Antibiotic Resistance and Azithromycin Resistance Mechanism of Legionella pneumophila Serogroup 1 in China.

ABSTRACT: Legionnaires' disease, caused by Legionella pneumophila, has been treated primarily with antibiotics. However, few reports have been published on antibiotic-resistant Legionella in China. Our aim was to determine the azithromycin resistance mechanism of L. pneumophila serogroup 1 in China. The sensitivities of 149 L. pneumophila serogroup 1 strains, isolated from clinical cases or environmental water in China from 2002 to 2016, to five antibiotics, including erythromycin, azithromycin, levofloxacin, moxifloxacin, and rifampin, were evaluated. The mechanisms of the resistance of L. pneumophila serogroup 1 to azithromycin were studied. The expression levels of efflux pump gene lpeAB and the MIC of azithromycin-resistant strains in the presence and absence of the efflux pump inhibitor carbony
