Studies on the kinetics of killing and the proposed mechanism of action of microemulsions against fungi.

Microemulsions are physically stable oil/water clear dispersions, spontaneously formed and thermodynamically stable. They are composed in most cases of water, oil, surfactant and cosurfactant. Microemulsions are stable, self-preserving antimicrobial agents in their own right.

Pseudomonas aeruginosa PAO1 resistance to Zinc pyrithione: phenotypic changes suggest the involvement of efflux pumps.

The aim of this study is to investigate the involvement of an efflux pump in the development of Pseudomonas aeruginosa resistance to zinc pyrithione (ZnPT). In the presence of efflux inhibitor carbonyl cyanide m-chlorophenyl-hydrazone (CCCP), the minimum inhibitory concentration of ZnPT for P. aeruginosa resistant cells is reduced significantly (p < 0.
