The bacterial colonies were seen around the parabronchial spaces of the lung tissue. I...
Poor vitamin D status has been associated with increased risk and severity of respiratory tract infections. Whether or not inflammation and infection affects 25-hydroxy vitamin D (25(OH)D) concentration is controversial and is important in the interpretation of observational studies using plasma-25(OH)D as a biomarker for status. Our objectives were to measure whether 25(OH)D concentration was ...

BACKGROUND The aim of the study was to evaluate the prevalence of torquetenovirus (TTV) infection in a group of children with recurrent lower respiratory tract infections and radiologic evidence of bronchiectasis. Correlations between TTV loads and severity of bronchiectasis and between TTV loads and lung function were evaluated. METHODS In 38 subjects, high-resolution computed tomography (HR...
Background and purpose: Since adenoviruses could be one of the causes of health problems in children and due to lack of epidemiologic evidences, always will be misdiagnosed with bacterial infections and treated with antibiotics.

Background Influenza immunization of pregnant women protects their young infants against laboratory-confirmed influenza infection. Influenza infection might predispose to subsequent bacterial infections that cause severe pneumonia. In a secondary analysis of a randomized clinical trial (RCT), we evaluated the effect of maternal vaccination on infant hospitalizations for all-cause acute lower re...
Respiratory syncytial virus (RSV) causes recurrent upper and lower Respiratory tract infections (especially pneumonia and bronchiolitis).
