Objective To explore whether active efflux system exists in Staphylococcus epidermidis so as to evaluate the drug resistant mechanism of Staphylococcus epidermidis to fluoroquinolones.

Objective: To investigate the possible presence ofan active efflux system in resistance tofluoroquinolones in Mycoplasma hominis.

The objective of the experiment is to detect and confirm the effect of active efflux system in the mechanism of bacterial multi-drug resistance.

This article reviewed the hazard to livestock and mankind caused by Shigella,the classification of Shigella and its state of multidrug resistant in clinic,and also the feature of main drug resistance system acrAB-tolC and advance of drug resistance related gene:hdeA,tolB,tolA,tolQ,the medicamentous outside transport protein:marA,acrA,acrB etc.

Distribution and expression of active efflux pump acrAB in clinical isolates of Shigella;

Initial Exploration of Drug Active Efflux Pump of Fluconazole-resistant Candida Albicans;

Conclusion The multi-resistance of Acinetobacter baumannii was related to the effect of efflux system.

Objective To evaluate the role of outer membrane protein (Omp) F-deficiency and active efflux in the accumulation of hydrophilic fluoroquinolones ciprofloxacin (CPLX) and lomefloxacin (LMLX) in resistant E.

To identify if there was the mechanism of active efflux in erythromycin resistant Streptococcus strains with mefA gene isolated from veterinary clinic,several erythromycin resistant strains with mefA gene,ermB gene and several susceptible strains were selected in this test.

Objective To study the effects of active efflux inhibitor on the activities of quinolones against staphylococcus aureus,and investigate the prevalence of active efflux-mediated staphylococcus aureus in our hospital.
