The growing amount of information regarding mucosal immunology in animals resulted from a need to better understand the pathogenesis of diseases entering the body through mucosa surfaces, including the respiratory tract. The second reason for such studies is associated with a search for alternative ways of vaccine application, including delivery to the mucosa of the respiratory tract. This revi...

conclusions: this study indicates that rsv is a substantial cause of respiratory tract infection in infants less than 2 years old. rt-pcr offers a rapid method for detection of rsv in hospitalized children with lrti. results: during the study period, 9 children had a positive result for rsv infection. the median age of these patients was 10 months. bronchiolitis was the clinical diagnosis of pa...

background : to assess the practicability of a new algorithm in decreasing the rate of incorrect diagnoses and inappropriate antibiotic usage in pediatric acute respiratory tract infection (arti ( methods : children between 1 month to15 years brought to outpatient clinics of a children’s hospital with acute respiratory symptoms were managed according to the steps recommended in the algorithm . ...

evidence acquisition this article aims at offering clinicians a brief update on the recent epidemiology of respiratory infections in pediatrics. it also underlines the fact that any evidence-based recommendation needs more research in different areas. context respiratory tract infections are the main cause of children’s morbidity and mortality both in the developing and the developed countries....

BACKGROUND In a substantial proportion of respiratory tract diseases of suspected infectious origin, the etiology is unknown. Some of these cases may be caused by the recently described human bocavirus (hBoV). The aim of this study was to investigate the frequency and the potential clinical relevance of hBoV in pediatric patients. METHODS We tested 835 nasopharyngeal aspirates (NPA) obtained ...

The respiratory tract opens to the external environment at the oral side edge, and the other edge of the respiratory tract connects to the closed space (alveoli), and so to preserve the sterility in the terminal respiratory tract is critical for protection against pathogens. The recognition machinery for the invasion of microbes is indispensable for the preservation of the sterility in the lung...

The nose and lung are both part of the respiratory tract. Often the diseases affecting the nose and/or the bronchi are treated separately. However, in recent years, numerous studies have highlighted the fact that the respiratory system is a single entity and the concept of "united airway disease" has become more and more important. The unity of the respiratory tract is confirmed both from a mor...

Abstract Mycoplasma pulmonis and muris infections have been associated with several diseases in conventionally housed laboratory rat and mice colonies. In naturally infected of mycoplasma pulmonis in mice and rat colonies, the respiratory organ appears to be the favored site of colonization; so, it was not surprising to see that infection spread from the site of urogenital tract to the respirat...

Small airways diseases are not uncommon in childhood. They account for about 28.4% of hospital admissions for lower respiratory tract infections in South West Nigeria, most of which are due to respiratory syncytial virus (RSV) infection. Noninfectious causes of small airways diseases, on the other hand, are poorly recognized and rarely feature in the differential diagnoses of chronic/recurrent ...
