confers_resistance_to_antibiotic erythromycin tetracycline major facilitator superfamily (MFS) antibiotic efflux pump confers_resistance_to_antibiotic chlorhexidine aadT antibiotic_resistance The AadT pump is a novel multidrug efflux pump from the proton antiporter 2 (DHA2) family and was discovered in Acinetobacter multidrug resistance plasmids. The presence of AadT decreased bacterial susceptibility to antibiotics (erythromycin and tetracycline), biocides (chlorhexidine), and dyes (ethidium bromide and DAPI) and was able to mediate ethidium transport.
