In contrast to problems caused by antibiotic resistance in staphylococci, low level resistance to antiseptics has received less attention such resistance is attributable to carriage of plasmids harboring genes which increase tolerance to various agents including quaternary ammonium compounds (qacs) these genes appear to code for efflux pumps which can reduce levels of antiseptic.
