Etiologies of Acute Respiratory Tract Infections	2005-08-15		.txt	text/plain	2623	120	52	In this issue of Clinical Infectious Diseases, there are 2 articles that provide us with some insight into the various etiologic agents that can cause acute respiratory tract infection (ARTI) in general practice patients in The Netherlands [1] and into the significance of the human metapneumovirus (hMPV) in patients with community-acquired pneumonia (CAP) and exacerbations of chronic obstructive pulmonary disease (COPD) in Quebec, Canada [2] . The objectives of the Dutch study were to estimate the incidence of influenza-like illnesses (ILIs) and of other ARTIs in patients visiting their general practitioners (to determine the etiologic agents) and to test the hypothesis that asymptomatic persons with subclinical infection may act as sources of transmission [1] . Nose and throat swab specimens were obtained from case patients and control subjects, and viral cultures and PCR tests were performed for detection of adenovirus, coronavirus, enterovirus, hMPV, influenza virus, parainfluenza virus, rhinovirus, and respiratory syncytial virus (RSV), as well as for Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Chlamydophila psittaci.	./cache/cord-260630-vvpzp73r.txt	./txt/cord-260630-vvpzp73r.txt
