Acinetobacter baumannii is a rod-shaped Gram-negative bacterium that commonly inhabits soil. A. baumannii is highly resistant to various antimicrobials, and multidrug clinical isolates have been isolated all over the world including in Canada. Our hypothesis is that efflux pumps belonging to the Resistance-Nodulation-cell Division (RND) family aid in the survival of A. baumannii in the presence of harmful compounds (including antimicrobials, heavy metals, detergents, and dyes), and that characterization of these efflux pumps will contribute to an understanding of the survival mechanisms employed by this organism. Using powerful molecular and genetic tools, this program will characterize three RND complex-encoding operons,

鲍曼尼（Baumannii）的杆菌是一种通常居住在土壤中的棒状革兰氏阴性细菌。鲍曼尼曲霉对各种抗菌素具有高度耐药性，并且在包括加拿大在内的世界各地都分离了多药临床分离株。我们的假设是，在存在有害化合物的情况下（包括抗菌素，重金属，洗涤剂和染料），属于抗抗性突出细胞分裂（RND）家庭援助的外排泵，可为这些外排泵的特性而促进这种生存机构的理解。使用强大的分子和遗传工具，该程序将表征三个RND复合编码操纵子，即
