Ursolic acid synergistically potentiates bactericidal effect of colistin in infected zebrafish. E. coli U3790 and K. pneumoniae BC936 were intramuscularly injected in zebrafish and treated with either colistin (Col)/ursolic acid (UR) or colistin + ursolic acid in combination for 24 h. Following treatment, fish were euthanized and the muscle tissue was collected in PBS, homogenized, serially diluted and plated onto LB agar. The colony counts was scored after 24 h and represented as log CFU/ml. The error bar represents the standard error of mean of three independent samples
