Fig. 2From: Characterization of Escherichia coli isolated from urinary tract infection and association between virulence expression and antimicrobial susceptibilityEffect of ciprofloxacin and ceftriaxone on the hemolytic activities of uropathogenic Escherichia coli isolates. Cultures were grown in the absence (untreated) or presence of 0.25 sub-inhibitory concentrations of antibiotics. Deionized water was used as a positive control. Values represent the meanāĀ±āstandard deviation of three independent assays.* indicates Pā<ā0.05 when compared to the untreated (antibiotic-free) cultureBack to article page
