Sažetak

Background and purpose: The aim of this study was to examine the influence of subminimal inhibitory concentrations (subMICs) of ceftazidime, ciprofloxacin and gentamicin on the adherence ability and morphology of wild-type Pseudomonas aeruginosa strains to the Buffalo green monkey kidney cell line, using indirect immunofluorescence staining.


Materials and methods: Bacterial adherence changes were tested before and after exposure to 1/2, 1/4, 1/8, 1/16 and 1/32 MIC of antibiotics.


Results: A statistical difference in the number of attached bacteria after exposure to all subMICs of ceftazidime and ciprofloxacin was observed (p<0.05), even after only 1/2 MIC of gentamicin.


Conclusion: The results of this study have shown that antibiotics in much lower concentrations than those necessary for inhibition of bacterial multiplications could damage the adherence of Pseudomonas aeruginosa to the epithelial cell line.
