Antibiotic Susceptibility of Environmental Strains Isolated in Northern Italy.

is ubiquitous in aquatic environments and responsible for severe pneumonia in humans through inhalation of aerosol containing spp. Macrolides and fluoroquinolones are frequently used antimicrobials, but treatment failures are increasingly being reported. As susceptibility testing is not routinely performed, this study aimed to determine the minimum inhibitory concentrations (MICs) on 58 environmental strains (24 of serogroup 1 and 34 of non-serogroup 1) isolated in Northern Italy.
