Mycoplasma pneumoniae and Legionella pneumophila in community-acquired lower respiratory tract infections among hospitalized children: diagnosis by real time PCR.

Mycoplasma pneumoniae and Legionella pneumophila are increasingly recognized as important agents of community-acquired lower respiratory tract infections (LRTI). Mycoplasma pneumoniae has been also recognized as a cause of nosocomial infections. The aim of this study was to investigate the role of real time polymerase chain reaction (PCR) for the rapid diagnosis of these infections among hospitalized children with community-acquired LRTI.

Q fever in children in Greece.

The aim of this study was to investigate the incidence, epidemiology, and clinical manifestations of Q fever among hospitalized children in Greece. During a two-year period, 1,200 children with various clinical manifestations were prospectively tested for Coxiella burnetii infection by indirect immunofluorescence. Acute Q fever was diagnosed in eight (0.

Lack of association between Kawasaki syndrome and infection with Rickettsia conorii, Rickettsia typhi, Coxiella burnetii or Ehrlichia phagocytophila group.

Background: The etiology of Kawasaki syndrome (KS) is unknown. Rickettsiae, intracellular microorganisms that invade the vascular endothelium, might cause KS.

Objectives: To investigate whether there is an association between KS and infection with Rickettsia conorii, Rickettsia typhi, Coxiella burnetii or Ehrlichia phagocytophila group.
