A variety of mechanisms contribute to the viral-bacterial synergy which results in fatal secondary bacterial respiratory infections. Epidemiological investigations have implicated physical and psychological stressors as factors contributing to the incidence and severity of respiratory infections and psychological stress alters host responses to experimental viral respiratory infections. The eff...

Humans may be infected by different influenza A viruses--seasonal, pandemic, and zoonotic--which differ in presentation from mild upper respiratory tract disease to severe and sometimes fatal pneumonia with extra-respiratory spread. Differences in spatial and temporal dynamics of these infections are poorly understood. Therefore, we inoculated ferrets with seasonal H3N2, pandemic H1N1 (pH1N1), ...

background :respiratory viruses are the leading cause of respiratory tract infections among children and are responsible for causing morbidity and mortality worldwide. this study was performed to detect viruses in children with respiratory infections and describe their epidemiology and clinical characteristics.   methods : in this descriptive cross sectional study, throat swabs and wash specime...

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...

BACKGROUND Chronic infection with Pseudomonas aeruginosa in patients with cystic fibrosis (CF) is associated with increased morbidity. Chronic infection can cause limb and respiratory muscle compromise. Respiratory muscle function can be assessed via maximal inspiratory pressure (PImax), maximal expiratory pressure (PEmax), and the pressure-time index of the respiratory muscles (PTImus). We stu...

Experts of the Union Pediatricians Russia have developed modern guidelines on management children with acute respiratory viral infection. The term “acute infection” (ARVI) combines following nosological forms: nasopharyngitis, pharyngitis, laryngitis, tracheitis, laryngopharyngitis, upper respiration tract infection (unspecified). issues epidemiology, diagnosis, treatment, and prevention been c...
