AuthorTitle AbstractChange
Xueqing WU 14323 - Cadmium stimulates biofilm formation by Staphylococcus epidermidislast paragraph:
Up-regulation of atlE (10.5 folds), embp (5.4 folds), icaA (22.1 folds), icaB (26.8 folds) and agrB (3.9 folds) after exposure to 3.13 µM cadmium was observed in planktonic bacteria. No gene dysregulation was observed in biofilm bacteria. In conclusion, at concentrations of 1.56 or 3.13 µM, cadmium stimulates S. epidermidis biofilm formation and adversely affects cell viability. Modification in gene expression was observed in planktonic bacteria but not in those enclosed in the biofilm.
