nasopharyngeal swab samples from patients with an acute flu-like illness were evaluated for the presence of respiratory syncytial virus (rsv) from october 1996 to march 1998. the relative frequency and seasonal distribution of rsv was assessed. in addition, the virus correlated with specific clinical signs and symptoms. during the study, 268 samples were collected from children under the age of...

Hospital acquired infections with respiratory syncytial virus are a major problem. The virus is spread predominantly by infected nasal secretions and we investigated whether we could reduce its incidence by cohorting babies on each ward into designated areas and encouraging staff and parents to wash their hands. We examined the incidence of hospital acquired infection due to respiratory syncyti...

Respiratory syncytial virus is a major cause of respiratory disease. There are conflicting accounts of the response of human epithelial cells to respiratory syncytial virus and a lack of data on its effect on ciliary function. Our aim was to study the early stages of respiratory syncytial virus infection of primary human basal and ciliated cultures. Using high speed videomicroscopy, we found th...

Respiratory syncytial virus-induced bronchiolitis has been linked to the development of allergy and atopic asthma. IL-12 and possibly IL-18 are central mediators orchestrating Th1 and/or Th2 immune responses to infection. To determine a possible role for IL-12 in regulating the immune response to acute respiratory syncytial virus infection, IL-12p40 gene-targeted (IL-12p40-/-) and wild-type mic...

It is not known whether respiratory syncytial virus spreads beyond the respiratory tract. With the use of reverse transcriptase polymerase chain reaction, we found viral and transcribed RNA in cells from the arterial blood of four children with bronchiolitis but none in serum or cerebrospinal fluid. Respiratory syncytial virus might therefore spread outside the respiratory tract.

Background and Aims: Respiratory syncytial virus (RSV) infection is common in infants and young children. In infants younger than one year old it may cause bronchiolitis and pneumonia which requires hospitalization. Accurate and rapid diagnosis of the disease will help proper treatment of the disease and prevent further complications. Materials and Methods: Specimen taken from respiratory ...

BACKGROUND Human respiratory syncytial virus usually causes self-limiting upper respiratory infection and occasionally causes pneumonia in immunocompromised hosts. Respiratory syncytial virus-induced severe pneumonia or acute respiratory distress syndrome in immunocompetent adults has been rarely described. Unfortunately, optimal treatment has not been established for this potentially fatal con...

The antiviral effects of bovine interferons on the replication of bovine respiratory tract viruses were studied. Bovine turbinate monolayer cultures were treated with bovine interferons and challenged with several bovine herpesvirus 1 strains, bovine viral diarrhea virus, parainfluenza type 3 virus, goat respiratory syncytial virus, bovine respiratory syncytial virus, bovine adenovirus type 7, ...
