Infection is based on agents with a high intrinsic activity, an appropriate pharmacokinetic and pharmacodynamic profile (including the ability to penetrate phagocytic cells), a low incidence of adverse reactions and an advantageous cost–efficacy relationship. Newer macroazalides and fluoroquinolones are among the first-line therapies and in severe infections, particularly those occurring in immunocompromised patients, azithromycin and later fluoroquinolones are the agents of choice. Delay in the onset of adequate therapy is a key factor associated with a poor outcome. Thus, all patients with pneumonia associated with respiratory failure, shock or underlying disease causing severe immunodeficiency should initially receive an agent active against spp. are identified consistently as among the most common causative agents of severe community-acquired pneumonia (CAP).1 Their role in more benign forms of CAP remains controversial. Differences in the patient subsets studied, inclusion criteria and diagnostic methodology, may partly explain apparent discrepancies. In patients with more severe symptoms, requiring a greater degree of hospital care, the percentage of spp. purchase flomax generic Are gram-negative, aerobic, unencapsulated bacilli that are nutritionally fastidious requiring special media for growth. The family Legionellaceae comprises more than 49 species with more than 64 serogroups. The species is responsible for 10 to 50% of nosocomial pneumonias when a hospital's water system is colonized with the organisms. Cases associated with traveling and long term care facilities are increasingly reported worldwide (23, 158, 173). Home-related Legionnaires’ disease have been also described but the risk of contracting Legionnaires’ disease in this setting seems to be very low (144). Aspiration is now known to be the major mode of transmission, although aerosolization also occurs (164). Risk factors include cigarette smoking, receipt of immunosuppressive medications, receipt of prior antibiotics and receipt of a transplant organ.

Legionnaires’ Disease on Rise in US–2016 Update Underrecognized, and underdiagnosed, Legionnaires’ disease can be fatal. Learn what you need to know to recognize and manage this bacterial infection in this CDC Expert Commentary by Laura A. In contrast, for Pontiac fever, treatment is symptomatic, and no antimicrobial therapy is recommended. Therapy effective in patients with legionellosis should be considered for initial empirical treatment for severe community-acquired pneumonia (CAP) and for specific patients with nosocomial pneumonia. Support therapy in patients with shock and respiratory failure is administered as needed.
