Abstract: (15713 Views)
Background and objectives: Sub-minimum inhibitory concentration (S-MIC) can induce changes in
morphology, virulence factors and biochemical properties ofbacterial pathogens. The goal of this study is to
determine the Sub-MIC effect of ciprofloxacin and ampicillin on the haemotytic activity of E. coli.
Material and Methods:Two clinical isolates of E. coli with high heamolytic activity was selected. Changes in haemolytic activity of the isolates was assessed after exposing them to MIC and Sub-MIC of ciprofloxacin and ampicillin.
Results: Ciprofloxacin decreased haemolytic activity at 1/2, 1/4 and 1/8 Sub-Mic, whereas ampicillin showed no effect on haemolytic activity.
Conclusion: We conclude that Sub-MIC concentrations of ciprofloxacin decreased the haemolytic activity of E. coli, wherease ampicillin had no such effect
