The association of biofilm formation and sub-minimal inhibitory concentrations of antimicrobial agents
Introduction: Although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-MICs) of some antimicrobial agents. Therefore, we designed present study to investigate the in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, merop...
متن کاملInhibitory effect of zinc oxide nanoparticles on pseudomonas aeruginosa biofilm formation
Objective(s): Bacterial biofilm formation causes many persistent and chronic infections. The matrix protects biofilm bacteria from exposure to innate immune defenses and antibiotic treatments. The purpose of this study was to evaluate the biofilm formation of clinical isolates of Pseudomonas aeruginosa and the activity of zinc oxide nanoparticles (ZnO NPs) on biofilm. Materials and Methods: Aft...
متن کاملinhibitory effects of plant extracts on pseudomonas aeruginosa biofilm formation
results results showed desirable antimicrobial effects of the silver nanoparticles and plant extract on the formation of the pseudomonas aeruginosa biofilm and the highest effect was observed in silver nanoparticles and the lowest inhibitory effects were observed in bucks beard and prangos ferulaceae. conclusions medicinal plants used in the study decreased the rate of biofilm formation. since ...
متن کاملSub-minimum inhibitory concentrations of colistin and polymyxin B promote Acinetobacter baumannii biofilm formation
We investigated the numbers of planktonic and biofilm cells and the expression levels of genes encoding efflux pumps and biofilm-related proteins in 10 clinical isolates of multi-drug resistant Acinetobacter baumannii (MDRA) as well as in its standard strain ATCC 19606 in the presence of colistin (CST), polymyxin B (PMB), minomycin (MIN), and tigecycline (TGC) at their respective sub-MICs. The ...
متن کاملSub-Minimum Inhibitory Concentrations of Rhubarb Water Extracts Inhibit Streptococcus suis Biofilm Formation
Streptococcus suis is one of the most important swine pathogens, which can cause persistent infection by forming biofilms. In this study, sub-minimum inhibitory concentration (sub-MIC) of rhubarb water extracts were found to inhibit biofilm formation. Two-component signal transduction systems (TCSs), transcriptional regulators, and DNA binding proteins were compared under two conditions: (1) ce...
