Because the lung is in constant contact with the environment, infections with respiratory viruses are a common and potentially serious complication of lung transplantation. Infection can cause direct effects, typically manifested as respiratory symptoms and changes in pulmonary function, and indirect effects, such as an enhanced risk of developing chronic allograft rejection. Infections with al...
The diagnostics of respiratory viral infections has improved markedly during the last 15 years with the development of PCR techniques. Since 1997, several new respiratory viruses and their subgroups have been discovered: influenza A viruses H5N1 and H1N1, human metapneumovirus, coronaviruses SARS, NL63 and HKU1, human bocavirus, human rhinoviruses C and D and potential respiratory pathogens, th...
A shell vial assay with simultaneous culture of HEp-2, LLC-MK2, and MDCK cell lines in a single tube (CoHLM SV assay) was compared with traditional tube culture (TC) for the detection of the main respiratory viruses in 358 nasal wash specimens. A total of 170 strains were isolated from 168 virus-positive samples. A total of 94. 1% of the strains (160 strains; 128 respiratory syncytial viruses a...
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...
BACKGROUND Acute respiratory tract infections (ARTIs) represent a serious global health burden. To date, few reports have addressed the prevalence of respiratory viruses (RVs) in adults with ARTIs attending an emergency department (ED). Therefore, the potential impact of respiratory virus infections on such patients remains unknown. METHODOLOGY/PRINCIPAL FINDINGS To determine the epidemiologi...
BACKGROUND It is often difficult for a physician to distinguish between viral and bacterial causes of respiratory infections and this may result in overuse of antibiotics. In many cases of community-acquired respiratory infections, clinicians treat patients empirically. The development of molecular methods for direct detection of viruses has been progressed recently. OBJECTIVES The objective ...
BACKGROUND Viral interaction in which outbreaks of influenza and other common respiratory viruses might affect each other has been postulated by several short studies. Regarding longer time periods, influenza epidemics occasionally occur very early in the season, as during the 2009 pandemic. Whether early occurrence of influenza epidemics impacts outbreaks of other common seasonal viruses is no...
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 specimens ...
SUMMARY Clinical laboratories historically diagnose seven or eight respiratory virus infections using a combination of techniques including enzyme immunoassay, direct fluorescent antibody staining, cell culture, and nucleic acid amplification tests. With the discovery of six new respiratory viruses since 2000, laboratories are faced with the challenge of detecting up to 19 different viruses tha...
