Viruses and atypical bacteria associated with asthma exacerbations in hospitalized children.

Unlabelled: OBJECTIVES AND WORKING HYPOTHESIS: To evaluate the prevalence of respiratory viruses Mycoplasma pneumoniae and Chlamydophila pneumoniae and gain insight into their seasonal circulation pattern in children with acute asthma exacerbations in a temperate southern hemisphere region.

Study Design: Patients hospitalized between 3 months and 16 years of age were included in a 1-year prospective, observational, cross-sectional study. Respiratory secretions were collected and the presence of different viruses and atypical bacteria analyzed by immunofluorescence and polymerase chain reaction.

Objective: To evaluate the prevalence and epidemiological features of newer and traditional respiratory viruses in infants and young children with recurrent wheeze.

Material And Methods: Cross sectional, prospective and descriptive study.
