The Sensitivity of Legionella pneumophila to Common Antibiotics

The study included sensitivity of 43 isolates of Legionella pneumophila (L. pneumophila) isolated from 150 samples of different water sources. The bacterium was identified depending on morphological, cultural and biochemical tests.The results showed that these isolates exhibit different sensetivity for antibiotics that used in this study. It showed high sensitivity to Azithromycin (93%) which was higher than Erythromycin that used widely in treatment of the infections of this bacteria (81.4 %), while it showed sensitivity to Cephalothin and Vancomycin with respectively (7%, 14%). The isolates showed clear difference in the rate of their sensitivity and resistance to other antibiotics used in this study.
