24 h depending on different colistin and mepyramine concentrations in combination. For colistin in combination with 300 μg/ml mepyramine the MIC of E. coli ATCC® 25922™ was reduced from 8.0 to 1.0 μg/mlBack to article page
