objectives we assessed the prevalence of three common viruses including; respiratory syncytial virus (rsv), human rhinovirus (hrv), and human metapneumovirus (hmpv), in children with acute wheezing. patients and methods ninety six wheezy children, 48 males (50%) and 48 females (50%)under the age of 5 years, were enrolled in the study. all patients visited as outpatients or inpatients when refer...

conclusions crs is a common disease with negative effects on the quality of patients’ lives. this study showed the high prevalence of these two common respiratory viruses in patients with crs. background chronic rhinosinusitis (crs) is one of the most common chronic illnesses, but the etiology and pathogenesis of crs are not well understood. few studies have been carried out on the role of viru...

conclusions multiplex sybr green real-time pcr is a rapid and relatively inexpensive method for detection of respiratory viruses. results application of the multiplex sybr green real-time pcr in clinical samples from 172 patients in a one-year study resulted in detection of 19 (11.04%) piv3, 9 (5.23%) piv4, and 1 (0.58%) coronavirus nl63. all the positive samples were detected during december t...

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 & Aims: Acute respiratory infections are common cause of mortality during childhood. This study was designed to determine the incidence of adenovirus, parainfluenza virus and respiratory syncytial virus in respiratory infections by Multiplex PCR method. Methods: This study included 168 children under 2 years of age with clinical diagnosis of bronchiolitis. Nasopharyngeal specimens we...

An indirect immunofluorescence respiratory virus panel containing monoclonal antibodies directed against respiratory syncytial virus, parainfluenza virus types 1, 2, and 3, adenovirus, and influenza viruses A and B was used to screen specimens in the nonpeak respiratory syncytial virus seasons in 1989 and 1990. The results indicate that the respiratory virus panel is fairly sensitive (79%) and ...

Comprehensive population-based data on the role of respiratory viruses in the development of lower respiratory tract infections (LRTIs) remain unclear. We investigated the incidence and effect of single and multiple infections with respiratory viruses on the risk of LRTIs in Vietnam. Population-based prospective surveillance and a case-control study of hospitalised paediatric patients with acut...

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, ...
