Incidance of multiple antibiotic resistance among strains of pathogenic Legionella pneumophila isolated from cooling towers

Abstract

110 isolates were isolsted and identified as Legionella pneumophila. Antibiotics sensitivity was done to 110 isolates of pathogenic Legionella pneumophila isolates from cooling towers wich cause respiratory diseases. The highest percentage sensitivity of isolates was to Chloramphenicol (96.3%) and the Refampein (96.3%) . while the lowest percentage sensitivity to Polymaxin B (14.5%) and Ceohalothin (18.1%). All above local isolates were resistant (100%) to 5 or more antibiotics .
