Legionnaires’ disease: do not forget the fluoroquinolones or macrolides.

Atypical community-acquired pneumonia pathogens, such as Legionella, cause systemic infections with pneumonia. As Legionella infection is likely to present as severe pneumonia, it is important to presumptively diagnose Legionnaires’ disease clinically so that coverage against Legionella spp. is included in the initial empiric antimicrobial therapy.We described a case of respiratory failure secondary to Legionnaires’ disease. An extensive review of the literature about the clinical aspects of Legionnaires’ disease is presented.
